Walmart to Push RFID 497

bravehamster writes "According to this article over at MSNBC, Walmart is going to push its suppliers to start using RFID to track inventory by 2005. The article goes on to mention how it was Walmart who helped jumpstart widespread adoption of barcodes. The report also points out some of the barriers in the way of RFID acceptance, but never once mentions consumer privacy concerns. Guess that kind of stuff just isn't important anymore."

    I don't see why this should be so difficult. I mean, they do it today with a big magnet for shoplifting purposes, why can't you make an RFID tag that deactivates when placed over a big magnetic field? This way there's no need to worry about privacy and Walmart gets a way to save money by using technology that already exists in all their stores anyway.

    Two questions regarding RFIDs:
    1. Once you take a product home, what's the cheapest and most convenient way of detecting an RFID tag? Is there any consumer-level equipment available to help with this without complication?
    2. Once a consumer discovers an RFID tag, is there an easy and convenient way for this tag be destroyed without damaging the product in any way?

    This technology can be revolutionary for maximizing the efficiency of the supply lines of very large companies such as Wal-Mart. However, the only real way to relieve privacy concerns is to come up with some way for the chip to PERMANENTLY disable itself when the item is purchased, in such a way that it is physically impossible to re-activate the device.

    I don't think this will be done, however. What is more likely is some sort of software "de-activation" that will make consumers happy but will not necessarily be a true solution, in that it will be, at least theoretically, possible to re-activate the device.

    RFID tags are a great idea, but the potential for abuse by data miners is simply too great-- greedy companies will be tripping over each other to collect data about you and sell it to other companies who want to advertise shit to you.

    RFID tags in merchandise are only half of the equation-- the marketers need a way to attach that data to a specific person-- like if some state gets the bright idea to embed an RFID tag in its driver's licenses. Or if a credit card company puts one in your VISA or MasterCard. Then...

    Bingo. Joe Blow walks through a doorway, and and any still-active RFID tags on his person are collected by the RFID tag reader built unobtrusively into the door frame. Some computer in the back room duly records that Joe Blow has a NJ driver's license, wears Lee Jeans, Hanes boxers, Reebok sneakers, and chews Big Red.

    RFIDs have the potential to be an excellent inventory tracking device but as this discussion has brought to light there are many issues regarding privacy the public is still concerned about. Rather than let suppliers come to grips with these issues over time Walmart has flexed its buying power over its suppliers and will force them to do what THEY want regardless of what the public or these supply companies believe. I work in the manufacturing sector and I have seen Walmart do this all to many times. For example, Walmart more often then not will force a company like Black and Decker or Eureka to produce a model just for them that fits Walmart's ideal price no matter how much the quality of the product will be affected. I just want to point out that although this article portraits Walmart as a champion of technolgy with this move, IMHO their bullying is not fair or just....

    • We didn't really lose privacy, and it made inventorying a lot simpler.

    Well, yes... If you don't count that fact that stores keep track of every item you ever purchase, then no, there was no loss of privacy at all.

    • So someone can query you wirelessly and find out what you bought - big f'ing deal!

    I think the idea was that people could track what you purchased after you left the store, which is a bit more insidious.

    Maybe you're just being sarcastic. If so, it's too subtle for me.

    Paying with a credit card is a choice the consumer makes. If some people are worried about a database tracking their purchases, at least they have the option to use cash. But with RFID, customers have no such option. Everyone can be tracked, regardless of whether they approve or not.

    Why? These are IDs. I do not see what information they contain that you would be concerned about. they are not recording devices. I do not see any additional privacy concerns beyond what we have with store "savings/check cashing" cards and barcodes already.

    I don't recall anyone with a cadilliac or other high end luxury car, or other passive anti theft car with the RFID tag in the key, concerned about privacy.

    I don't recall any dolphins or sharks complaining about the RFID tag on their fins.

    Are the RFIDs on products plain serial numbers without meaning, or do they contain information about the product? Would it be worthwile to by a handheld RFID reader and scan for fun stuff in crowded places, e.g., recently bought:
    • pregnancy tests
    • sex toys, porn and lubricant
    • medication for embarassing illnesses
    • guns
    Any other suggestions? ;-)
  • by Anonymous Coward on Saturday June 07, 2003 @01:12AM (#6137425)
    Well, this is different. Neat features of RFID tags:

    1. Can be scanned from a short distance.
    2. Virtually unlimit ID pool, every one ever made can be uniquly identified.
    3. Not tide to a scanner, any one with an RFID scanner can track them. Even the bad guys.
    4. Once everything has a tag installed, congress can be lobbied to make removing them illegal, or embedded in drivers licenses, etc.
    5. Airports, bus stations, side walks, grocery stores can be equipped with scanners. Since eveything you wear, your shoes, your wallet, your watch, that clean pair of socks, has a chip in it you leave a trail where ever you go.

    Cool trick: Bought a soda at the corner store? The store scanned your sunglasses when you came in and scanned your sun glasses and the soda when you left. Now you throw out that soda, and it leaves evidence you where present.

    Another cool trick: You give 5$ to a friend for a six pack of beer. He doesn't get scanned and associated with the 5$ bill, and uses it to buy drugs. The cops nab the drug dealer with the 5$ bill and start back tracking where it's been. You're the last person scanned with it, they start asking questions....

    With a large enough cloud of RFID scanners one could, in theory, track hundreds of people moving through a busy street in Manhattan. By grouping clouds of RFID tags together you could track the individual exchanges of goods between people in near realtime on a mass scale. It would make for a really cool web page.

    RFID tags are cheap, they're not indistructable nodes, but any given person could have several on his personage with out even knowing it. It's a beatifully redundant system, that only gets stronger as more products embedd the tags.

    It's great for tracking products, but the civil uses are way, way cooler. Once it's in place it will make tracking by GPS seem silly and arcane, and impractical.

    the thing is that they don't need to tag you, they just need to tag your clothing, the currency you bring in your wallet, your photo id.... etc

    now, all that is required is some sort of global database where they have a picture of you walking through the door, buying a [insert embarassing article here] and form letter blackmail.

    no, i think it's the fact that the issue i bring up is that if your purchases retain the rfid function upon leaving the store, they become useful to the entity that decides to listen and track them: wal-mart's clothing aisle that insists that this pair of pants will match that shirt your wearing...

    it's worse than the safeway club card because you knowingly give the club card to the entity; in this case, it may be against your will.

    The problem is double:

    1. Your credit card info is attached in their DB to all products you have purchased. SO when you enter a store (and you wear RFID tags) they can tell all your buyer history.

    2. People from *outside* your house will be able to tell *EVERYTHING* that is inside. Magic of wireless... Technology freaks will drive around the neighborhoods with RFID readers to detect a 70" TV, or any other expensive stuff interesting to rob.

Then, it prints out a piece of paper with a barcode. You go to the store, and scan the barcode into a little handheld GPS unit. The unit then lights up and shows you graphically where all the products on your list are. If you paid by credit card at home, you walk your cart through the scanner and leave (provided you didn't take anything "extra") and if not, you can pay at the register. Not everything has to be evil....but I will still wear my tin foil hat while shopping at Wal-Mart now.

    Uh..How?

    I'm as big as a privacy buff as the next guy, but how the hell are the amassing a database about you simply by virtue of RFIDs?!

    Like I mention below, the uproar with Benetton's plan was that the RFID was embedded in the CLOTHING. So that when you came BACK to the store, they could, ostensibly, compile a profile of your Benetton purchases by surrepitiously scanning your clothes as you came back in.

    I'm going to assume, unless someone can demonstrate otherwise, that Walmart is interested in putting the RFIDs on the PACKAGING. On the long shot that the RFID *is* in the product itself, who cares? How often are you coming back to Walmart, with, say, the TV or the twizzlers you just bought there? And as for clothes...well, really, if you're dressing yourself at Walmart, you're on you're own, buddy.

    But seriously, Walmart, unlike Benetton, doesn't sell high-ticket item clothes, and probably isn't interested in profiling their typical customers clothes buying habits, really. I doubt Walmart socks will have RFIDs embedded. Probably only the packages will.

I'm not worried about people tracking me, but nothing like putting a transmitter in a car or even a house (what is the range on these things anyway??) that says "I'm an Xbox in here -- come get me!!"

    Two things bugging me about these posts.

    About drive-by scanning: I believe that you need an antenna that's the
    square of the distance to read a tag. That's why there's a little plate reader
    or handheld at the checkout and those walkthrus at the door are huge.
    To read it from 5 feet, you need 25 sq feet of antenna.

    The other thing is that the tag itself won't be zapped or deactivated.
    Each will hold a key that IDs the product (all 10oz cans of peaches from
    DelMonte will have that same key, like a barcode, probably that same UPC
    number) and it will also have a key that's unique to the tag itself.
    It won't be zapped, it will just change the status record of that item from
    "stocked" to "sold" (or "missing from inventory but not sold").
    Shoplift a sweater, and even if you get it out of the store, if you wear it
    to the store a year later, you could get pinged.

    As much as I hate the idea, you can't blame them for implementing it.
    It opens up a huge world of possibilities and won't cost them that much.

    With Wal-Mart's clout, it will be up to the vendor to eat the cost of the tag,
    WM just has to implement the system and specs the tag. No doubt the tag
    supplier will be a WM subsidiary.

    Don't want to put in the tag in your product Mr. Vendor?
    Sorry, we'll find someone else that will.

    Privacy concern: If their not deactivated, your basically wearing a consumer profile where ever you go. Lets say these things catch on everywhere, and become a standard like UPC codes, you walk into Target, or Walmart, or Circle Jerk, door sensor notices that you respond to a ping. Customer #204013 is wearing a Lands End sweater, a pair of JNCOs, a Cubs hat, Fruit of the Loom undies, a Swatch, Nikes, and a Victorias Secret brassier, customer #204013 buys a Jolk and a pack of Camels, and some pr0n. *POOF* A new database entry is born.

    Now imagine that each one of these RFIDs has a unique number, and somewhere along the line you become attached to one of these tags, now all of your purchasing history is associated with YOU, and not an aggregate. And the wonderful thing is, YOU HAVE NO CHOICE. To most people this is no problem, to me, it is. I try my damndest to stay out of all forms of database, with mixed results, and with these tags, I CAN'T. My purchasing history will follow me.

    I don't really see the privacy concern being fixed in reality. RFIDs don't have commercial grade broadcasting capability. Most are designed for their RF signal to be picked up in about a 5-10 foot radius. If the broadcast range was too long, they would burn out too quickly to be efficient for stocking shelves. Additionally, long range RFIDs would be so cost-ineffectual that nobody would integrate them into their products. So if you got your stuff home and the RFIDs weren't deactivated, Walmart would have to come in your house and start scanning your shelves to find out what you have.

    The REAL consumer issue I see here is the additional cost of RFID tagging. Barcodes cost little (when you consider the registration costs of a barcode/SKU) and the ink it costs to print spread across millions of units produced. In effect its less than a penny of your purchase. But these, even at positive estimates, will be about 5 cents a piece once they are implemented in mass quantities. This price will inevitably be passed to consumers, but probably phased in over time and hid as an inflation cost. The problem is most time cost increased are passed on in this mannor, the price is jacked up a little bit more because the stores can get away with it. A 5 cent increase of time eventually becomes a 6 cent increase. That may sound little, but think about every unique itme you buy. If you buy 100 items a month (typical grocery buying habbits), you contributed 1 more dollar. Multiply that by customers coming through a store and you see tens of thousands of dollars of additional revenue artifically created because of RFID implementation. This profit increases the larger the store is and the more individual products sold. This is why you see stores like Walmart, Target, Best Buy, etc. buying into this plan.

    The main reason they check your reciept is not because they think that you may be a thief. It is because they think that their cashiers may be thieves. A standard ploy is for the cashier not to ring up expensive items for a partner. Anyone who has shopped at Fry's Electronics has noticed the "body cavity search" and the reason is that cashier A, by not ringing up a few RAM chips for their buddy customer B, could share in a pretty impressive haul. So the search is desinged to prevent this. The net effect is that Frys/Walmart/Home Depot can then afford to hire non-perfectly honest cashiers, which are much cheaper than honest cashiers, and they pass the savings on to you!

    So don't be offended by the search- or shop elsewhere! People who are outraged by privacy/security issues are ok, but when people feel entitled to privacy AND deep discounts, that seems too much to me.

    I too have been in this situation - doorpost alarm goes off, security come a-running, and they've tried to hold and search me.

    The interesting part? What set off the alarm was my keyring! After a little experimentation at the local corner store/video rental owned by a friend, I learned that if my 2 car keys are angled together in *just* the right way, it sets off the doorpost anti-theft alarm. These things work by detecting a resonant circuit, and I guess the angle + cuttings of the keys matches the frequency of these things.

    Seriously, I want every scrap of wood and piece of paper in my house to have RFID's. RFID represents a merging of our informational universe with the physical. With RFID tags on items, I can represent them in my PDA and have them be hi-lighted in a HUD mounted on my glasses.

    Imagine never losing anything again ever. That's a serious possibility of a world in which RFID tags are ubiqutous.

    Yes there are potential privacy issues, but there are always privacy issues with any convenience technology. We get around them on a case by case basis as usual (e.g snail-mail: porno subscriptions arrive in brown paper wrapping).

    How is the RFID worry any worse than TCP-IP, which passes through many unsecure places on the way to its destination? It's not, we've just already got a good handle on TCP-IP security, but noone's thought of similar ways to handle RFID.

    They will, and the problems will be solved, as they always are. The sky isn't falling, it never does.

    Assuming that these RFIDs can be turned off. I suspect it's more likely that the RFID is marked as "sold" in their records. If RFID makers can get together and come up with a numbering scheme that would avoid duplicates (similar to MAC addresses) then it shouldn't be a problem.

    The bigger problem is that Walmart tries something like this:

    Joe Blow buys a pair of shoes.

    He pays for them with something other than cash that has his name and address.

    Walmart now sells access to their records to other stores.

    Stores with RFID readers embedded in the floor of the entrance can tell who you are when you walk in. Now they know who you are, your shopping habits, etc.

    The above example could be a good thing if we could only trust companies to protect our privacy (which, IMO, we can't) by allowing companies to give us personalized shopping.

    When Walmart does something everyone notices and reacts. Many have learned that you can't compete with them but you can make money by servicing areas that they have decided not to persue. I suspect that most companies will quitly embrace Wally Worlds actions concerning this.

    Does anyone know what frequency or frequency range these passive RFID's work in? It should be possible to build a 1 milliwatt transmitter on that frequency for one's own house, thus ensuring that products at home remain well behaved (anonymous).

    Secondly if something I purchase is going to be sending an ID to readers that I don't specifically authorize, I'd like to get my own reader so I know with certainty that I've located and disabled the RFID on or in the product, since my own reader stops picking up a response/reply from the RFID.

    Ok. Here's my $0.02 worth. I have no issue whatsoever with these things being used in the store where the merchandise is purchased. In that respect, they're no different from electronic anti-theft tags.

    I have a BIG problem with leaving the tags active and able to respond outside of said store environment. So, with that in mind (and maybe this should be turned into an 'Ask Slashdot' question):

    What countermeasures are available to kill the tags, but not harm the item they're attached to, once you leave the store environment? Some ideas that come immediately to my mind are:

    (1) Stuff your purchase into a microwave oven for a few seconds. That should effectively fry the tag. Unfortunately, this may not be practical for clothing containing metal buttons, zippers, or snaps.

    (2) Build or buy a small EMP device designed expressly to destroy the tag's functionality. Could have varying degrees of difficulty, depending on one's skill with electronics, or the availability of such devices at the commercial level.

    (3) Other ideas...?

    And why should they employ people to do a job they can get out of a machine more cost-effectively? Maybe we should stop using machines in car factories and restore lost manufacturing jobs?

    Do you know why you have a grocery store just up the road from you that's stocked with plenty of good food of different varieties at all times of year? Do you know why the average working adult in your town can afford an automobile? Do you know why you have a computer with which to post on /.?

    It's because we have an economy that's not afraid to put people out of work to improve efficiency. People can find new jobs. They might have to move or learn new skills, but that's life in the industrialized world. If you don't like it, there are some pre-industrialized countries you can go to where you'll earn a steady, miniscule pay for the same job all your life.

    Take the example of the United States. Since the end of the depression, unemployment and inflation have remained relatively stable and low. But the standard of living has increased tremendously for the average white male. (It's increased even more dramatically for other people, but that's also partly because they learned to fight for their civil rights.) Yes, the short-term unemployment people experience can be very painful. That's why we have (or should have) unemployment benefits and other forms of a social welfare system to help the unemployed find new jobs.

    So don't complain about automated checkout counters putting people out of work. When they do find their next jobs, they'll be able to spend less of their income on food.

There are two ways to write error-free programs; only the third one works.
