If a customer presents a credit card that has not been signed, what is the appropriate action?

When a customer presents a credit card that has not been signed, the appropriate action is to not accept the card until it is signed. This policy is in place to protect both the customer and the merchant from potential fraud. A signature on the back of the card serves as a method of identification and verification, ensuring that the person using the card is indeed the authorized cardholder.

Allowing an unsigned card could lead to unauthorized transactions, which could result in financial loss and liability issues for the business. In the event of any disputes regarding the transaction, having a signed card provides a layer of security and proof that the transaction was authorized by the cardholder. Therefore, requiring a signature reinforces good business practices and safeguards against potential fraud.
