BMW car keys could soon double as your credit card

BMW and NXP are set to demo a prototype key at the CARTES & IDentification show in Paris next month that will double as your credit card. While the concept is nothing new with the advent of those fancy little key fobs that let you pay for items with a simple swipe. We have something like that in NYC for the subways with one of the banks. It’s nice to know the automotive industry is finally getting on the bandwagon.

This is all well and good, but what if you have to pay a toll or something? You don’t exactly want to be turning the car off to take the key out of the ignition to pay for stuff. Just a scenario where I don’t think this would be ideal.
