ICC (Chip) Declines and Simplify Reversal Mode
On this page:
Introduction
If the ICC (chip card) declines a host-approved transaction, or the customer removes their card from the chip reader before a host-approved transaction is completed, the host approval will need to be reversed.
If one of these scenarios occurs, the message in field 1010 will begin with *ICC (see Simplify-Generated Messages) and field 26 will specify the reason for the reversal. 2 = Chip requested decline: 3 = Premature EMV card removal.
If a host approval needs to be reversed, Simplify will send an EMV decline of the original transaction to the POS and go into reversal mode to force a host reversal. In reversal mode, Simplify sends the reversal (Tran Type 11) to the host, and resends it if necessary, until a response is received. While this is taking place, any other transactions sent to the PIN Pad will be processed offline. After Simplify receives an approval of the reversal, it will return to normal processing mode.
Alternatively, the POS can force Simplify out of reversal mode by sending an Exit Reversal Mode (36-12) message. Simplify will respond by sending a Void Sale 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.) See below for format and sample message exchange.
(Simplify can also be forced to exit reversal mode from within the Elavon Main Menu on the PIN Pad; see the Simplify Download Configuration Troubleshooting Guide under “Exiting Reversal Mode” for details.)
important
Forcing Simplify to exit reversal mode is an exception procedure that should only be used when necessary. Affected transactions must be reviewed to ensure that customers have been correctly charged.
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 Sale Response. Elavon strongly recommends allowing Simplify to use reversal mode to reverse all host-approved transactions that are declined by the chip.
