Could I put all my credit cards in a Wallaby Card, and then put my Wallaby (and debit and reward cards) on a Coin Card? If so, I'd have just one card (Coin's pain point), but I'd also get Wallaby's "smart routing" for miles (Wallaby's pain point).
Even better, get the Loop case for your phone and carry zero cards. It emulates the signal the reader would get from a magswipe wirelessly, so you just hold your phone near the reader. It's supposed to work with credit/debit/loyalty cards like Coin and is shipping soon, not next year.
Well technically the part that allows you to pay is shipping next year...
Also this doesn't solve the problem that is being discussed in the coin thread of imprinting and buyer verification for the merchant.
Still, This is the technology that cell phones should be including on a hardware level, not the stupid NFC thing that doesn't work for most US POS. I don't have an iphone or else I'd be contacting them right now asking if I could get in on the action even though I'm about a week late!
What they should do is connect your cellphone account to this and that would allow the carrier verify your identity (if you're on a contract).... I'm sure there's more here that we could do, maybe have an option to silkscreen the your id of choice on to the back of the case...
People this needs to be made to work NOW!! I use the ninja wallet and even that is too big and bulky for me, if I could get rid of the whole thing and just carry it in my phone the world would be a better place!
How so? It's extremely short range, the only thing that can read it is the terminal you were about to give your card to anyway. It's not broadcasting while in your pocket, so nobody's going to read your card by bumping into you.
