Interesting idea. That bluetooth thing will eat battery though. How do you charge the coin card? Can it be wiped? Why does it need some phone app? Too many questions for me.
How would it work in the UK since everything is Chip and Pin based, if it worked in the UK I would be tempted since I have loads of cards all over the place
I'm assuming the card data is copied from the magnetic strip (using the gizmo plugged into your smartphone) then copied onto the Coin from your smartphone via Bluetooth. Then a special chip replicates the data in a card reader depending on which card you have selected.
No Windows app yet. WHELP

Yes, at once. [editline]17th November 2013[/editline] Well. The point is that if this doesn't take off completely, that will be the result. And what are the chances that this will take off completely?
I don't think its really a standard as it is somehow taking the magnetic data from the card and replicating it on demand. its just consolidating your cards.
All Canadian banks have enforced that by next year you won't be able to swipe your cards at all in favor the more secure smart chip technology. This is obsolete before it even makes enough kickstarter money.
I like the idea, just has a few issues.

I'll never take off unless they call it a Credit Chip
what if you take someone's card and swipe it in, effectively making a copy of it?

almost nowhere uses the magnetic strip here anymore

How is this better than BTC ?

This is so bad counter fraud wise, I can't see a future in this
[QUOTE=Ithon;42887548]you can put another wifi chip in coin, however it's still flawed from easily being hacked.[/QUOTE] RFID is even less secure than a magstripe.
People still use magnetic strip? v:v:v
[QUOTE=wanksta11;42887850]How is this better than BTC ?[/QUOTE] How is this even comparable?
[QUOTE=pentium;42887875]RFID is even less secure than a magstripe.[/QUOTE] Uh, no. RFID can literally use asymmetric encryption ala SSL because you can embed a microprocessor and have a handshake via RF, transmitting any sensitive data. Magnetic swipe cards are just swiped and store a dumb value that can very easily be cloned. RFID-based smart cards COULD be just as insecure as a magswipe, or even more because it's wireless, BUT if they correctly implement asymmetric encryption, which is still considered completely unbreakable and is what SSL uses, then it's literally unbreakable by today's standards. Conversely, a mag swipe card can be cloned with less than a hundred bucks worth of equipment and a little basic knowledge.
[QUOTE=be;42887101]like?[/QUOTE] Your phone says that you left your card, but it won't really be effective at helping you find it. They can push the button to charge whatever, either on purpose or by accident which could get you in trouble. If it gets stolen, you now have 15 different cards that are all stolen, instead of one or the few you keep in your wallet.

Not a problem, a regular card wouldn't even be able to tell you that you have left it, let alone tell you where it is. 2. That's a software thing, I'm sure there'll be the ability to put a password so that you can only switch between cards if you input a password, and it would otherwise lock the selected card into place 3. Security code. I don't know if Coin has a security code option n shit, but I don't know why they'd make a credit card thingie without a form of security like that.
Well sucks to be me for not having a smart phone. Looks like This wouldn't be useful to me.
imagine how screwed you would be if that got stolen.
I got a better solution: don't get so many fucking cards in the first place :v:
[QUOTE=Kegan;42889651]I got a better solution: don't get so many fucking cards in the first place :v:[/QUOTE] whoa its almost like that should just be common fucking sense 3 or 4 cards seems like a top for me but...
