Casio's Credit Card Watch 142

Posted by michael from the calculator-watches-suddenly-uncool dept.
Takuryu writes "Casio, working with Japanese credit card company, JCB, has developed a combination credit card wristwatch. Workers at the main JCB office wear the RFID tagged watches and use them for security access at the office, as well as for paying for lunch in the cafeteria. I wonder what percentage of employees they have tagged?"

    We all know what's going to be said. The watch is easily stolen. Has been for years and years. That's what makes it so appealing to criminals. This isn't going to catch on and for good reason. The security on these devices sounds like nothing at all.

      And what's the security on your regular plastic credit card? That there's a non-verifiable signature on it that most merchants never check? That sometimes, for an online sale, the merchant asks you to turn over the card and input that 3-4 number code on the back?

      If anybody ever gets physical access to your stuff, it's pretty much always game-over. Doesn't matter if it's your wallet, cc-watch, speedpass, or whatever you use.

      • But with a card, you can usually tell whether or not somebody has physical access to it. Sure, the waiter could copy the number, but at least you know you gave it to him. With an RFID device, a reader could conceivably grab your number while you were just walking down the street.
        • Good thing there is such a device as a passive RFID chip, where the VCC is powered via inductive coupling with the chip itself. The range can be "configured" to be quite small - thus you are safe. The scary thing is the credit card receipt copy that the merchant keep that actually contain your number and expiry date!

            No, you are not. No matter how small the range, you can still get scanned in public places like crowded buses and other transportation as well as theaters, shopping malls, events with crowded people, or even while standing in line. The difference is that a thief does not have to pick your pocket. The thing should definitely have an on/off switch; except that that's not how most, if not all, passive RFID chips work.

            The scary thing is the credit card receipt copy that the merchant keep that actually contain your number and expiry date!

            That is why most relatively new credit card processing machines do not print the credit card number (maybe only last 4 digits) or an expiry date on the receipt. Obviously, manual processing of the credit card is not as "safe."
      • And don't forget this point:

        If you lose your watch, or if it gets stolen... chances are, the crook won't realise there's credit card information *in it*. There'll be a pretty good chance they'll think it's any other watch. Unless it says "CREDIT CARD WATCH" on the wristband...

        That's a good point.

      The usual procedure after a theft of one's smart card is to cancel that particular card, just as one would cancel a credit card. However, since most smart cards are debit-based systems, there might not be any theft protection limit like that in regular credit cards (where the cardholder is responsible for $50, then the rest is taken care of by the company).

      Since this is a credit card watch, I suppose the credit card company would treat it as regular card. In that case, the only reason that this would be a bad idea is that it most likely won't have the cardholder's signature on it for verification purposes, making it easier for the thief to use the card. Most clerks in America don't bother to check the signature anyway, so I don't see this as much of a problem.

      The watch is easily stolen. Has been for years and years. That's what makes it so appealing to criminals.

      If you're saying that it's just easy to steal a watch that is in plain view, I'd say that it's mostly expected that people carry around wallets and cell phones, so it doesn't make a thief more likely to rob a person wearing a watch. Unless, of course, they target people wearing fancy-looking watches. In that case, the ugly plastic quartz watch in the article will have the unexpected benefit of deterring thieves.

      • "paying lunch in cafeteria" sounds just like some system like at spa's where they just get the number from the changing room key and bill you later(from your salary probably in this case, at spa's they bill you when you leave).

        It's just a very easy and convinient(and a bit more trusty) way of saying your account number to the clerk..

        it doesn't bring in any new problems(old style visa credit cards are very easily copied, in fact, you just need the numbers anyways so you can just copy them without stealing
      • The possiblity of fraud -after- the card is cancelled isn't possible in electronic transactions. This one doesn't allow any other kind.
        It would be nice if it stopped working as a watch once identified as cancelled.
    • It's a lot harder to lift a pocketwatch off someone walking down the road than it is to lift someone's wallet out of their back pocket. It takes much more sill, and thus the number of crooks you run into who could get away with it would be smaller.

      Also, it would be relatively easy to include on the back of the watch a small thermal sensor. When you put the watch on in the morning, it asks for your PIN to activate the RFID credit card. Then, if the watches thermal sensor ever detects that it is off the skin

It doesnt store the credit card number, but a unique ID that when I pump gas, it will read the number and charge the account associated with it. I would hope these work the same way. Kind of like how the PIN number for your debit card isn't actually stored on the magnetic strip of the card.

        It's a number which, if transmitted in the proper format, will allow access to your credit. Thus, it is a credit card number for all intents and purposes. That it's a different number than the one printed on your old fashioned card doesn't matter.
        • And I might add that anyone fairly skilled in electronics design can build a decently long-range RFID reader/retransmitter, so why anyone would rely on something RFID based for anything remotely sensitive is far beyond me. I would think the only even remotely secure way of doing this would be to use something like bluetooth with an encrypted number and rotating key scheme or something. This would at least be marginally harder to crack.

          If your petrol station reads a unique ID that *isn't * your credit card number off the card, and hands it off to the bank, it's far easier to check that card 0144829 (belonging to Patrick Martin) was scanned by reader 2841 (pump 4) at retailer 22019 (Esso Canniesburn Road, G61 ???). Now, since the credit authorisation bureau know that Esso are allowed to accept your card, that's great, it works. If J Random Crook gets hold of the number he would also have to spoof the reader and store

          • So, we apply a little bit of public-key encryption, and it makes it pretty much impossible.
            The problem with RFID is that is is a passive device(it just coughs up the info whenever it's asked), thus it cannot encrypt info with the gas station's public key. Now the ID itself could be encrytped with a public key of the user, but that does nothing to stop "replay' attacks, ie the attacker "records" the id and replays it whenever he wants to charge something to the account(obviously he can only use it in plac

The customer has an illusion of security, and the credit card company increases its profits. Everyone's a winner.
    • The worry is that someone will set up a scanner in a vending machine and rob people who walk by. I'm not sure how these things will practically work, especially if everything has an RFID tag in it. A scammer can collect all the numbers it can and try them out one at a time. The legitimate vendor has the same problem. It will be creepy enough to have the billboard recognize you by the RFID in your shoes.

    • Even if an RFID version of the watch was made, they could use the "weaker" type of RFID that can only be read within shorter distances. My guess is that the FeliCa IC chip used by the watch mentioned in the article doesn't actually give out the credit card number ever.
    • I bet they don't carry CC numbers as such. It's just that the guy files a paper with his CC number when acquiring the watch, then at the cafe the barman just presses "cash from RFID" and the watch ID gets associated with CC# in the company database and charge the card for the purchase. Anyone without access to the cash register won't have any use for the ID unless they manage to rebuild just the same kind of chip.

    I was under the impression this has been available in America for quite some time from Timex. [timex.com] and Exxon.

    Granted Speedpass isn't accepted everywhere by any means but gas and nowadays many McDonalds and a few supermarkets (in certain areas.)

    The standard unit is small enough to just ditch the keychain and tuck the bead in my wallet; in fact with a bit of crazy glue I'm sure I could turn anything into a credit card of sorts. Since Mobil gives them away free (no fees, just a draw to their places) the tech must be cheap as hell- little more than an inductor/antenna and a simple IC with a serial number... it's basically less circuitry than a typical disposable camera, and far less than a digital watch.

    Imagine the day when RFID tags are so common every coke bottle has one. Now cut them off and pack, say, 1000 or more int a match box. Carry them with you at all times. A reader sends a request and gets 1000 replies. 1000 not enough? Get 10.000. I wonder how many replies the reader would be able to handle simultaneously and how efficiently the chips could jam each other.
  • From the article Casio is very big on the fact that you now don't have to root around in your bag for a credit card or cellphone in order to pay for things or get in and out of the office.

    It would also appear that Casio are very big on conveniently ignoring the fact that this isn't anything new. The Hong Kong public transport system has been running on an RFID card called 'Octopus' [octopus.com.hk] for several years now. I've used it lots of times, and it works really really well. The Octopus system used a credit-card sized card [octopus.com.hk] with an embedded RFID chip by default, but there are also wristwatches [octopus.com.hk] and wear-around-your-neck-on-a-lanyard-watches [octopuscards.com] that perform the same function.

    You can pay for bus and train (MTR) [mtr.com.hk] trips using the Octopus card, make purchases at 7-Eleven [7-eleven.com.hk], and top up the card at railway stations and 7-Elevens, and make purchases from an increasing array of other stores, vending machines, parking, ferries, cabs, supermarkets, even school tuck shops!!! [octopuscards.com]. The system works really really well - despite the potential privacy issues, I'm a BIG fan of HK's Octopus.

    The system is, by default, largely anonymous. There's nothing to stop them putting a camera near a reader I guess, but I've never been asked to prove who I am when purchasing an Octopus card. The company acknowledges customer fears in respect of anonimity in various ways, they offer a 'personalised' octopus card with your photo on it if you want it, but there doesn't seem to be any pressure to adopt the personalised version.

    Clearly, it would be trivial to extend the Octopus system to access control. In fact, it wouldn't actually require any 'extension' of the system, just get your own RFID readers that speak the same frequencies and 'language' as Octopus uses (RFID is still very 'unstandardised', there's a lot of 'standards' to choose from), and make them respond appropriately to the unique IDs in the Octopus cards/watches you happen to own.

    I'm from Australia. A friend of mine is sending me my first Octopus watch next week. I already have a handfull of Octopus *cards* here to play with. Where can I get the RFID kit I wonder!

    I worked for a firm that used Javacards to do a simliar thing. You set a debit limit via the intranet, and your food, gym, purchases and the car valet were all taken from your wages each time you swiped.

    It came off gross too, for great tax efficiency, plus no banking details were ever transmitted.

    Administrators could call the lift (elevator) when they swiped in to work in the morning :)

    If you take a look at Timex [timex.com] you will see the new line of speedpass enabled watches. This means that when I mug someone I can just get their watches - (which gives me the credit card and spedpass for US gas stations!!!)
    Rock On!!


  • Credit cards used to expire in 5 years. Now all of mine expire in 2 years. Whatever. 5 years, 2 years, that's still longer than my last Casio watch lasted. I don't think I'm particulary harsh on watches, especially because there are others I've had for more than 10 years. I just not sure I want my credit card number blinking 0000 0000 0000 0000 000 after 6 months.

  • Signature experts? (Score:2, Interesting)

    I read several comments about how most cashiers don't even check the signatures.

    I always get a big laugh when one of them does check the signature. Why would management think that a cashier that can't make change if the cash register is down is suddenly a signature expert when someone uses a credit card?

    Several years ago one of the news magazine shows on TV did a story where they took some of those credit cards with the people's pictures on them and gave them to staffers and sent them into stores in
    • I don't think that this is a big conspiracy by the big corporations and there are many websites and books out there about the tricks of the trades of credit card companies, but most people don't read them just as they don't read MS EULAs.

      As for the debit card, Visa announced that they will have similar fraud protection against unauthorized charges against the debit card as they do for the credit cards.
  • anyone remember that? Whatever happened to the Java Ring and why haven't firms adopted it yet?

    It could open security doors, etc.
