Stand-in Response 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 For an Online Response, contains the Fusebox returned token for the account number.

For a Stand-in Response, if a token is used for authorization, the token is returned. Otherwise, this field contains the encrypted version of the account number. This encrypted version of the account is what should be sent by the POS system, in Field 3, when the transaction is resubmitted. This encrypted version of the account number is generated by the PIN Pad, after the customer’s card is swiped. If the account was keyed-in, this field contains the encrypted keyed data.
4 Expiration Date For a Stand-in Response, contains the encrypted Expiration Date, if the card was keyed.
6 Authorization Code For an Online Response, contains the approval code returned by Fusebox.

For a Stand-in Response, contains the string SN: followed by the Serial Number of the PIN Pad.
1003 Gateway Response Code For a Stand-In Response, contains “0000”.
1010 Gateway Response Message For a Stand-in Response, this field contains the text “,*SLR STAND-IN.”

Note: Field 1010: A value of *SLR STAND-IN. in this field does not mean that Simplify has performed stand-in; it indicates that Simplify did not receive a Host Response before timing out. The POS decides whether to perform stand-in (approve the transaction locally).
