Cancel Message (Tran Type 80)

Simplify supports a Cancel message from the POS process. When Simplify receives a Cancel Request, it will attempt to cancel the transaction (return to the Closed state) and send a Cancel Response to the POS.

The Cancel message is available to allow the POS process to clear the PIN Pad. This message should be used if the POS process and the PIN Pad are out of sync.
