Exit Reversal Mode Message (Tran Type 36-12)
Simplify supports an Exit Reversal Mode message from the POS.
Simplify uses reversal mode to force a host reversal after the ICC (Integrated Circuit Card) declines a host-approved EMV transaction or the customer removes the ICC before a host-approved transaction is completed. If this occurs, a reversal request will be sent for the approved transaction, and resent if necessary, until a host response is received. While in reversal mode, all other transactions on the PIN Pad will be processed offline.
The POS can force Simplify to exit reversal mode by sending an Exit Reversal Mode message. Simplify will respond by sending a Void Transaction Response (11) message to the POS, including the data required to request the reversal. The PIN Pad will then return to normal processing mode. If this message is sent and Simplify is not in reversal mode, it will just echo back the same message it receives.
IMPORTANT: Forcing Simplify to exit reversal mode is an exception procedure that should only be used when necessary. If Simplify is forced out of reversal mode, the merchant will be responsible for ensuring that the transaction is reversed by the host, using the data in the Void Transaction Response. Elavon strongly recommends allowing Simplify to reverse all host-approved ICC-declined transactions.
Note: The POS can also force Simplify to exit reversal mode from within the Elavon Main Menu on the PIN Pad. See the Simplify Download Configuration and Troubleshooting Guide for details.
