My bank changes the expiration date every few years for security. Then I have to change it at Amazon.

Does your bank change it also periodically?

Most sites require the 3 digit validation code to be entered. Amazon does not do this and that is a unique weakness at the Amazon site.

By the way, your credit card information could also be stolen by a bank employee. Do you use a major bank or a local bank? Local banks are notorious for weakened security since they have less revenue to cover the expense of advanced procedures and may take more short cuts.

We once had a local bank discard old customer records into an outside garbage bin without shredding it first. Luckily, someone found it and turned it back to the bank. Any criminal could have easily compromised it. I also once saw in the local newspapers that a bank employee had his laptop stolen with all the customer records on it. The bank offered free identity protection to all it's customers and many did have their credit card numbers used improperly.
