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 Online:
      From Fusebox, for use on declines (see the Fusebox EMV section under "EMV Receipts" for more information).
    Stand-in:
      From Simplify (same format as online).

    note

    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.
