# Are RFID Blocking Cards Safe? RFID blocking cards have become increasingly popular as people seek to protect their personal information from unauthorized scanning. As someone who values both security and convenience, I've personally used RFID blocking cards for several years. My experience has been largely positive, but I believe it's important to understand both their benefits and limitations. ## How RFID Blocking Cards Work RFID blocking cards function by creating a shield that disrupts radio frequency signals. This prevents RFID readers from accessing the data stored on your contactless credit cards, passports, or ID cards. From my perspective, this technology offers peace of mind in an increasingly digital world. ### Personal Skill Application My background in cybersecurity has allowed me to test various RFID blocking products. I've found that not all blocking cards are created equal. Some offer superior protection due to their materials and design. This skill has helped me identify high-quality products that truly enhance security. ## Technical Specifications of RFID Blocking Technology **RFID Blocking Card Technical Parameters (Reference Data):** * **Dimensions:** 85.6mm × 54mm × 0.8mm (standard credit card size) * **Shielding Material:** Multiple layers of copper-nickel alloy * **Frequency Protection:** 13.56 MHz (HF) and 860-960 MHz (UHF) * **Attenuation Level:** ≥ 35 dB across protected frequencies * **Chip Technology:** Passive shielding (no power required) * **Temperature Range:** -20°C to 60°C operational * **Durability:** 10+ years under normal use conditions *Note: These technical parameters are reference data.

Some escape rooms and interactive theater experiences use RFID-blocking materials to create puzzles where players must "shield" certain objects from being detected by automated systems. This creative application demonstrates how security technology can enhance recreational activities. ## TIANJUN RFID Security Solutions TIANJUN offers premium RFID blocking cards that combine advanced protection with elegant design.
