I've written before about the non-existence of RFID credit-based card offense, a least as marketed by all the sellers selling anti-RFID shielding products. I'm one of the few voices constantly stating that buying RFID-blocking wallets and handbags, sleeves and the like would be a waste material of time and money. I've frequently said that I can't find a single documented case of RFID credit card offense. Each time I write about this, I get tons of angry email from vendors of such products as well as people who "just know" that they have been patients of RFID cards crime.The "victims" who write me personally always speak about a secret man, acting strangely, who walked by with an obvious device, that they firmly believed to be an RFID reader, and soon enough thereafter their credit cards has a fraudulent fee on it. I usually answer that a "feeling" that RFID fraud happened just isn't evidence of an genuine crime, and this I still, after FID car offense has most likely took place.
