German Grocers Tagging Workers To Limit Time In Freezers

Written by Evan Schuman

While U.S. retailers—including Macy’s and JCPenney—are just starting to get comfortable with item-level RFID, a pair of German supermarket chains is already taking the next step—tagging associates, too. By using active tags, the chains are able to not only handle access to sensitive areas but flag when an employee has been in a freezer too long and may need help.

The grocers, ALDI and Lidl, wanted to offer hands-free access to security areas, said this report from RFID Journal. “Lidl installed a reader inside the freezer near its entrance. When a person with a transponder arrives, the ID number is recognized, unlocks the door and allows him entrance,” the story said. “As he remains in the freezer, the reader continues to read the tag once each second. If it is still reading the tag in 15 minutes, it triggers a loud siren that can be heard outside the freezer.” It’s long been argued that RFID can deliver retail ROI, but only if retailers forget what vendors have promised and start getting creative about discovering their own ways to profitably use the tags to do what can’t easily be done any other way. Looks like ALDI and Lidl have already started thinking outside the box—and inside the freezer.

Why Did Gonzales Hackers Like European Cards So Much Better?

I am still unclear about the core point here-- why higher value of European cards. Supply and demand, yes, makes sense. But the fact that the cards were chip and pin (EMV) should make them less valuable because that demonstrably reduces the ability to use them fraudulently. Did the author mean that the chip and pin cards could be used in a country where EMV is not implemented--the US--and this mis-match make it easier to us them since the issuing banks may not have as robust anti-fraud controls as non-EMV banks because they assumed EMV would do the fraud prevention for them Read more...
Two possible reasons that I can think of and have seen in the past - 1) Cards issued by European banks when used online cross border don't usually support AVS checks. So, when a European card is used with a billing address that's in the US, an ecom merchant wouldn't necessarily know that the shipping zip code doesn't match the billing code. 2) Also, in offline chip countries the card determines whether or not a transaction is approved, not the issuer. In my experience, European issuers haven't developed the same checks on authorization requests as US issuers. So, these cards might be more valuable because they are more likely to get approved.

A smart card slot in terminals doesn't mean there is a reader or that the reader is activated. Then, activated reader or not, the U.S. processors don't have apps certified or ready to load into those terminals to accept and process smart card transactions just yet. Don't get your card(t) before the terminal (horse). Read more...
The marketplace does speak. More fraud capacity translates to higher value for the stolen data. Because nearly 100% of all US transactions are authorized online in real time, we have less fraud regardless of whether the card is Magstripe only or chip and PIn. Hence, $10 prices for US cards vs $25 for the European counterparts. Read more...
@David True. The European cards have both an EMV chip AND a mag stripe. Europeans may generally use the chip for their transactions, but the insecure stripe remains vulnerable to skimming, whether it be from a false front on an ATM or a dishonest waiter with a handheld skimmer. If their stripe is skimmed, the track data can still be cloned and used fraudulently in the United States. If European banks only detect fraud from 9-5 GMT, that might explain why American criminals prefer them over American bank issued cards, who have fraud detection in place 24x7. Read more...
