This would be a trojan of the ATM card world. It looks like a real ATM card and can be endorsed by a bank or credit company if only for advertising purposes.

When someone uses it for whatever reason, it alerts the business owner who receives it and can further work with a security system to tell it to record the timecode for the video cameras at the precise moment said theif uses your fake card. Like any other ATM card it can also make the reader dial into a bank to alert them of the theif or the local police so they can get the tape from the store and use it as evidence to nab the right suspect.

There are many stores here that will accept a signature instead of a PIN.

Did you possibly have your ATM card stolen recently [sartep]? Your ideas seem a little one track at the moment.

No, I just recently used it at several places where all I needed was a signature.

12 years later I had the same Idea. I must get out more.
