RFID blocking card holder.

[randomness]

I've been carrying around one of these for a few years now, and it's pretty banged up.

Last time I rode Metro I decided I'd see if my SmarTrip card could be read through the aluminum case. It couldn't.

I'd like to do more testing with an RFID reader and the rest of my cards before I declare that the case is useful for shielding the various cards they're busily stuffing RFID chips into, but at least I've got some evidence that it may work.

I don't know what my cigarette case/wallet is made out of, but it's metal; I wonder if it would work as well.

It's certainly worth testing.

In fact, you could test it with one of these.

Yes. I keep meaning to get one. Thanks for the link. :)

Hmm.

I know the former director of the AutoID lab at MIT who is now in private business doing this kind of thing. Wonder what I could find out from him.

Kind of changes your opinion of people walking around wearing pointy tin foil hats, doesn't it? ;)

How's bedfull_o_books? We miss her at rehearsals.

Hi! bedfull_o_books said she saw you at the concert!

(I'm sorry I've been out of touch; work's got me running back and forth to Connecticut recently, so I haven't been free much when I've been in town.)

I've been using one of these Bungee Card Case's for about 5 years now. My work/play RFID cards won't scan unless I take them out of the box, which makes me happy.
