Foiling Card Readers
Radio Frequency Identification Devices (RFID) are embedded in numerous products and over the past several years have made their way to financial items such as credit and debit cards. There are an estimated 140 million Americans with RFID embedded credit or debit cards. Through using a cheap RFID reader that can be purchased online or through numerous stores, someone can steal credit card numbers and expiration dates. To help prevent such identity theft, patrons should carry multiple cards with RFIDs in their wallet/purse so that it will confuse a reader or the wallet can be shielded by inserting some aluminum foil into the wallet.
