Recommended Rules for Handling

The recommended rules for handling Stand-in Responses are as follows:

  • All responses with “*SLR STAND-IN.” need to be recorded by the POS (Stand-In List). This includes all transactions that were either locally approved or locally declined.
  • Go through the Stand In-List.
    • If the POS processed the transaction as approved, send an Inquiry.
      • If Inquiry response is APPROVED (Transaction Type = original), POS processing is done.
      • If Inquiry response is NO RECORD FOUND (Transaction Type = 22), submit the Stand-in Transaction for processing.
    • If the POS processed the transaction as declined, send an Inquiry.
      • If Inquiry response is APPROVED (Transaction Type = original), send a void.
      • If Inquiry response is NO RECORDS FOUND (Transaction Type = 22), POS processing is done.
