Prototype:

unsigned short GetCardTypeList(unsigned char readType, unsigned char *PAN, unsigned char PANLen, BIN_DATA_t* binData);

Input Parameters:

readType: The method of the card read.

#define READ_TYPE_ICC 0x01

#define READ_TYPE_MSR 0x02

#define READ_TYPE_ICC2MSR 0x03

#define READ_TYPE_KEYIN 0x04

#define READ_TYPE_CLESS 0x05

PAN: card number.

PANLen: length of the card number.

Output Parameters:

binData: Current Txn No of the requested sale in Batch.

typedef struct {
    char bankAppName[25];     //The name of the CAP start with BNK_
    char bankName[50];  // ?  //Official Bank Name in the field
    unsigned char cardType; 
} BIN_DATA_t;

#define CARD_TYPE_NONE 0x01

#define CARD_TYPE_NOT_ONUS 0x02

#define CARD_TYPE_BRAND 0x04

Return Value:

Return Value:

0 : Success.

-1, 1 : Error

3.3 GetSetupParameters
