Stand-In and Online Response Differences
The main differences between a Stand-in Response and an Online Response occur in the following fields:
|Field #||Field Name||Usage|
|1003||Gateway Response Code|
|1010||Gateway Response Message|
|1379||EMV Receipt Field List||EMV Receipt data available for printing.|
A value of “*SLR STAND-IN.” in field 1010 does not mean that Simplify has performed stand-in; it indicates that Simplify did not receive a Host Response before timing out. The POS performs Stand-in by deciding whether or not to approve the transaction locally.
