Simplify supports Stand-in processing for offline situations based on configured settings (see Stand-in Processing for more information). A parameter controls whether EMV tags are sent to the POS in offline responses. The only other modifications to offline processing for EMV are that: ( 1) If EMV print data is returned on an offline response, the POS must print the data. (2) Simplify does not validate the expiration date for offline EMV transactions.
Traditionally EMV tags are not returned in a Stand-In response. Simplify can now be set to return EMV tags to the POS in Stand-In. This allows the POS to process offline forwards as EMV transactions.
