Travelers Wrap Passports in Foil Amid Data Theft Fears, Experts Warn of Damage

A trend has emerged on social media where travelers are wrapping their passports in aluminum foil before flights, fearing unauthorized digital data theft. This practice stems from the fact that many modern biometric passports contain RFID chips storing sensitive personal information like photos, names, birthdates, addresses, and fingerprints. Proponents of the foil wrapping cite research suggesting that these passive chips can be read by nearby devices, and aluminum foil acts as a Faraday cage to block such signals. However, security and border control experts deem this DIY method ineffective and potentially harmful. They argue that the risk of unauthorized scanning during normal travel is extremely low, as it requires a reader to be very close to the passport. Furthermore, ordinary aluminum foil is flimsy and prone to tearing, creating gaps that could allow signals to pass through. For Israeli biometric passport holders, the practice poses additional risks. The electronic component in the passport's cover, designed for quick scanning at automated gates, could be damaged by repeated folding, pressure, and the foil itself. Such damage can lead to the passport being unreadable, requiring a costly replacement and potentially disrupting travel plans. Immigration authorities do not mandate extra protection beyond the standard passport. Experts suggest that the constant application and removal of foil at checkpoints causes delays without providing significant security benefits, offering only a subjective sense of safety. For those concerned about RFID skimming, specialized, durable RFID-blocking sleeves are available as a safer alternative.
