I saw this post from Bonnie over at Quiltville. http://quiltville.blogspot.com/2011/07/whats-in-your-wallet.html
I think it bears repeating.
I met someone just a week ago that had this happen to him and three other friends. He thinks their credit/bank cards were scanned (from their pockets!) when they were eating together at a restaurant. All four of them had to deal with the aftermath of straightening up the issues that occurred from the identity theft. This is the first time I actually knew of someone that it had happened to. It makes it all very real.
