MSR_AUTHENTICATE_DEVICE structure (pointofservicedriverinterface.h)

This structure provides the authentication information used to authenticate a device.

Syntax

typedef struct _MSR_AUTHENTICATE_DEVICE {
  unsigned char Size;
  unsigned char Challenge1[MSR_CHALLENGE_SIZE];
  unsigned char SessionId[MSR_SESSION_ID_SIZE];
} MSR_AUTHENTICATE_DEVICE, *PMSR_AUTHENTICATE_DEVICE;

Members

Size

If the optional SessionId is present, this will include the size of SessionId[MSR_SESSION_ID_SIZE]

Challenge1[MSR_CHALLENGE_SIZE]

The challenge token.

SessionId[MSR_SESSION_ID_SIZE]

The session ID. This is primarily used to identify each transaction so that you can prevent errors such as processing the same transaction twice.
