The World’s Thinnest Active RFID Tag?

Written by Fred J. Aun

A Pennsylvania-based RFID tag-maker is introducing what it says is the thinnest active RFID tag in the world. CenTrak CEO Ari Naim said the size of his company’s new 3mm-thick IT-740 Staff Badge makes it an ideal tool for keeping physical track of not only employees but also of expensive equipment that can be moved, such as notebook computers. “It is pretty thin, at 3mm, for an RTLS tag,” said ABI Research RFID analyst Michael Liard. “The advantage is that the tag does not need to be the badge itself. You can overlay the active tag on current badges — retrofitting them if you will.”

Asked about the new tag’s battery power, Naim would only say that battery life is one of his company’s “specialties” and that power specifications aren’t very informative. “That, honestly, doesn’t give you much information,” said the CEO. “What defines the life of the tag has to do with how the system works. Our system updates every three seconds. If we change it to update every six seconds the battery life would nearly double.” Naim said the IT-740 unit can be programmed to operate at varying intervals and has a motion-sensor that can be used to prevent activation if the unit remains stationary for certain periods of time, such as when it is not tracking product.

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...
