Tourists Wrap Biometric Passports in Foil, Experts Warn of Damage

A new viral trend sees travelers wrapping their biometric passports in aluminum foil, ostensibly to prevent malicious digital scans and data theft. This practice, popularized on social media, stems from concerns about unauthorized RFID chip skimming.

Biometric passports contain an RFID chip storing sensitive personal information, including digital photos, names, birthdates, addresses, and fingerprints. While the technology allows for quick border control verification, proponents of the foil wrapping believe it can block radio frequency signals, citing the principle of a Faraday cage.

However, security and border control experts dismiss the practice as unnecessary and potentially harmful. They explain that the reading range of passport chips is very short, requiring close proximity or direct contact with a scanner. Furthermore, household aluminum foil is fragile, prone to tearing, and can create openings that negate its shielding effect.

Experts also warn that repeatedly folding and unfolding the foil can physically damage the sensitive electronic chip embedded in the passport's cover. This damage could render the passport unreadable, necessitating a costly and time-consuming reissue process. Israeli biometric passports, in particular, contain delicate components that could be compromised by such amateurish protection methods.

Authorities do not require additional protective measures beyond the standard passport. Experts emphasize that removing and reapplying the foil at border checks causes unnecessary delays and offers only a subjective sense of security. For those seeking genuine protection, specialized RFID-blocking sleeves are available on the market.
