[QUOTE=J!NX;42889668]whoa its almost like that should just be common fucking sense
3 or 4 cards seems like a top for me but... Jesus :v:[/QUOTE]
There are reasons people get so many CC's, I think.
"One Coin to rule them all.."
whoaaaaa so much wallet filling ughhh I can't handle this horrible struggle god please bless me with a revolutionary device so I can bear this immense burden no longer
that shit is gay I don't want a bluetooth iphone app smartphone googee gadget to wipe my balls and display alarm clock digits
In my state (Ohio) absolutely everything uses magnetic stripes.
It's annoying to use multiple cards but I don't complain much
Mobil Card - Gas (8%)
Bank Card - Regular Purchases (90%)
Credit Card - Purchase I have to do but really can't afford right now (2%)
aka, I only use two cards 98% of the time.
why not just use nfc and google wallet or something
it's pretty much the same exact thing

anywhere there's nfc it's supported.
all the local fast food places where i live have them for example
[QUOTE=be;42887101]like?[/QUOTE]
What if the waiter accidentally presses the button to switch cards. How easy it is to add someone else's card. From the posts above, some places don't support cards like this.

Really you should always be using your credit card, even if you can afford it (especially if you can afford it). It'll get your credit score up, and as long as you pay it off at the end of the month, no big deal.
[QUOTE=ac/14;42886564]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.[/QUOTE]
The new bluetooth 4.0 low energy standard can run on a coin cell battery for around a year before it depletes, and that's with having a connection and transferring data for 1 second every minute.
Yes, I totally want my method of payment tied down to something that requires a battery.

Um...why is that a problem? Your cellphone requires a battery and it can save your life in many situations, your car requires a battery and it's among the most useful things in existence.
Charge it, lol.
Fucking people, why are you guys against this? You're just finding stupid reasons to hate on this invention for really no reason besides because you can.
[QUOTE=Downsider;42888090]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]
Encryption aside, a magstripe requires you to actually have the card in order to dump it whereas with RFID you can hide your harvester in a briefcase, walk through a train station and read off anyone who is in proximity.
So if you're able to scan your cards into the phone thing, to add them to your 'Coin'...
...What happens if you scan a 'Coin' card?
I really dislike the name, btw. Just call it something distinct, not an actual damn word. It's another one of those products where the name confuses everyone.
I would not pay for a "coin" when I have had no issue carrying cards around. I have my wallet everywhere I go, it holds more than enough cards. Maybe if I for some reason had to carry 8-9 cards it would be useful, but I dont need that many.
I imagine that this might make identity theft a little easier because with someones info it would be easier to make a fake card without worrying if your copy holds up to scrutiny. Just load up a standard blank with the data you stole and scan it in.

Unless you have a wallet that doubles as a faraday cage.
The bluetooth thing is the only thing security wise? for something containing that much data it doesn't seem very safe against thieving, and the only security feature is one that only accommodates you if you leave it behind, which isn't the only way to lose your stuff

So you're just going to choose to ignore the security features that make it vastly preferable? You can harvest all the useless data you want if you really want to. It's not like some time-efficient way to get around asymmetric cryptography is going to be found out any time soon, or at all.

Last I saw, RFID solutions like PayPass didn't use a lot of magic. Skim the card and you can use that data to make a transaction on a clone card at least once. It's not how well the data is encrypted that can make it secure. It can also be how hard it is to [i]reach[/i] the contents of the card. Saying that it's secure because it's encrypted can be fatally narrow-minded.
Example: When Shell still used EasyPay I was able to clone my dad's fob in less than two minutes. Nobody would of ever noticed it was skimmed either unless I went into the gas station to make the transaction there.

How many people actually buy wallets or purses and take the time to check if it's designed for holding RFID cards? Not everyone is tech aware.

Just because there's implementations that suck doesn't mean the technology isn't sound. RFID-based "smart cards" are the best solution. It's more secure if it's designed correctly, and I'm sure there will be regulations on it.

Just use a goddamn smart card, period.

Just going to dispel this whole Bluetooth thing, it's using Bluetooth 4.0 Low Energy which typically uses 20 to 100 times less energy than conventional Bluetooth during operation, and even less when it's in standby. Using a coin cell would probably get you a life of 2-3 years.
4.0 is also encrypted with 128-bit AES, so its more than secure.

[quote="Wikipedia's article on SMART CARD']A smart card, chip card, or integrated circuit card (ICC) is any pocket-sized card with embedded integrated circuits. Smart cards are made of plastic, generally polyvinyl chloride, but sometimes polyethylene terephthalate based polyesters, acrylonitrile butadiene styrene or polycarbonate. Since April 2009, a Japanese company has manufactured reusable financial smart cards made from paper.[1]
Smart cards can provide identification, authentication, data storage and application processing.[2] Smart cards may provide strong security authentication for single sign-on (SSO) within large organizations[/quote]
I'm not referring to the wireless ones.

You're underestimating the power of asymmetric encryption, though.. It's not like other types of encryption. Even with it going over the air, it's thousands of times more secure than storing a dumb value on a magnetic strip.
Maybe im lacking here because im in the US, but all my cards use a mag stripe. Not a single one doesnt have it. COIN is a cool idea, but I dont know how it prevents others from choosing which card to charge when they take it from your table etc
Magnetic strips are slowly being replaced with smart chip technology in Australia, my driver licence for Queensland has a smart chip on the side so police can scan and bring up all my records in a secure database
If you get a new card from your bank, you have a smart chip on it, most stores here now include combo readers that use both magnetic tape and smart chips because not everyone has made the switch, my card is still magnetic but it'll change soon
I like the idea but this is obsolete already, use something like paywave even though its not really trustworthy but still
