Large Metro Group RFID Trial Claims Strong Read Accuracy

Written by Evan Schuman

The world of retail technology has learned to always take notice when the Metro Group–a massive German retailer–starts to take anything seriously. So when Metro this week confirmed that it had invited Checkpoint Systems to join its ambituous 36-dock door trial of Gen2 RFID, it raised some eyebrows. Checkpoint’s official role is hardware integrator for the trial.

Each of 36 adjacent dock doors at the Metro distribution center was equipped with a Gen2 RFID reader, according to a story in RFID Update. At the same time, pallet loaded with about 60 tagged Procter & Gamble goods was passed through each portal and onto a docked truck at full operational speed, meaning each pallet was in the RFID read field for between one and one and a half seconds, the story said. A joint statement put the accuracy at a “98.6-percent-plus read rate simultaneously from multiple pallets as they were wheeled through the dock doors.”

“The results represent a significant milestone in European RFID operational deployment,” said Dr. Gerd Wolfram, Managing Director of Metro’s Information Technology Group.

    It would be very instructive if Metro published a more detailed description on the methodology used to conduct these trials. The implication is that the raw read rate of both pallet tags and case tags reached the very promising level of 98.6%. However, this conclusion is contrary to the results recently published by Cardinal Health where their read rates were very low, and they recommended the use of “inference” reads, derived from an Advanced Shipping Notice (ASN), to improve the read rate to acceptable levels.

    If Metro is relying on the ASN to bring the accuracy to 98.6%, then that raises the question as to why the read rate was not 100%. Were there instances where readings from a pallet load were actually 0?

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...
