Many credit card companies are starting to issue new cards which are completely flat, making it impossible to make imprint. My new CapitalOne card is an example of this. Is your company planning on refusing to do business with them?

My Discover Card is like this as well. Totally flat, no ability to imprint.

From this thread I learned that there was some purpose to making in not flat. It's even sillier than the credit card itself.

This will never catch on in Australia unless they can clone paypass/paywave. Now most of our transactions are contact free with chip and pin as an option for large purchases.

Just having to enter a pin in Australia is going backwards.

At Whole Foods they often want to see the back of the card to see the signature if the purchase amount is over $100. They most had gotten burned sometime in the past because I go to this Whole Foods in my home town at least 2/3 times a week and the checkout clerks know me and my wife but they still insist because sometimes we use different credit cards.

Imprint was just an example. You can take a picture of it, view the CVC, etc. No one imprints anymore.

Not true a lot of small mom and pop stores who are not that electrically savvy still do take an imprint.

I don't know why the US hasn't adopted EMV. It's not perfect, but it has cut down fraud massively here in Europe. They're very hard to clone (I won't say impossible, but attacks against EMV have not generally been of this nature) and the transaction records at both ends will tell you whether the actual, real card was there. The liability is more clear-cut as a result. If the customer claims the charge was unauthorise…

In Australia, we've even moved beyond EMV; the majority of merchants now accept Visa PayWave and MasterCard PayPass for tap-and-go. [edit: Oh, and all my debit/credit cards are now paywave/paypass enabled, and they are all from the big 4/5 banks] The Coin page doesn't mention this at all; does it have this? If not, it sounds like a step backwards.

I'll let you in on a little secret - paywave/paypass etc are EMV cards. The interface is wireless and they have a shorter transaction flow. There are less (zero) customer validation techniques, final evaluation (pass/fail) takes place at the stage a 'normal' EMV transaction would decide on pass/online/fail.

As usual there are variations between implementations, but underneath it's all good-ol' EMV :)

So I doubt that these could be supported easily by Coin, it requires various keys that the banks do not allow to escape.

If Coin do manage to get talking to banks about allowing wired or wireless EMV apps to be loaded onto a customer Coin card then that would be awesome. I predict that layers of bureaucracy and brand-management will prevent this.

But good luck to 'em if they try!

EMV where you need to input a PIN Number is simply a way for VISA/MC to push all the liability onto the customers for stolen credit cards. If a purchase is made with the credit card and PIN, then the issuing bank can simply let the liability fall on the customer, instead of the bank eating the costs, like how it's done today.

Merchants eat the costs where no EMV card was used. Customers eat some costs where the bank can prove negligence, and face court if the bank can prove fraud (i.e. signed statement it wasn't you but later the CCTV footage is found. Oops)

Other than that, here in Europe, customers are protected by law from having to take on the liability. Varies by country, but basically it's a case of "you're responsible to see that nobody else gets to take my money, that's why you're a bank numbnuts"

Don't know if your personal card is an Amex or not, but my Amex is a Costco Amex and doubles as my membership card. I'm surprised your loyalty cards aren't the smaller key ring ones. I have half a dozen on my keys and barely notice them. I leave my AAA and Airline cards at home and pull them out when I need them for trips. Could probably do the same for your Zip Car card (unless you use the service multiple times a w…

The problem is any time you edit some of them out, you realize soon after that you don't have the one you need. If I don't carry around the cards I will need every day, I am likely to forget to take the ones I need only occasionally when I do need them. The problem is that Coin doesn't really solve this. It only encodes credit cards; most of the other cards either don't have mag stripes or require other information o…

That happens to me all the time with my airline club cards. I always get to the airport and realize I forgot them.

Nice execution. I saw several pitches for unifying cards while working for a VC.

As a consumer I have a few suggestions:

1. Make the card switch/activation button detect the fingerprint of the owner. (The merchant or waiter sliding the card could press the button accidentally and switch to a different card)

2. Show me that a tap-scanning tool can't take the data for all of my cards. (from hackers to accidental taps)

3. Can a magnet disable this card?

4. What happens if someone steals my coin? Can I disable it remotely with the app? Can it happen automatically?

Good luck!

I think in your scenario, a good fit would be a cigarette case that you'd keep in your front pocket. I'd love to have one with a classy finish and that would block NFC signals from leaking. I ended up ditching all but essential cards and got down to five. One debit, credit, health insurance, license, and AAA.

I'm American and I never understood the back-pocket thing until I moved to the West Coast and started carrying my (bulky, remote) car key in addition to just house keys. Once you have those and a phone in your front pockets, something has to go in your back pocket.

I paid with cash in the end :) A+, would do again.

amex cards all have chip versions that you can request for free

Have the chip version of the Amex Platinum. Since its the US version, its chip and signature, not chip and pin, and works almost nowhere in Europe.
