We live in a world where cashless transactions are the rule, but there’s a price to pay for such a convenience. Credit and debit cards with embedded microchips are common because computers can read them quickly, and the chips don’t transmit a large amount of personal data, unlike the magnetic strips on cards. That protects you against identity theft and fraud, but the bad guys have adapted.Some thieves use handheld readers to get the numbers and expiration dates of cards embedded with RFID (Radio Frequency Identification) chips. Not all cards have these chips, but enough do to motivate thieves to get handheld readers and steal credit card numbers. Additionally, U.S. passports issued after August 2007 have embedded RFID chips, which allows for faster movement through borders and customs, but again opens the door to electronic pickpockets.That’s why RFID blocking wallets, which are built with layers of material that RFID readers can’t penetrate, are being used by more and more people. Here are a few types you should consider.
