Description The PIN, which was entered with the WFS_PIN_GET_PIN command, is combined with the requisite data specified by the Eurocheque validation algorithm and locally verified for correctness. The result of the verification is returned to the application. This command will clear the PIN.
Input Param LPWFSPINLOCALEUROCHEQUE lpLocalEurocheque;
typedef struct _wfs_pin_local_eurocheque
{
LPSTR lpsEurochequeData;
LPSTR lpsPVV;
WORD wFirstEncDigits;
WORD wFirstEncOffset;
WORD wPVVDigits;
WORD wPVVOffset;
LPSTR lpsKey;
LPWFSXDATA lpxKeyEncKey;
LPSTR lpsDecTable;
} WFSPINLOCALEUROCHEQUE, * LPWFSPINLOCALEUROCHEQUE;
lpsEurochequeData
Track-3 Eurocheque data
lpsPVV
PIN Validation Value from track data.
wFirstEncDigits
Number of digits to extract after first encryption.
wFirstEncOffset
Offset of digits to extract after first encryption.
wPVVDigits
Number of digits to extract for PVV.
wPVVOffset
Offset of digits to extract for PVV.
lpsKey
Name of the validation key.
lpxKeyEncKey
If NULL, lpsKey is used directly for PIN validation. Otherwise, lpsKey is used to decrypt the encrypted key passed in lpxKeyEncKey and the result is used for PIN validation.
lpsDecTable
ASCII decimalization table (16 character string containing characters ‘0’ to ‘9’). Used to convert the hexadecimal digits (0x0 to 0xF) of the encrypted validation data to decimal digits (0x0 to 0x9).
Output Param LPBOOL lpbResult;
lpbResult
Pointer to a boolean value which specifies whether the PIN is correct or not.
