The Digital Way To Kill EAS Tags And Keep ‘Em Dead

Written by Evan Schuman
November 15th, 2012

EAS tags have an annoying tendency to come back to life after being deactivated. That’s embarrassing for the shopper who sets off the alarm, but it’s far more embarrassing for the LP executive whose people grow tired of the false alarms and start ignoring them—especially at peak times. One EAS vendor on Tuesday (Nov. 13) tried to end the LP Frankenstein monsters by switching to a digital—rather than a mechanical—tag mechanism, one that can be fully fried by the typical 10-volt deactivation pad jolt.

“We make this happen at the nano level, leveraging very very small geometries,” said Amir Mashkoori, CEO of EAS vendor Kovio.

The tags are soft tags and Kovio’s approach is to try and get manufacturers to embed them deep within shoes and other clothing so they are not visible to the shopper, which makes the removal of the devices almost impossible without severely damaging the product. Mashkoori argues that this could change many standard retail tactics, such as having only one shoe on the floor and forcing the associate to go to the backroom to get the mate.

The way existing EAS tags—both hard and soft—reactivate is by the position of tiny elements. When the elements are apart, the alarm rings. The deactivation system brings them together. But through washing and walking (in the case of shoes), the elements can slowly reposition to the point where they are again apart and, therefore, active.

By switching to a digital system, Mashkoori said, there’s no way for the tag to be reactivated once it is properly fried. And that proper frying comes courtesy of the same pads that, today, deactivate mechanical EAS tags. This was done to try and minimize the cost and to preserve investments.

The problem with this approach, which certainly is a key step in the right direction, is that it is designed for the current cashwrap stationary POS model. In a mobile in-aisle checkout model—or a self-checkout apparel approach, such as the one Walmart has experimented with—that 10-volt deactivation pad becomes downright unwieldy.

Mashkoori pointed to portable deactivators, but there are two inefficiencies with that. First, either they have to be carried or lots of them have to be scattered throughout the store. As for lots of them being scattered throughout the store, these are units whose sole purpose is to deactivate anti-shoplifting devices. Yeah, you want them under strict control.

That means the pads have to be carried. In the short term, that’s fine. But the beauty of mobile transactions being able to happen anywhere in the store won’t be helped by this bit of lugging.

The second inefficiency is workflow interruption. After scanning, deactivation is a separate effort. And if an associate forgets, you get even more false alarms.

Given that the soft tags are digital, why not consider a system where the POS—upon purchase completion—can wirelessly deactivate the soft tags and do so automatically?

No, we’re not talking about a mobile-issued 10-volt zap. Other than it requiring more power than many phones can safely handle, Mashkoori goes back to the anti-theft concept. “You don’t want this capability in a mobile phone, (with customers) going around deactivating everything,” he said.

But simply including a self-destruct element in the tag that can be triggered by a secure signal from the POS, one that would presumably be difficult for a shoplifter to replicate, is a good option.

It’s a few years away, though. For now, anything that cuts down on EAS false alarms is worth considering.

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...
