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.
