Pickpockets are getting smarter. With RFID (radio frequency identification) scanning technology they only need to get within a few feet of you. RFID scanners the size of a remote control near your credit cards and voila! They now have your credit card numbers, expiration dates, and other information from any card that is RFID enabled. The new credit cards with chips contain RFID signals to enable quick pay for your convenience. RFID signals cannot penetrate aluminum. Buying a RFID blocking wallet or card wallet is like buying insurance. A small purchase now can save you a lot of money, time, and hassle dealing with fraud-related charges later.
