Offline Situations

Simplify supports Stand-In processing for offline situations based on configured settings; see POS SAF Processing for more information. When a transaction is processed offline, a Simplify-generated response message is returned to the POS in field 1010 of the Stand-In Response; see Simplify-Generated Messages.

Traditionally EMV tags are not returned in a Stand-In response. Starting with version 2.02.023, 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:

  • If EMV print data is returned on an offline response, the POS must print the data.
  • Simplify does not validate the expiration date for offline EMV transactions.
