If your passport consistently fails to scan at 2026 e-gates or via mobile apps, the most common culprit is a damaged or misaligned RFID chip. These chips are embedded in the back cover or the photo page and can be corrupted by strong magnets, extreme heat, or excessive bending of the passport booklet. Another frequent issue in 2026 is NFC (Near Field Communication) interference; if you are trying to scan with a phone, your case or other cards (like credit cards) may block the signal. Furthermore, digital scanners at airports are highly sensitive to glare and lighting; if your photo page has a smudge or a reflective protective sleeve, the Optical Character Recognition (OCR) will fail. For 2026 travelers, if your chip is dead, you must replace the passport entirely, as e-gates are becoming the "mandatory" standard for entry in many countries to reduce the human bottleneck at immigration counters.
