Simplify-Generated Messages

Simplify-generated response messages are used for transactions processed offline. This will occur if a transaction is declined locally (no host message) or if the host is unavailable.

note

If On-Device SAF is enabled, a different set of Simplify-generated messages will be used for offline situations. See Simplify-Generated Messages for On-Device SAF.

For EMV, Simplify will also generate a response message if the chip declines a host-approved transaction or the customer removes the card before the transaction is completed.

Simplify-generated response messages are indicated by an asterisk (*) as the first character of the message. The first four characters indicate the type of transaction as follows:

*SLR – non-EMV

*ICC – contact or contactless EMV
