As I was looking at the wallets phishphreek linked to the post I thought about the possibilities of them making bags and such and was wondering about an increase in theft possible.

Well, in the same way you block signals from your radiating items. Couldn't you block signals from store merchandise. (Yikes!) What does the future hold for shopping? Doesn't this possibly negate the effectiveness of those detectors at the front of almost every store you go into now?

Its funny with the on coming of new technology into the main stream of society many other things become obsolete. This should be something storeowners should keep an eye on. Don't throw out the surveillance cameras just yet.
