Credit Cards with RFID Chips

Boston Globe covers the controversy around RFID-equipped credit cards. Apparently, 20 million Americans already have one of those, and Nokia is planning to embed RFID chips into their cell phones that could eventually replace plastic altogether. I wonder what people lose more often: credit cards or cell phones? Besides, when you lose your plastic card (I just did last weekend), you can use the cell phone to call and cancel it, but what happens if you lose your phone with your credit info on it?
