1. Before any card commands, get the Reader Handle first.
2. Select the TAG.
3. Login the TAG.
4. Access the TAG.
5. Close the Reader Handle.
// ACR120_Sample.c; a very simple program
#include “acr120.h”
void main(void)
{
INT16 hReader;
UINT8 Length, SN[10], Data[16], Type;
// Open a communication channel (USB Interface)
hReader=ACR120_Open(ACR120_USB1);
if(hReader<0){ // error happened!!! };
// Assume the Reader Handle is ready, then “Select a TAG”
ACR120_Select(hReader, &Type, &Length, SN);
// Assume a TAG is selected, then “Login Sector 0x00”
ACR120_Login(hReader, 0x00, AC_MIFARE_LOGIN_KEYTYPE_DEFAULT_A,0,NULL);
// Assume the Sector is authorized, then “Read data from Block 0x02 of
Sector 0x00”
ACR120_Read(hReader, 0x02, Data);
/*
Some operations.
*/
ACR120_Close(hReader); // Close the port and quit the program
