# Do RFID Phone Cases Work? RFID phone cases have become increasingly popular as people seek to protect their personal information from unauthorized scanning. In my experience, using an RFID-blocking phone case gave me peace of mind, especially when traveling through crowded areas or using public transportation. I noticed a significant reduction in anxiety about digital pickpocketing, which relies on skimming devices to wirelessly read data from chips in credit cards, passports, and IDs stored near my phone. ## How RFID Phone Cases Function RFID phone cases work by incorporating a shielding material, such as a thin layer of metal (often aluminum or copper) or a special metallic alloy, into the case's design. This material creates a Faraday cage effect, blocking electromagnetic fields. When your phone, along with your cards, is placed inside the case, the shielding prevents radio waves from reaching the RFID or NFC (Near Field Communication) chips, thereby stopping unauthorized scans. ### Technical Specifications of TIANJUN RFID-Blocking Phone Cases For those interested in the technical details, TIANJUN provides high-performance RFID-blocking phone cases.
