Implementing TLS 1.2 to Simplify
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.
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
