This seems as good a place as any for this. With the Wal-Mart anouncement today of putting tags in clothes, I was wondering if there was a reliable way to detect and if you chose to, destroy these things?
I've seen some rather odd ideas other places which seem a bit extreme to take care of the problem. I may buy a shielded wallet after reading some of these articles but other than that, what can we do? Thanks in advance for your advise!
