When you suspect fraud

  • If your employees are suspicious about a card or a cardholder at any time during a transaction, tell them to call the Authorization Center and request a Code 10 authorization.
  • A Code 10 authorization request alerts the card issuer to suspicious activity — without alerting the customer. During a Code 10 call, your acquirer may ask for transaction details. Your call will be transferred to the card issuer's special operator who will provide instructions on any necessary action.
  • When the operator picks up, train your employees to say, "I have a code 10 Authorization Request," and then follow these steps:
  1. Stay calm to avoid alarming the person who presented the card.
  2. Keep the card in question in hand to address any questions.
  3. Answer the operator's questions in a normal tone, with a simple "yes" or "no."
  4. Follow the operator's instructions.
  5. For your staff's safety, do not, under any circumstances, confront or try to apprehend the customer.

Reporting fraud

Sometimes fraud happens even with strong preventive measures in place. Keep contact information for reporting fraud easily accessible, and make sure your employees know how to use it.
