> "...a problem most of us have."

Is this a real problem? I'm going to go out on a limb and say that you can't determine a problem by telling me this is a problem we all have. I'm not buying the angle, sorry. Not like I'm against this idea, but the sell is a little ridiculous.

How would this work with chip-based cards? In Canada, some of the banks have ditched the magstripe, so not sure how scalable this is - since the encryption on the chip is specifically engineered to prevent this kind of interception.
