Simplify supports Stand-In processing for offline situations based on configured settings; see Stand-in Processing.
Traditionally EMV tags are not returned in a Stand-In response. Starting with version 2.19, Simplify can be set to return EMV tags to the POS in Stand-In. This allows the POS to process Store and Forward (deferred authorization) transactions as EMV.
Other changes to offline processing for EMV: ( 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.
