Would be cool if they supported chip and pin and paypass.

I came here to make a similar comment. We need more companies pushing adoption of EMV here in the states. I know it isn't a perfect solution, but it is certainly better than the mag-stripe situation we have today. It makes me nervous whenever I see one of these devices being used in the wild. The first generation of Square devices were very easy to siphon raw track data off of. As a customer, how do I know that the device you have attached to your personal phone is secure? I don't know the security behind the latest generations of these devices, but it still makes me uneasy swiping my credit card on someone's personal device that has who-knows-what malware on it.

I wonder if these kind of initiatives slow the adoption of chip and pin credit cards in the US. If Amazon is willing to lower the fees for swipes, pin entered transactions could be even lower.

I think that one of the problems for chip and pin adoption in the US is that there isn't a compelling reason for US consumers to desire it.

Credit card fraud might be a pain-point for merchants, but it simply is not for consumers. On the rare occasion that somebody makes a fraudulent purchase on my credit card, my credit card company flags the transaction. In the exceptionally rare case that this fails, I just call my credit card company and tell them that the transaction was fraudulent. Takes no more than 5 minutes, and I can count the number of times I've had to do it in the past 10 years on one hand.

Why then would I want the hassle of punching in a PIN? I'm a consumer, not a merchant. I don't care about what benefits the merchant gets out of it.
