Metro Finds RFID Accuracy Not A Problem

Written by Evan Schuman

With the $81 Billion Euro retail giant Metro Group having formally gone into full-fledged RFID deployment, a senior executive there says the efficiencies the chain saw in trials was too compelling to not deploy.

The chain has informed all of its suppliers that they need to ship all RFID pallets to Metro fully RFID tagged by October 1, 2007, said Gerd Wolfram, an IT managing director for the chain.

The initial phase of the full rollout will impact about 180 locations, Wolfram said, including about 60 Cash & Carry stores, nine distribution centers, some wholesale locations and 100 Real stores.

One of the key hurdles to full-scale RFID deployments with U.S. retailers has been low read accuracy rates, but Wolfram said that wasn’t what his people found in European testing. “It’s not a problem at all on the pallet level,” he said, adding that pallet-level read rates were “about 100 percent.”

It’s only slightly weaker on the case level, Wolfram said, describing that read-rate accuracy “at around 95 percent to 100 percent.”

But Wolfram argues that even at the lower accuracy rate, the efficiency they found from RFID would have easily made up the difference. “Our business people, they benefit even from 95 percent,” he said, “compared to the process we have today, with people running around the pallet and counting every case on the pallet” manually.

It’s much more efficient for a few reasons, he said. First, errors creep into even accurate manual reads of typing errors. Secondly, the manual checks were random spot checks compared with the automated RFID checks that theoretically count every case in every shipment.

“Then (factor in) the time we need to do it manually and that this is better data quality,” Wolfram said. “We now know exactly what is in the stores” and those products are easier to find.

The Metro move is likely to be a key domino in global retail RFID support, with Wolfram predicting that his U.K. neighbor will be next. “Tesco will follow with an even bigger rollout,” he said. “There is now movement in the market and it will go forward.”

In the U.S., Wolfram says Wal-Mart will be joined by more aggressive efforts from BestBuy and Target. “In Japan, they do a lot of things with item-level, but they don’t talk a lot about it in public.”

But mere support of RFID will not deliver most of its benefits and this technologically change needs to be accompanied by a business process change, he said.

“This is basic innovation in retail. This is the next step forward. But the real innovation is that we must change the process,” Wolfram said, adding that many of the dire predictions for RFID have been based on a lack of comprehension. “People have minor understanding what RFID really means in a retail environment,” Wolfram said. “Even the IT management does not have the knowledge, they don’t see the potential. Therefore, they answer very pessimistically about RFID.”

Also to be blamed are trials that are run by technologists only. “Sometimes IT is doing the trial only. If you don’t have the business people on the trial, it’s useless,” he said.

What about unenthusiastic suppliers, that seem to be doing the bare minimum to be RFID compliant? “We also have these kinds of suppliers. We have to educate them and we have to push them harder,” Wolfram said, adding that they are going to be strict requirements for things such as advanced ship notices. “We will punish those in the future” who do not cooperate.

Metro will be using Intermec RFID starter packs along with Reva Systems’ Tag Acquisition Processor products.

  1. Chris Kapsambelis Says:

    Mr. Wolfram compares RFID read accuracy to manual counting and keyboard entry. However, the current state of the art is the use of Barcode and EDI (Electronic Data Interchange).

    If Metro is not using EDI, then their zeal for RFID is completely understandable. In the U.S. EDI is very common. RFID had the potential to eliminate Barcode and EDI with the promise of reading the EPC of every case in a pallet load. This level of automation would not only eliminate to need for manually reading and counting cases but would also eliminate the need for Barcode, EDI, and ASN (Advance Shipping Notice). To realize the efficiencies of full automation, in the supply chain, the read rate needs to be 100%. The poor read rate of RFID makes this impossible, and RFID is now proposed as a supplement to Barcode and EDI requiring ASNs to fill the data gaps produced by RFID.

    In this role, the extra cost of RFID cannot be justified.

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...
