General Commands

3.4.1 Command 0x01 - Response ACK

This command retrieves the status of the most recent command the host has sent to the device. The host
should call this command immediately after it sends a command to the device, to determine whether the
device accepted the command as sent. The data the device returns includes an ACKSTS code (see
Appendix C Status and Message Table) and the ID of the command the status is for.
Table 3-1 - Usage Table for Command 0x01
Bit 7
Byte 0 0x01
Status of command ("ACKSTS")
Byte 1
Byte 2 ID of command being ACKed
Byte 3 reserved
Byte 4 reserved
For example, after sending Command 0x03 - Request Swipe Card to the device, the host should
immediately call 0x01 Response ACK. If the command executed correctly, the ACKSTS would be
0x00; if the host included bad parameters in the command, the ACKSTS would be Bad Parameter
(0x82), as specified in the documentation of Command 0x03 - Request Swipe Card.

3.4.2 Command 0x02 - End Session

This command clears all existing session data including PIN, PAN, and amount. The device returns to
the idle state and sets the display to the specified Welcome screen.
