Why did the high-speed rail ticket machine reject my passport?.

Symptom: At a 12306 self-service kiosk you scan your passport and the screen shows "document not recognized" or no ticket prints.

Cause: Station kiosks read the passport MRZ strip via optical scanner; smudged, laminated, or older-format passports fail OCR, and some machines accept only mainland ID cards.

Fix: Go to the manual ticket counter with passport and order number, or use the 12306 mobile app with the e-ticket QR code and pass through the ID gate directly.
