I ran across this article today about this product that apparently enables our customers to:

"re-program their own magnetic stripes and hide their account numbers, providing added security for bank customers who don’t want to carry lots of plastic inside RFID-proof metal wallets."

I'm not sure if I see a problem with this or not. Anyone?

Here is the article:
