Wal-Mart Gives Suppliers RFID Holiday Gift

Spreading holiday joy among its suppliers, the nation’s largest retailer has softened its RFID compliance deadline.

In a briefing with analysts, Wal-Mart CIO Linda Dillman said that its top 100 suppliers?plus 37 “volunteer” suppliers?will start shipping cases and pallets by February to three Wal-Mart distribution centers. The original deadline was Jan. 1.

Wal-Mart officials have softened the rollout to phase in through “early February,” said Christine Spivey Overby, an RFID analyst with Forrester Research. According to Overby, one Wal-Mart executive said that some suppliers waited too long to place orders for tags, which means the tags won’t ship until late January or even early February.

“I think there will be no big bang [on Jan. 1], and I don’t think they ever expected a big bang,” Overby said in an interview. “What’s going to be happening in January is a pilot on steroids.”

Based on preliminary testing, Wal-Mart also is seeing a better-than-hoped-for percentage of products being tagged. “Wal-Mart calculates that, while tagging plans vary from less than one percent to 100 percent, suppliers will tag an average of 65 percent of these supply chain units,” Overby said.

Another analyst?Kara Romanow, a research director at AMR Research?heard the same figures, but suspects some statistical sleight of hand.

“At the risk of not complying with Wal-Mart’s mandate, almost every single supplier will be technically compliant, each tagging a handful of products,” Romanow said, adding that most will tag between two and 10 products. “In some cases, those SKUs actually represent the same product with different colors or flavors. Wal-Mart reported to us that the average SKU count being tagged is 65 percent, but we believe that is heavily skewed toward smaller suppliers and volunteers that only have a handful of products and are therefore tagging a higher percentage of their products.”

The Wal-Mart testing hasn’t been limited to its key distribution centers, according to the analyst briefing. Since April, Wal-Mart and eight of its top 100 suppliers have been testing tag and reader performance across both distribution centers and Wal-Mart stores for about two dozen products, a Forrester report said.

The good news is that accuracy has sharply improved. But is it good enough? “Yes, Wal-Mart is reporting that the accuracy has improved. Does it mean that they’re where they want to be? Not by any means,” Overby said.

“While initial read rates were between 40 percent and 60 percent, the Wal-Mart team indicated that it’s now seeing rates in the high 90s at key read points like the manual conveyor and box crusher,” Overby said. “One exception the team noted: It’s currently only reading between 50 percent and 90 percent of cases moving from the back room to the front of the store on a pallet. Still, Dillman and the team see this as significant progress, as Wal-Mart couldn’t track this movement previously.”

An unexpected benefit of RFID, according to the Wal-Mart briefing, is the ability to remotely watch pallets to keep store traffic flowing optimally. “Wal-Mart can now ‘see’ if pallets and stocking carts are off the floor by 7 a.m., which reduces clutter in the aisles during prime shopping hours,” Overby said. “When it comes to RFID’s impact on product availability, the team admitted that it and the suppliers are learning how to measure the correlation.” She said a Wal-Mart executive pointed to product availability as “one number that we [still] can’t measure. We won’t know the impact until we start fixing and measuring.”

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...
