LoopPay

http://youtu.be/0hBAa0iWFgw?t=2m53s "for restaurants, simply tell the waiter you want to pay at their cardreader". Um, cancels out a massive amount of places that you'll be using your card to pay at. Coin totally blows this out of the water.

This is a fascinating product and the technology behind it seems awesome. The issues with payments are not swiping a credit card (or using a terminal), it's mostly with the management of cards, the cost to the vendor and the experience of paying the bill or managing finances. This product doesn't necessarily solve all of them but, along with Coin, I believe it's heading in the right direction.

@_jacksmith I worry about the security of coin. I'm a yc alum and love what coin is trying to build but their product raises a number of security and functionality concerns. EMV credit cards also cannot be cloned. I think in the USA many people are switching to EMV as well.

@datarade could you expand on what you mean by 'functionality concerns'? Security is not a problem at all for Coin; they have a huge number of considerations in place and it's probably more secure than using your normal card. They'll also support EMV when it gets proper proliferation across the USA (it's going to take about $50Bn in investment to upgrade all the points of service etc. and I wouldn't expect for at least another 3 years, they're aiming 2017).
