Earlier quoted context omitted.

I understand chip+pin is still a novelty in the US. Back in 2009, I was (apparently) the first person to use the chip+pin machine in one of the biggest bookstores in Toronto - the cashiers got excited and all gathered round to watch. It was a little bit bizarre.

I was in the UK with my non-chip and pin card and there was a similar response. It took like 5 people at Tesco to figure it out.

Yeah, I can't remember the last time I saw someone sign for or swipe a credit card in the UK: it's all chip-and-pin now, all the time. This looks like cool technology but it just wouldn't work here.

So I have to turn this over to a bartender to keep behind the bar when I go out and drink? If I forget to grab it before I take a cab, now I'm out $100 and ALL of my credit cards. No thanks.

Is that system still popular? I've started lots of tabs in the last few years, and it's always been purely an oral conversation - they only get my card at the end when I'm settling up.

Dear downvoter , please tell me something innovative you did in life , other than throwing downvotes . What is happening to HN ? I work in a small start-up and I know what efforts it takes to build something instead of downvoting or discouraging.

Seems crazy that it only holds 8 cards. I'm not about to go through all this effort only to replace some of the cards in my wallet but not all of them.

Most of the cards in my wallet aren't credit/debit cards anyway. Drivers license, health insurance, etc. etc.

This wouldn't be able to replace my wallet, so I'd still be carrying two things around with me.

Super cool, but my guess is that there's a very small time window for it to succeed before the phone completely subsumes all card functionality. After all, the phone already scans the old card and sends the details to the 'CoinCard' (and monitors card-custody) via Bluetooth-LE.

It won't be long before most swipe terminals are themselves augmented with wireless transceivers, making the "CoinCard" a redundant middleman-device. That is, your phone could just send archived magstripe details, after your onscreen-app confirmation of payment-intent, to the retailer's terminal.

Coin's real strategy may be for that world - the hardware will fall away like a first-stage-rocket at some point... even faster, say, than Netflix moved from DVDs-through-mail to pure-network-delivery.

What happens when the waiter accidentally clicks the button & charges your business card when it should have charged your personal card? I guess they can just peruse your cards, see what you've got, and pick which one to charge. :p

Presumably when the card is away from your phone (and BT connectivity), it would disable the button on the card. Or you could lock it into selecting that card via the phone.

Imagine you've dropped your phone somewhere (or had it picked out of your pocket) and tada, now your credit cards no longer work! As a result you're temporarily part of the nouveau poor and can't call anybody for help if you're out and about on your own.

I'm slapping my head and thinking "this is such a great idea, why didn't I think of that?". I'm sure lots of other people are doing the same, and it's a sign of a truly great idea. Congrats on launching!

In my case, I actually did think of this idea! Just never had the hardware knowledge to even know where to get started (and I was worried about the trouble it'd cause as card skimmers used it to easily clone cards - hopefully we'll learn more about how coin solves that problem). I'm mostly glad they're trying to make this a reality, because I'd really like to get rid of all these membership/point cards that stuff up my wallet.

With any luck, this will piss off the banks/CC companies enough to finally roll out chip+pin in the US.
