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 NameUsage
3Account Data
  • Online - Token for the account number (from the Fusebox response)
  • Stand-in - If a token is used for authorization, the token is returned. Otherwise, this field contains the encrypted version of the account number.
4Expiration Date
  • Stand-in - If the card was keyed, contains encrypted Expiration Date.
6Authorization Code
  • Online - Approval code returned by Fusebox.
  • Stand-in - “SN:” followed by the Serial Number of the PIN Pad.
1003Gateway Response Code
  • Stand-in - “0000”
1010Gateway Response Message
  • Stand-in - “*SLR STAND-IN.”
1379EMV Receipt Field ListEMV Receipt data available for printing.
  • Online - From Fusebox, for use on declines (see EMV Receipts in the Fusebox Integration Guide for more information).
  • Stand-in - From Simplify (same format as online).

note

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.
