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 |
|---|---|---|
| 3 | Account 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. |
| 4 | Expiration Date | Stand-in - If the card was keyed, contains encrypted Expiration Date. |
| 6 | Authorization Code | Online - Approval code returned by Fusebox. Stand-in - “SN:” followed by the Serial Number of the PIN Pad. |
| 1003 | Gateway Response Code | Stand-in - “0000” |
| 1010 | Gateway Response Message | Stand-in - “*SLR STAND-IN.” |
| 1379 | EMV Receipt Field List | EMV 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.
