New Credit Cards Incorporate Security Key Fob Features

This new kind of credit card being shown off at trade shows is designed to prevent against loss due to identity theft by incorporating a security key fob with a credit card. The idea is that when you buy online, swipe at the store, or take money out of the ATM, you hit a button to randomly generate a unique, disposable key code. Enter that code to verify the transaction. This way, someone would actually have to steal your physical credit card to conduct fraud. Best of all, it's the same size and thickness as a regular credit card.We had a type of key-fob for computer access at a previous job of mine. The fob had a buttons to enter a PIN and then would display the OTP. If you screwed up the PIN a preset number of times then it would lock the fob until it was brought back to the IT department and unlocked. I know one guy who finally convinced the IT department to do away with the lockout feature on his fob because his 2-year old son thought the fob was a toy and kept locking it up
