RFID Tags on Mach3 Razorblades Snap Your Photo

peteo writes "Think RFID tags are harmless? Look at how they are being used in the UK: "At the Tesco Cambridge store, a camera trained on the Gillette blade shelf, and triggered by RFID tags, captures a photo of each customer who removes a Mach3 pack. Another photo is taken at the checkout and security staff compare the two images to ensure they always have a pair" According to the spokesman,"there are certainly not any privacy concerns" in relation to these tags. He adds that there is plenty of in-store signage indicating the supermarket's use of CCTV cameras. ""

    Tin foil hat privacy issues aside, the reason for this is because Gilette Mach 3 Razor Blades are the most shoplifted item in Britain. This is due to Gilette's "strategy" of giving away the razors and charging through the nose for the blades.

    Am I the only person who changes his mind when he's at a shop, and occasionally puts something back?

    Is everyone who picks something up, decides they prefer to get a 12 pack, or the cheap disposable, or whatever, going to get investigated by the police?

      Not unless you maul the package, take out the rfid chip, and hide it in your sock. If you put it back, the store knows, because hey look, the 8 pack of blades just showed up back in stock. If you put it down elsewhere, the RFID reader at the door never sees it leave, so it never sounds the alarm.

      Besides, it won't be long before they can track items anywhere in the store with RFID, at which point when you put your 8 pack of blades in with the potato chips, they'll send a stock boy out to put 'em back.

      That is the same problem as hotel automated mini-bars, and one of the long standing ob electronic people jokes - removing all the items from the minibar then putting them all back.

      Needless to say its very hard for the manager to explain the automated bar bill that appears as a result.

      The police aren't the only problem with RFID though. If I have the RFID data for a range of products I can do several things that favour the criminal - consider a mugger sitting with a PDA zapping people going past and getting valuations on them..

      Suddently splitting up and asking your significant other to pick something up for you in a different part of a store warrants a crime.

      The thing is, it doesn't. If they build a technical mechanism to catch shoplifters and that mechanism isn't reliable, it's not your problem. "Crime" is a concept defined by law, not technology.

      Sure, they might not want to give you this impression, but it's their responsibility to prove that you are guilty of something and if their technology can't give enough proof, the technology is nothing more but a way to scare people. Picking something from a shelf may be proof in some cases, in some cases it isn't.

      If you know that you've not stolen anything (which should be rather easy to know...), stand up for your rights if you're accused of something.

      Yeah, because people are never wrongfully accused, or convicted, based on incomplete or even entirely false evidence.

      Personally, I can't afford the legal fees I'd need just to be able to shop in the UK. I take things off shelves all the time and put them back in the wrong place.

  5. Simple solution by BabyDave · · Score: 5, Insightful

    When you go shopping, always have an accomplice - (s)he picks up the blades, hands them to you somewhere else in the store, and you take them to the checkout.

    Of course, this would happen 'accidentally' quite often anyway, but it's always good to make more trouble for stupid schemes like this.

    [This trial] is not to do with security or theft, it is a supply chain trial."

    But they then say security staff use it. So what is it for? What supply chain information does it give them that they can't get from the till receipts?

    My local supermarket (Safeways, Shepherds Bush) had huge shoplifting problems with razor blades. Rather than implementing this (presumably expensive) scheme, they took the simple step of moving the blades behind the counter at the store pharmacy. Shoplifting drops overnight, no added cost and no privacy concerns.

    It is totally outrageous. Talk about a monopoly!

    Of course, these statements are essentially contradictory. Obviously Gillette does not have a monopoly, because there exist alternatives. They apparently offer a superior product, but at a higher cost. The whole point of the free market is, you get to choose what you pay for. If the cheaper blades were as good, people would move to that system and Gillette's price would come down.


    Are you alleging that Gillette somehow uses its market presence to squeeze out the other players?


    Not every high price indicates the boogey-man of "monopoly". Higher quality sometimes demands higher price.

  10. As little added value as possible by panurge · · Score: 3, Insightful
    Of course, this arises because supermarkets try to create as little added value as possible. They hire expensive psychologists who tell them that because we are basically hunter/gatherers, we can be conned into pushing the trolleys round the store and collecting the goods ourselves without realising that we are doing all the work, being exposed to all the advertising and subtle pressure to buy, and they are getting all the money. So, rather than prevent theft by the traditional means (sell things from behind the counter on request) they decide to try RFID - which we pay for - so we can have our privacy invaded at our expense.

    Possibly - here, they're demonstrating the ability to link your identity with what you buy, and fairly automatically, en masse. Potentially, this could allow the authorities to track practically every "new" object you bought.

    Um... Most of the major supermarket chains in the UK, including Tesco and Sainsburys, have a "loyalty card" scheme that allows them to do just that, in exchange for a small discount on your shopping. These are used to target advertising, adjust product lines according to customer demand, etc. They don't tell you in as many words that this is what the cards are for, but everyone with an ounce of brain matter knows it, no-one really makes a secret of it at the stores, and it seems the vast majority of their customers voluntarily get such a card, supplying the required information in exchange for a discount.

    So yes, they can theoretically track every new purchase you make, as long as you use the card with it. That's the whole point. If you don't like that, don't get the card, but the vast majority of people don't seem to care.

    I'm curious to know what they gain by this arrangement, though. There are already scanners on the door at that Tesco (my local branch, half a mile from my home) that are supposed to detect anyone walking out with security tagged goods that haven't been paid for, and a security guard by the door. (The same is true of pretty much every major supermarket over here, and most high street clothing stores etc. where there's a big risk of theft.) What does this gain them, a picture if someone manages to get through the alarmed section and past the guard without setting them off? In that case, what if someone else picked up the tagged item, got photographed, and then replaced it on the shelf, prior to a second person stealing them? Oo-er, doesn't sound promising. Maybe I'll just buy my razors from Sainsburys (the other big supermarket, half a mile in the other direction) instead...
