Protect your digital identity from high-tech thieves with the Pacsafe RFID Credit Card Sleeve Twin Pack. Modern credit and debit cards come embedded with "smart chips" that emit radio signals, making them vulnerable to illegal skimming by thieves using handheld readers in crowded airports or stations. These slim, lightweight sleeves act as a Faraday cage for your wallet, creating a protective shield that blocks these signals and prevents unauthorized scans of your card number, name, and expiry date. Designed to be ultra-thin, they slide easily into your existing wallet card slots without adding bulk, offering a simple yet essential layer of defense for your financial data.
