How does a bank verify the signature of its customers?

Question

Quizplus · Accepted Answer

Banks typically verify the signature of their customers by comparing it to the signature card filled in by the customer when the account is opened. This ensures that the signature on any subsequent documents, checks or transactions matches the customer's original signature on file, and helps prevent fraud. While other methods such as substitute checks, ID cards and pin numbers may be used for additional security measures, they are not typically used as the primary method of signature verification.
