I was at a store, and the cashier scanned my check and then handed it back to me. Is this normal?

The scan will capture the specific numbers on the check so that it can be identified on your bank statement. You can hold on to the check for your records, but don’t use it to make another payment, even to the same merchant, because your bank or credit union may reject it.

The retailer or other person must display a sign about their practice of scanning checks close to where it accepts checks, such as in the checkout line.

Notify your bank as soon as possible if you notice any errors or unauthorized transactions. You have substantial rights under the Electronic Funds Transfer Act.
