A friend of mine this morning asked me if they encode personal information, such as name and credit card data onto hotel key cards. He had received a message suggesting that this happens, and the message recommended keeping the card when you check out of your hotel, to prevent thieves from getting the information. This is one of many urban legends that have cropped up over the many years, and preys on the fear of technology that pervades the older generation. To debunk this myth, I sent my friend to Snopes.Com, the Internet's best source on Urban Legends. Perhaps you're familiar with the movie, or the 'Bloody Mary' legend?
