參考 MS VB.COMPATIBILITY

需要三個 dll 檔案

透過參考加入 dll

讀卡號

Imports VB = Microsoft.VisualBasicImports GIGATMS.NF.MifareReaderImports GIGATMS.NF.GNetPlus‘ 宣告全域變數‘建立物件 mf5x1

Public WithEvents MF5x1 As New GIGATMS.NF.MifareReader

‘卡號Public Id As Integer

透過 mf5x1 物件讀取卡號Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles

Button1.Click MF5x1.mfRequest() ' 對機器發出命令要求讀取

' 讀取卡號 Id = MF5x1.mfAnticollision If Id <> 0 Then Select Case MF5x1.mfCurrentClass Case iCardTypeConstants.MIFARE_UltraLight, iCardTypeConstants.MIFARE_DESFire TextBox1.Text = VB.Left(Id.ToString("X").PadLeft(8, "0"), 6) Case Else TextBox1.Text = Id.ToString("X").PadLeft(8, "0") End Select Else TextBox1.Text = MF5x1.GNetErrorCodeStr End IfEnd Sub

執行結果

出了甚麼問題？

Port 需要啟動Private Sub Form1_Load(ByVal sender As

• 改變任一個 READER 上 sector 的 KEY• 試試是否可以讀取資料？

存 KEY 入 TAG

• 卡片要先通過認證，才能執行動作

Private CB3, CB1, CB0, CB2 As Short Private Sub Button5_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click CB0 = 0 CB1 = 0 CB2 = 0 CB3 = 4
