Everyone’s iris is unique, unchangeable throughout the life, non-replicable, highly secure, and regarded as the “most reliable biometric identifier” aside from DNA. Iris recognition technology can effectively solve the problem of some passengers who are unable to use the automated passenger clearance service owing to their unreadable fingerprints. Using “My border crossing” QR code or the "QR Code for Hong Kong and Macao Clearance Service" with iris recognition allows passengers to enjoy completely contactless automated immigration clearance service. |
