# What is RFID Technology in Wallet RFID technology in wallet refers to the integration of Radio Frequency Identification (RFID) blocking features into wallets, purses, and cardholders. This technology is designed to protect your contactless credit cards, debit cards, passports, and ID cards from unauthorized scanning or digital theft, a practice known as "skimming" or "RFID hacking." As our daily lives become increasingly digital, the security of our personal and financial data has never been more critical. I personally experienced a moment of panic when I realized how easily someone could potentially access my card information without physical contact, which led me to dive deeper into understanding and utilizing RFID-protected wallets. ## How RFID Blocking Technology Works in Wallets RFID blocking wallets incorporate materials that create a Faraday cage around your cards. This cage blocks electromagnetic fields, preventing RFID readers from communicating with the chips in your cards. Essentially, it's a shield that keeps your data safe. ### Technical Specifications of RFID Blocking Materials * **Material Composition:** Typically made from a layer of metal alloy (like aluminum or copper) or a metallic mesh fabric (often carbon fiber or nickel/copper polyester). * **Shielding Effectiveness:** Measured in decibels (dB). Effective RFID blockers provide attenuation of 40 dB to 85 dB across common RFID frequencies. * **Frequency Range Blocked:** Covers the standard RFID/NFC frequencies: * Low Frequency (LF): 125 kHz - 134 kHz (Used for animal tags, some access cards) * High Frequency (HF): 13.56 MHz (Used for most contactless credit cards, passports, NFC) * Ultra-High Frequency (UHF): 860 MHz - 960 MHz (Used for inventory tracking) * **Physical Integration:** The blocking material is seamlessly laminated between the inner and outer layers of the wallet's leather, fabric, or synthetic material. **Note on Technical Parameters:** The above technical parameters are for reference data.
