Do you need to scan your passport at the biometric self-check kiosk when entering Da Nang airport visa-free?

Travelers report that the biometric kiosk is supposed to be active, but in practice it often doesn't work — over time only about 1-2 people have reported getting any response from it.

A traveler who just landed said no one was asked to scan their passport at immigration. But warned rules could change anytime, so it's safer to go through the kiosk scan anyway — takes at most 5 minutes.

When filling out the immigration form, if entering on a visa-free stamp (not a visa), select the separate 'unilateral visa exemption' option.

Your passport must be scanned at the biometric kiosk — like scanning a barcode at a store checkout. If it wasn't scanned, it simply wasn't required in your case.
