The POS process will receive a Stand-In Response (Field 1010 contains *SLR STAND-IN.) if Stand-In is enabled.
This response contains encrypted transaction data allowing the transaction to be locally approved as a Stand-In transaction and resubmitted through Simplify for host approval.
IMPORTANT: The POS is responsible for deciding whether or not to approve the transaction by Stand-In. In either case, Inquiry processing must be performed at some point, as described in Recommended Rules for Handling If the transaction is locally approved, Inquiry processing must be completed (by receiving a Fusebox approval or decline to the original transaction, or a No Record response) before resubmitting the original transaction.
Note: The POS is responsible for validating the card type and expiration date on all Stand-in transactions.
