How Do AT Work An ATM is simply a data terminal with two input and four output devices. Like any other data terminal, the ATM has to connect to, and communicate through, a host processor . The host processor is analogous toan Internet service provider  (IS! in that it is the gateway through which all the various ATM networks

"ecome availa"le to the cardholder (the person wanting the cash!.

Most host processors can support either leased-line or dial-up machines. Leased#line machines connectdirectly to the host processor through a four#wire, point#to#point, dedicated telephone line. $ial#up ATMsconnect to the host processor through a normal phone line using a modem and a toll#free num"er, orthrough an Internet service provider using a local access num"er dialed "y modem.

Leased#line ATMs are preferred for very high#volume locations "ecause of their thru-put capa"ility, and dial#up ATMs are preferred for retail merchant locations where cost is a greater factor than thru#put. The initialcost for a dial#up machine is less than half that for a leased#line machine. The monthly operating costs fordial#up are only a fraction of the costs for leased#line.

Parts of the Machine%ou&re pro"a"ly one of the millions who has used an ATM. As you know, an ATM has two input devices'

← Card reader  # The card reader captures the account information stored on the magnetic stripe on

the "ack of an ATMde"it or credit card. The host processor uses this information to route the transaction tothe cardholder&s "ank.

← Keypad # The keypad lets the cardholder tell the "ank what kind of transaction is re)uired (cash

withdrawal, "alance in)uiry, etc.! and for what amount. Also, the "ank re)uires the cardholder&s personalidentification num"er (PI! for verification. *ederal law re)uires that the I+ "lock "e sent to the hostprocessor in encrypted form.

 And an ATM has four output devices'

← !peaker  # The speaker  provides the cardholder with auditory feed"ack when a key is pressed.

←

Display screen # The display screen prompts the cardholder through each step of the transactionprocess. Leased#line machines commonly use a monochrome or color  -T (cathode ray tu"e! display. $ial#up machines commonly use a monochrome or color  L$. 

← "eceipt printer  # The receipt printer provides the cardholder with a paper receipt of the

transaction.

← Cash dispenser  # The heart of an ATM is the safe and cash#dispensing mechanism. The entire

"ottom portion of most small ATMs is a safe that contains the cash.

!ensin# $ills The cash#dispensing mechanism has an electric eye that counts each "ill as it eits the dispenser. The "illcount and all of the information pertaining to a particular transaction is recorded in a  %ournal. The /ournalinformation is printed out periodically and a hard copy is maintained "y the machine owner for two years.

0henever a cardholder has a dispute a"out a transaction, he or she can ask for a /ournal printout showingthe transaction, and then contact the host processor. If no one is availa"le to provide the /ournal printout, thecardholder needs to notify the "ank or institution that issued the card and fill out a form that will "e faed tothe host processor. It is the host processor&s responsi"ility to resolve the dispute.

1esides the electric eye that counts each "ill, the cash#dispensing mechanism also has a sensor  thatevaluates the thickness of each "ill. If two "ills are stuck together, then instead of "eing dispensed to thecardholder they are diverted to a re%ect &in. The same thing happens with a "ill that is ecessively worn,torn, or folded.

The num"er of re%ect &ills is also recorded so that the machine owner can "e aware of the )uality of "illsthat are "eing loaded into the machine. A high re/ect rate would indicate a pro"lem with the "ills or with thedispenser mechanism.

 ATMs for the 2isually ImpairedThere are ATMs that are accessi"le to "lind and visually impairedpeople. These machines are located at kiosks rather than "ank drive#thrus. And the keypads at ATMs are e)uipped with &raille.

!ettlement 'unds0hen a cardholder wants to do an ATM transaction, he or sheprovides the necessary information "y means of the card reader andkeypad. The ATM forwards this information to the host processor,which routes the transaction re)uest to the cardholder&s "ank or theinstitution that issued the card. If the cardholder is re)uesting cash,the host processor causes an electronic funds transfer  to takeplace from the customer&s "ank account to the host processor&saccount. 3nce the funds are transferred to the host processor&s "ankaccount, the processor sends an appro(al code to the ATMauthori4ing the machine to dispense the cash. The processor then A5s the cardholder&s funds into the merchant&s "ank account,usually the net "ank "usiness day. In this way, the merchant isreim&ursed for all funds dispensed "y the ATM.

An independent ATM host can access any &ank) It also supports alar#e num&er of ATMs placed with different merchants)

So when you re)uest cash, the money moves electronically from your account to the host&s account to themerchant&s account.

ATM !ecurity ATMs keep your personal identification num"er (PI! and other information safe "y using encryption software such as Triple $6S ($ata 6ncryption Standard!. 1ut there are lots of things that you can do toprotect your information and your money at an ATM.

Many "anks recommend that you select your own PI. 2isa offers the following I+ tips'

← $on&t write down your I+. If you must write it down, do not store it in your wallet or purse.

ACH Transfers

←  Avoid using "irth dates, initials, house num"ers or your phone num"er . 

2isa also recommends the following tips for safe ATM usage'

← Store your ATM card in your purse or wallet, in an area where it won&t get scratched or "ent.

← 8et your card out 16*3-6 you approach the ATM. %ou&ll "e more vulnera"le to attack if you&re

standing in front of the ATM, fum"ling through your wallet for your card.← Stand directly in front of the ATM keypad when typing in your I+. This prevents anyone waiting to

use the machine from seeing your personal information.

←  After your transaction, take your receipt, card and money away. $o not stand in front of the

machine and count your money.

← If you are using a drive#up ATM, get your vehicle as close to the machine as possi"le to prevent

anyone from coming up to your window. Also make sure that your doors are locked "efore you drive up tothe machine.

← $o not leave your car running while using a walk#up ATM. Take your keys with you and lock the

doors "efore your transaction.

← If someone or something makes you uncomforta"le, cancel your transaction and leave the machine

immediately. *ollow up with your "ank to make sure the transaction was cancelled and alert the "ank to anysuspicious people.

Many retail merchants close their store at night. It is strongly recommended that they pull the money out ofthe machine when they close, /ust like they do with their cash registers, and leave the door to the securitycompartment wide open like they do with an empty cash#register drawer. This makes it o"vious to anywould#"e thief that this is not payday.

How Credit Cards Work

5ave you ever stood "ehind someone in line at the store and watched him shuffle through a stack of whatmust "e at least 9: credit cards; onsumers with this many cards are still in the minority, "ut eperts saythat the ma/ority of <.S. citi4ens have at least one credit card ## and usually two or three. It&s true that creditcards have "ecome important sources of identification ## if you want to rent a car , for eample, you reallyneed a ma/or credit card. And used wisely, a credit card can provide convenience and allow you to makepurchases with nearly a month to pay for them "efore finance charges kick in.

That sounds good, in theory. 1ut in reality, many consumers are una"le to take advantage of these "enefits"ecause they carry a "alance on their credit card from month to month, paying finance charges that can goup to a whopping => percent. Many find it hard to resist using the old 7plastic7 for impulse purchases or"uying things they really can&t afford. The num"ers are striking' In 9???, American consumers charged a"out@9.= trillion on their general#purpose credit cards.

In this article we&ll look at the credit card ## how it works "oth financially and technically ## and we&ll offer tipson how to shop for a credit card. (6perts say this should "e a pro/ect on the scale of shopping for a  car loanor  mortgage! 0e&ll also descri"e the different credit#card plans availa"le, talk a"out your credit history and

how that might affect your card options, and discuss how to avoid credit#card fraud ## "oth online and in thereal world.

Let&s start at the "eginning. A credit card is a thin plastic card, usually >#9B inches "y =#9B inches in si4e,that contains identification information such as a signature or picture, and authori4es the person named on itto charge purchases or services to his account ## charges for which he will "e "illed periodically. Today, theinformation on the card is read "y automated teller machines (ATMs!, store readers, and "ank and Internetcomputers.

 According to 6ncyclopedia 1ritannica, the use of credit cards originated in the <nited States during the9?=:s, when individual companies, such as hotel chains and oil companies, "egan issuing them tocustomers for purchases made at those "usinesses. This use increased significantly after 0orld 0ar II.

The first uni(ersal credit card ## one that could "e used at a variety of stores and "usinesses ## wasintroduced "y $iners lu", Inc., in 9?C:. 0ith this system, the credit#card company charged cardholders anannual fee and "illed them on a monthly or yearly "asis. Another ma/or universal card ## 7$on&t leave homewithout it7 ## was esta"lished in 9?CB "y the American 6press company.

Later came the "ank credit#card system. <nder this plan, the "ank credits the account of the merchant assales slips are received (this means merchants are paid )uickly ## something they love! and assem"lescharges to "e "illed to the cardholder at the end of the "illing period. The cardholder, in turn, pays the "ankeither the entire "alance or in monthly installments with interest (sometimes called carryin# char#es!.

The first national "ank plan was $ankAmericard, which was started on a statewide "asis in 9?C? "y the$ank of America in alifornia. This system was licensed in other states starting in 9?DD, and was renamed2isa in 9?ED.

3ther ma/or "ank cards followed, including Masterard, formerly Master harge. In order to offer epandedservices, such as meals and lodging, many smaller "anks that earlier offered credit cards on a local orregional "asis formed relationships with large national or international "anks.

The !tripe on a Credit Card

Illustration "y -osaleah -autert%our card has a magstripe on the "ack and a place for your all#important signature.

The stripe on the "ack of a credit card is a ma#netic stripe, often called a ma#stripe. The magstripe ismade up of tiny iron#"ased magnetic particles in a plastic#like film. 6ach particle is really a tiny &ar ma#net 

a"out =:#millionths of an inch long.The magstripe can "e 7written7 "ecause the tiny "ar magnets can "e ma#neti9ed in either a north or southpole direction. The magstripe on the "ack of the card is very similar to a piece of cassette tape (see 5owassette Tapes 0ork for details!.

 A magstripe reader (you may have seen one hooked to someone&s  at a "a4aar or fair! can understandthe information on the three-track stripe. If the ATM isn&t accepting your card, your pro"lem is pro"a"lyeither'

←  A dirty or scratched magstripe

←  An erased magstripe (The most common causes for erased magstripes are eposure to magnets,

like the small ones used to hold notes and pictures on the refrigerator , and eposure to a store&s electronicarticle surveillance (6AS! tag demagneti4er.!There are three tracks on the magstripe. 6ach track is a"out one#tenth of an inch wide. The IS3I6standard EB99, which is used "y "anks, specifies'

← Track one is =9: "its per inch ("pi!, and holds E? D#"it plus parity "it read#only characters.

← Track two is EC "pi, and holds G: G#"it plus parity "it characters.

← Track three is =9: "pi, and holds 9:E G#"it plus parity "it characters.

%our credit card typically uses only tracks one and two. Track three is a readwrite track (which includes anencrypted I+, country code, currency units and amount authori4ed!, "ut its usage is not standardi4edamong "anks.

The information on track one is contained in two formats' A, which is reserved for proprietary use of the cardissuer, and 1, which includes the following'

← !tart sentinel # one character

← 'ormat code:;$; # one character (alpha only!

← Primary account num&er  # up to 9? characters

There are three "asic methods for determining whether your credit card will pay for what you&re charging'

← 7lectronic data capture (6$! magstripe#card swipe terminals are "ecoming more common ## so

← 4irtual terminals on the Internet

This is how it works' After you or the cashier swipes your credit card through a reader, the 6$ software atthe point-of-sale (3S! terminal dials a stored telephone num"er (using a modem! to call an ac=uirer . Anac)uirer is an organi4ation that collects credit#authentication re)uests from merchants and provides themerchants with a payment guarantee.

0hen the ac)uirer company gets the credit#card authentication re)uest, it checks the transaction for validityand the record on the magstripe for'

Single dial#up transactions are processed at 9,=:: to =,G:: "its per second ("ps!, while direct Internet attachment uses much higher speeds via this protocol. In this system, the cardholder enters a personalidentification num&er  (I+! using a keypad.

The I+ is not on the card ## it is encrypted (hidden in code! in a data"ase. (*or eample, "efore you getcash from an ATM, the ATM encrypts the I+ and sends it to the data"ase to see if there is a match.! TheI+ can "e either in the "ank&s computers in an encrypted form (as a cipher ! or encrypted on the card itself.

The transformation used in this type of cryptography is called one-way. This means that it&s easy to computea cipher given the "ank&s key and the customer&s PI, "ut not computationally feasi"le to o"tain the plain#tet I+ from the cipher, even if the key is known. This feature was designed to protect the cardholder from"eing impersonated "y someone who has access to the "ank&s computer files.

Likewise, the communications "etween the ATM and the "ank&s central computer are encrypted to preventwould#"e thieves from tapping into the phone lines, recording the signals sent to the ATM to authori4e thedispensing of cash and then feeding the same signals to the ATM to trick it into unauthori4ed dispensing ofcash.

If this isn&t enough protection to ease your mind, there are now cards that utili4e even more securitymeasures than your conventional credit card' Smart ards.

ui4 As you can see, the "asic process of a de"it transaction is not complicated. 1ut why would you choose touse a de"it card instead of a credit card;

*irst let&s compare de"it and credit cards.

De&it Cards (s) Credit Cards

hoto "y 0athi) Jhu4aie8etty Images1anks in 1aghdad have started issuing de"it cards to customers, as advertised "y this employee of 0arka1ank on March 99, =::B.

$e"it cards and credit cards each have advantages and disadvantages. The "iggest advantage of de"it

cards over credit cards is that you don&t need to worry a"out interest rates, monthly "ills and financecharges. Since a de"it card uses only the money you actually have, you won&t "uild up an unmanagea"lede"t "y using it, as you might with unchecked use of a credit card. redit cards, after all, accrue interest onunpaid "alances. <nless you pay off your "alance every month, you will always end up paying more for aT2, for eample, than what the T2 actually cost.

redit card limits are often )uite high, sometimes significantly higher than the average monthly "alance inyour checking account. If you aren&t careful, your credit card "alance can grow out of control. The limit onyour de"it card, on the other hand, is whatever you have in your checking account.

 Another advantage of the de"it card is how easy it is to ac)uire one. %ou can get a de"it card with prettymuch any checking account, whereas you can o"tain a credit card only "y applying for one. A de"it carddoes not re)uire an investigation into your credit historyF most credit cards do re)uire a credit check.

 A Matter of onvenience

 According to a study "y the *ederal -eserve 1oard, BB.9 percent of de"it card holders use de"itcards "ecause of their convenience, while only C.B percent of holders use de"it cards to lasso intheir spending ha"its Ksource' 1or4ekowski, Jiser and Ahmed.Hust as the advantage of a de"it card is that it draws on your actual funds, the disadvantage of a de"it cardis that you are limited "y those funds. %ou can overdraw your checking account, which can result in your"ank charging an overdraft fee. These fees can reach up to @=C Ksource' 1ankrate. 1ut you can also goover your credit card limit, which results in a similar fee, and this fee can accrue interest. $e"it cards don&tlicense you to "e irresponsi"le in your spendingF you should always keep ta"s on your transactions andaccount "alance.

3ne advantage of credit cards over de"it cards is that they can help you to make very large purchases thatwould "e otherwise impossi"le, such as that plasma T2 you&ve "een eyeing. 1ut it is easy with credit cardsto feel like you can "uy whatever you want, whenever you want. Live and spend within your means. (*ormore information on how to do that, take a look at 5ow $iscretionary 6penses 0ork and Ten Tips forStaying on 1udget.!

 A disadvantage of de"it cards is the amount of "uying protection provided to you "y law. $e"it cardtransactions very much resem"le cash transactions. The money changes hands )uickly, and it&s difficult to

get it "ack. If you want to return a "roken or unsatisfactory item you purchased with a de"it card, many"usinesses will only give you an echange or store credit.

 Also, it&s worth noting that the laws that police stolen de"it cards aren&t as friendly as the laws that policestolen credit cards. %ou may find it more difficult to get your money when a highway ro""er steals your de"itcard than when a highway ro""er lifts your credit card. Learn more on the net page.

Choosin# to >se a De&it CardThere are several things to consider when choosing whether to use a de"it card. $e"it cards are "est forsmall, run#of#the#mill purchases ## the "o of doughnuts for the "oys at work or the "ottle of water  from thecorner store as you walk to the "each on a hot day. 0hen you get into large items like computers, T2s andfurniture, it&s usually "etter to use a credit card. These purchases can put a "ig dent in your finances ## adent you might not "e a"le to afford in one "ig hit. Spread over several months of credit card payments, thecost of a large item "ecomes more managea"le.

$e"it cards are convenient for "oth the customer and the merchant.  hecks can "e annoying to write,cum"ersome to deposit and slow to clear. $e"it card transactions usually clear within =G hours. lus,"usiness esta"lishments accept de"it cards more often than they accept checks, and "usinesses generallypay less to process de"it card payments than they do to process credit card payments.

The 6lectronic *unds Transfer Act gives "anks ten days to look into reports of 7unauthori4edtransactions7 and decide whether your case holds water. Some "anks will give you an infusion offunds to cover the loss if the investigation is going to take awhile. Some will not. Ask your "anka"out its policies on unauthori4ed transactions Ksource' *$I.Something to keep in mind when using a de"it card is that some "usinesses, such as hotels and gasstations, put a hold on your card to ensure that they are paid for their product or service. *or eample, gasstations will often put a @C: hold on your card and then charge you for the actual cost of the gas you

pumped. As soon as they receive the money due them, they will lift the @C: hold. If you use a de"it card ongas purchases, this @C: hold could influence the availa"le "alance in your checking account, affecting otherpurchases you might make "efore the hold is lifted.

If you choose to use a de"it card, make sure you protect your card and account information. Jeep your I+safeF don&t carry it around on a slip of paper tucked into your wallet. Memori4e it. Also, don&t make your I+something o"vious, a num"er that a thief could easily connect to other identifying information, such as yourstreet num"er or a se)uence of digits from your phone num"er. retty much anyone can get this identifyinginformation, so don&t make it easy for a thief.

 As we discussed on the previous page, if your de"it card is stolen, you may find it more difficult to get yourmoney "ack than you would if your credit card were stolen. <nder the 6lectronic *und Transfer Act, as longas you report your card stolen within two days, you won&t lose more than @C: of the money a thief drawsfrom your account. If you don&t report for up to D: days, you could "e lia"le for as much as @C::. 1eyond D:days ## well, let&s hope you have a good supply of money in another account. Luckily, 2isa and Masterard,as well as many "anks, will not hold you lia"le for de"it transactions you did not authori4e.

signing up for a credit card, you agree to pay "ack the money that you "orrowed,in addition to any interest drawn on the amount you "orrowed.

Debit . 3dds are, you have a de"it card in your wallet or purse right now, sincemany ATM cards are programmed to have de"it options. Issued "y your "ank,de"it cards take funds directly from the money that you have in your "ankaccount##in a sense acting like a check, /ust faster. 0ith a de"it card, you don&thave to carry cash or checks, and it is very convenient to shop at a variety ofplaces including gas stations, grocery stores, restaurants, and retail stores.

In this article, we&ll look at the types of electronic payment, discuss its "enefits and limitations and eplainhow to add e#payment capa"ility to your 0e" site.

Methods and Types of 6lectronic ayment

 An electronic payment is any kind of non#cash payment that doesn&t involve a paper check. Methods ofelectronic payments include credit cards, de"it cards and the ACH (Automated learing 5ouse! network.The A5 system comprises direct deposit, direct de"it and electronic checks (e#checks!.

*or all these methods of electronic payment, there are three main types of transactions'

ourtesy  Ama4on9. A one-time customer-to-(endor payment is commonly used when you shop online at an e#

commmerce site, such as  Ama4on. %ou click on the shopping cart icon, type in your credit card informationand click on the checkout "utton. The site processes your credit card information and sends you an e#mailnotifiying you that your payment was received. 3n some 0e" sites, you can use an e#check instead of acredit card. To pay "y e#check, you type in your account num"er and your "ank&s routing num"er. Thevendor authori4es payment through the customer&s "ank, which then either initiates an electronic fundstransfer  (6*T! or prints a check and mails it to the vendor.

=. %ou make a recurrin# customer-to-(endor payment when you pay a "ill through a regularlyscheduled direct de"it from your checking account or an automatic charge to your credit card. This type ofpayment plan is commonly offered "y car insurance companies, phone companies and loan managementcompanies. Some long#term contracts (like those at gyms or fitness centers! re)uire this type of automatedpayment schedule.

>. To use automatic &ank-to-(endor payment, your "ank must offer a service called online &ill pay.%ou log on to your "ank&s 0e" site, enter the vendor&s information and authori4e your "ank to electronicallytransfer money from your account to pay your "ill. In most cases, you can choose whether to do thismanually for each "illing cycle or have your "ills automatically paid on the same day each month.+et, we&ll discuss some of the "enefits of electronic payment.

1enefits of 6lectronic ayment

6lectronic payment is very convenient for the consumer. In most cases, you only need to enter your accountinformation ## such as your credit card num"er and shipping address ## once. The information is then storedin a data"ase on the retailer&s 0e" server . 0hen you come "ack to the 0e" site, you /ust log in with yourusername and password. ompleting a transaction is as simple as clicking your mouse' All you have to do isconfirm your purchase and you&re done.

6lectronic payment lowers costs for "usinesses. The more payments they can process electronically, theless they spend on paper and postage. 3ffering electronic payment can also help "usinesses improvecustomer retention. A customer is more likely to return to the same e#commerce site where his or herinformation has already "een entered and stored.
