They say this supports chip-and-PIN, but I don't believe them until they explain how. If I have a chip-and-PIN card from my bank, the chip has an unreadable secret used to generate one-time cryptograms to verify the authenticity of the card. There's no way to get that secret onto my Plastc card. You'd need partnerships with banks to get a new secret the way Apple Pay does. Without those, this sounds like it'll be use…

On the bottom of their wallet tab [1], they list several participating banks, so it sounds like they might have those partnerships you mention. [1] https://www.plastc.com/wallet

Interesting that the list of banks is nearly the same as that of ApplePay. I'm glad there are some forward-thinking enough banks willing to push technology forward.

What need does this address? Are cards taking up too much room in people's lives? This solution doesn't reduce the height or width of the encumbrance at all, and reduces the depth only by n*.76mm, where n is the number of cards that will be replaced. I don't get it. Also, http://c2.com/cgi/wiki?TheZenOfProgramming

It seems pretty solidly in the "luxury" column. This is particularly clear if you take a long view. It's likely that all physical credit cards are on their way out in favor of digitally distributed credentials. CC companies like you flashing their cards, but not as much as they like lowering fraud.

That being said, it's certainly attractive. If the 'bubble bursts' (whatever that means), I expect this is the kind of start up that will be first against the wall. Just remember frivolous != worthless.

Lot of comments here is how Apple pay will rule. But not everybody can or want to buy iPhone. Or even expensive Android with NFC... That is why I think Coin and Plastc - if little cheaper may be succesfull. I usually have 2-3 debt cards, one credit card and I have few bonus cards for different stores - that I do not take with me, because I like small wallet. This solves my problem.

I'm guessing it pairs with your phone, and automatically wipes once it disconnects (maybe after some timeout).

I would assume the same thing, the problem is if I leave my wallet upstairs and take my phone downstairs (breaking the BTLE tether) will it also wipe? If so does it automatically re-load when I get back in range? If it doesn't auto-reload then it sounds like a PITA and if it does auto-reload it sounds like a security nightmare (Clone the BTLE MAC and get the victims phones to unknowingly push all their charge cards t…

My thoughts exactly.

Am I do only one having a huge (yet still growing) list of preordered and backed projects and waiting for their delivery? If I sum up the pending ones up, it's thousands of dollars. If I put all that money in the stock market and buy the products after they are on the market, and read the reviews, I'm sure I'll be saving money and not be worried that I'm getting schemed all the time.

Now I think this is a difficult-to-implement idea too, but not for the reasons you mentioned 1. eink can be made on flexible plastic and be very thin, and cheap too (see http://www.engadget.com/2008/09/08/esquires-e-ink-infused-ma... ) 2. charge pumps can be made out of discrete components and the largest part is a coil, which can easily be laid flat and thin. You can also charge a ceramic cap (low self discharge) sl…

1. With respect to e-ink on a flexible substrate... it was announced but I've never seen it happen. I've dealt with e-ink fairly recently on two projects. They don't have a flexible design to sell you beyond prototype. and for custom sizes Their MOQ to begin exploring a custom option is 100K units. 2. There is no coil in a charge pump :). They use capacitors and switches. There is no inductor. For a charge pump to dr…

A prototype is a requirement here. Seeing the team, I see no technical person, but two brand designers (just the people to make a great demo video). Not to say they don't have someone who can pull this off, but it is a thing that has not been done before exactly. Like Lockitron, Coin, and others before, the variety of physical interfaces involved plus the need for it to work 100% of the time make this non-trivial. This is not just a neat digital interface problem.

Hmm, I thought this might be what Coin turned into but I see that onlycoin.com is still taking pre-orders for their all-in-one card. I get the consumer appeal but find the appeal for the banks less strong. I would love a one time credit card app where every time you swiped it, it changed numbers. And it seems making the card 'smart' like this could enable that sort of thing.
