# Which RFID Wallets Actually Work ## Understanding RFID Protection Technology RFID-blocking wallets are designed to protect your contactless cards from unauthorized scanning. Through my personal experience with digital security, I've discovered that not all RFID wallets provide equal protection. I've tested numerous products and found that effectiveness depends on both materials and construction quality. ## How RFID Wallets Actually Work ### Technical Specifications of Effective RFID Protection For an RFID wallet to actually work, it must incorporate specific shielding materials. The most effective products use: - **Faraday cage construction** with multiple layers of metallic material - **Shielding material**: Typically copper, aluminum, or nickel-based alloys - **Shielding effectiveness**: Minimum 60dB attenuation at 13.56MHz (RFID frequency) - **Frequency blocking**: 125kHz to 2.4GHz range coverage - **Material thickness**: Minimum 0.1mm metallic layer **Technical parameters for reference** (specific measurements may vary by manufacturer): - Chip protection: ISO/IEC 14443 Type A & B, ISO/IEC 15693 - Shielding material density: ≥65g/m² - Layer composition: 3-layer laminate (outer fabric, metallic shield, inner lining) - Dimensions of shielding layer: Must exceed card dimensions by at least 10mm on all sides *Note: These technical parameters are reference data.

My testing methodology involves using an RFID reader at varying distances to determine the true protective capabilities of each wallet. I discovered that my ability to distinguish between marketing claims and actual performance became a valuable skill. This analytical approach helped me identify three key factors that determine whether an RFID wallet will actually work: material quality, complete enclosure design, and proper seam construction. ## Top-Performing RFID Wallets That Actually Work ### Premium Options That Actually Work **TIANJ
