Geode Turns iPhone Into Universal Credit Card Rewriter

I never thought I’d get excited about boring credit cards, but Geode is an incredibly neat little kit which turns your iPhone into a payment system that can be used anywhere. And not some fancy NFC-style POS terminals, either. The Geode works anywhere you can use a regular credit card.

The kit contains three main parts, plus an app. First is the case, into which your iPhone slips. The second is a detachable card reader, and the third is a reprogrammable credit card which lives in the back of the iPhone case.

To use it, you scan your cards into your phone by swiping them through the reader, and then toss the reader into a drawer or whatever. Then, when you want to use a card, select it in the app and its details are written to the card. Use the card just like any other credit card, even in chip-and-PIN machines.

As if that wasn’t clever enough, you can also scan the barcodes of your store loyalty cards and they are displayed on an e-ink screen on the back of the case, readable by any in-store scanner.

Finally, the app is protected by a fingerprint reader on the front of the case, so that if you lose your phone, the finder won’t get access to all your cards.

If you want one, you’ll have to drag out your tired old credit card and pitch $150 to Kickstarter, where the project has already achieved funding. If you decide to wait for it to go on general sale, it’ll cost you $200. That’s a small price to pay for the chance to leave two or three credit cards at home and replace them with a harder to use and slightly larger iPhone case.

    Credit Card hackers and cloners, rejoice. What if I scan someone else’s card? And, who’s gonna accept some hackety hacky black card with no signs on it as a payment method? I know I wouldn’t….

    As soon as a new iPhone comes into your life, you’ll be screwed when it doesn’t fit or is incompatible… Run out of battery, run out of money, lol!

    They say on the kickstarter page that it isn’t possible. I dunno how
    they prevent it, but they say it’s built-in. The only question I have on
    that is what if you have permission to use someone else’s card? Can you
    import that? Don’t know…

    How do you charge the phone?

    Without a lot more details about their security procedures, I’d assume this is a big liability in your pocket. I’d urge iCache to use some of that Kickstarter surplus to get some 3rd party validation on their security. 

    There is a lot of room for abuse from where I sit. This thing is storing track data (should never be stored, according to payment brands) and the CVV/CVC2 codes which are never supposed to exist except on the physical card. That’s the whole point of the security codes – they are supposed to prove you have physical possession of the card. I understand the product aims to “replace” your cards, but the payment brands (VISA, MC, DISC, AMEX, JCB) have final say where that is concerned.

    At a minimum, this needs cryptographer, mobile device security expert and payment brand blessings before I’d be comfortable recommending it, cool as the device is…
