RFID Blocker Demonstrated

from the good-to-see... dept

Tue, Feb 24th 2004 10:27am — Mike Masnick

There has been a lot of talk lately about RFID chips - both good and bad. They have tremendous potential, but also have some privacy questions associated with them. However, as we pointed out last summer, some researchers at RSA have been working on creative solutions to the privacy problem by creating an RFID blocker tag. It was kind of surprising that this news didn't get more coverage and seemed to go away quickly. Very few of the discussions about RFID privacy issues mention the potential of a blocker tag. However, now, RSA has begun demonstrating how the blocker tag works and maybe it will get some more attention. Unfortunately, it's not as impressive as I had hoped it would be. The demonstration involves a shopping bag that has a blocker tag. Anything in the bag is thus unreadable by RFID readers. The problem with this is that it still requires you to take the item out of the bag to scan. I was hoping there would be a more dynamic way of doing this so that items could be scanned from within the bag, but only when necessary and from the specific reader with permission to read it. Hopefully, that's where the technology is headed.

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.

While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

RFID Blocker
I just want to say that I own the patent to this and/or am already selling this on eBay.

I'm surprised that it didn't get coverage for the potential misuse by criminals. I walk into department store X that uses RFID for security with an RFID blocking bag. I walk out the side door with as much stuff as will fit into the bag.

The technology reminds me of radar detectors. Everyone knows how useful it will be, but for whatever reason, mainstream use is not very high. I don't really need them to RFID block my purchase of Cocoa Puffs. Take all the info you want from me, just don't let those crazy radio waves cause cancer or anything...

Re: RFID Blocker
BULL! And big deal! do you think the people in China care if you own a pantent? In France, NO ONE CARES. The product will still sell with or with out the patent.

blockers/zappers
it sucks that consumers just cant pass a law forbidding item level tagging in the first place. There are NO reasons to track AFTER purchase, THINK about it! I believe an ITEM LEVEL DETECTOR is tha invention to pursue and DONT BUY TAGGED ITEMS AS THEY CAN BE RE ACTIVATED! A receipt for returns with no id required should be sufficient. I would even give up my "right of return" if push came to shove to protect my privacy!
