How Retailers Watch You

garzpacho writes, "With $30 billion lost to shoplifting and employee theft last year, retailers are turning to increasingly sophisticated electronic surveillance systems to fight theft. Some systems, like RFID tags, have been well-publicized by privacy advocates. Others are less well known: video surveillance systems are being tied to software that can recognize specific types of activity and identify individuals; and data-mining software is being used to analyze everything from shoppers' habits to irregular register activity." From the article: "Despite this revolution in retail tech, you won't find many stores bragging about their new security tools. No one wants to tip off shoplifters or advertise that they suspect their customers. That's why so much of the technology is hidden in the first place. But another reason stores don't talk much about surveillance is that they know it sparks concerns about privacy. Consumer groups and legislators have opposed the spread of RFID and video surveillance for just that reason."

  1. Proper enforcement is still key by Kelson · · Score: 5, Insightful

    I can think of a number of times when I've bought something and the clerk -- whether new to the job, distracted, or just lazy -- has forgotten to deactivate or remove the RFID tag, and I've walked toward the front door and had the alarm go off.

    The most recent was just two days ago -- I'd ordered a DVD on sale from Best Buy's website, and chose the store pickup option. Basically you choose a nearby store, they hold it for you at the customer service counter, and you walk in with your order info and pick up the item and a receipt. The customer service people presumably hadn't been trained to deactivate it, and I certainly didn't have any reason to go through the line -- I'd paid for it already, after all -- and the greeter/receipt checker certainly had no reason to think that it hadn't already been deactivated. It wasn't a big deal, as the guy had already seen my receipt and just took it over to the counter to deactivate it, but it was still an easily-avoidable false alarm.

    The worst are clothing and/or department stores, especially around holidays. A couple of years ago I bought an item at Robinson's May on the second floor, walked downstairs, walked out the door, had the alarms go off -- and no one reacted. OK, I had a store bag, but if I'd been a shoplifter, I could have walked right off and no one would have noticed, despite the blaring alarm. I went back and forth a few times to make sure it was my bag, then went to the nearest cash register -- note, not anywhere near where I paid for it -- told them what had happened, and they didn't even check my receipt before pulling it out and removing the tag.

    I've been at other clothing stores and heard the shoplifter alarm go off repeatedly during a half-hour stay. I think I've only seen an employee approach someone once. I assume this means there are so many false alarms that they have no sense of urgency when an alarm goes off, because most of the time, it's a customer who is going to come back of their own volition so they can get the tag removed and actually wear whatever it is. It's just sound and fury.

    You can have the greatest detection tech in the world, but if people don't use it properly, it won't help one bit.

      Some stores are just more with it than others. Like J Crew, Gap also uses the sewn-in EAS tags, but they seem to be pretty bad about deactivating them (and about telling customers to cut them out). I found this out the hard way when I didn't notice one in my 3-year-old's jeans and she set of theft alarms wherever we went.

      When I worked in Accessories at Dillard's in Austin, I was right near an exit to the parking lot. Our alarms went off all the time, but it was seldom because of our own merchandise. Most often, it was because of stuff from the Gap (I can't help wondering if the Gap even bothers to turn on their security system, because it seems like active tags make it out of their stores pretty regularly). We did not remove other stores' tags: customers were always sent back to the store where they purchased the items to have the tags removed.

      Interestingly enough, a store's own employees usually account for the majority of shrinkage. I didn't realize quite how closely they monitored us until one day security called me at the jewelry counter and asked whether I had just seen my co-worker at the watch counter take a very expensive watch out of the display case and add/remove links. They wanted to know if I had any idea what she was up to, and even asked me to keep an eye on her for the rest of the shift!

      I'm sure they also monitored our actual cash register transactions pretty closely. The whole register system had an OS/2 database backend. It was pretty cool actually - you could pull up all kinds of statistics about the sales pretty much in realtime. I know they kept track of things like whether credit cards were scanned on the electronic signature pad or if the customer signed on hard copy (in which case, the store paid a penalty fee to the signature pad company), so I'm sure they also audited other employee actions as well.

      Here are some of the strategies our store used:

      • Proof of Purchase (POP) labels - every item got a bar code sticker put on it and scanned when it was purchased. It's pretty easy to tell at a glance whether an item has the sticker or not (returned items make this a little tricky though).
      • Employee discount tied to a store credit card - the employee discount did not get applied at the time of sale, but rather was deducted as a credit from the credit card statement. This seriously cut down on fraudulent use of the employee discount.
      • Employee purchases held at the Customer Service desk until end of shift - if you bought something on your break, you took it to Customer Service where they inspected the receipt and sealed the bag. You only got the bag back once you clocked out. I kind of remember security checking the bag again when you left the store.
      • No employee bags on the floor - employees had to use see-through bags for their belongings and leave them in their lockers. A small bag (i.e. makeup-bag-sized) for personal items was allowed in the retail areas of the store.

      Security personnel are not police officers but are often confused with them due to similar uniforms and behaviors, especially on private property. Security personnel derive their powers not from the state, as public police officers do, but from a contractual arrangement that give them 'Agent of the Owner' powers. This includes a nearly unlimited power to question with the freedom of an absence of probable cause requirements that frequently dog public law enforcement officers. Additionally, as legal precedents have further restrained the traditional police officers' power of "officer discretion" regarding arrests in the field, requiring a police officer to arrest minor lawbreakers, private security personnel still enjoy such powers of discretion largely due to their private citizen status. Since the laws regarding the limitations of powers generally have to do with public law enforcement, private security is relatively free to utilize non-traditional means to protect and serve their clients' interests. This does not come without checks, however, as private security personnel do not enjoy the benefit of civil protection, as public law enforcement officers do, and can be sued directly for false arrests and illegal actions if they commit such acts. ...

      Except in these special cases, a security guard who misrepresents himself as a police officer is committing a crime. However, security personnel by their very nature often work in cooperation with police officials. Police are called in when a situation warrants a higher degree of authority to act upon reported observations of the security personnel that could not be directly acted upon safely by the security personnel.

      Suppose you buy a shirt at Walmart and take it home and wear it, and at some point go back to Walmart wearing that shirt. How can you prove you paid for it previously? Suppose it's a handbag or wallet. Prove you didn't just steal it from the store.

      Why bother trying to prove this? You don't need to prove anything. Let them worry about proving your guilt. And if somebody sells clothing that contains chips that set off alarms, then setting off alarms isn't proof of theft -- hell, it isn't even circumstancial evidence of theft anymore. It's just noise and makes theft detection harder. This isn't your problem (unless you own Wal-Mart stock) so let someone else have this headache. Don't worry; be happy. :-)

    I was doing some low voltage wiring repair at a high end lighting retailer. Turns out that their shrink was staggering before they simly installed some video cameras in the wharehouse. Some of them were not even functional, but you could not tell which. Their employee theft problem went away over night.
    The threat.. implied or real.. of watching employees is often enough to encourage desired behavior. It is a direct application of game theory.

    For supermarket chains, the serious losses are not from shoplifting. The really serious theft is the entire truckloads of goods that never make it in the backdoor of the store, but that the chain ends-up paying for. These operations are usually operated by insiders, often reaching up to quite senior management levels, as full-time businesses-within-the-business.

    None of this tracking nonsense is going to make the slightest dent in that.
