Chinese firm Yitu, which recently opened its first international office in Singapore, told Reuters it was in discussions with Changi Airport Group. Yitu says its facial recognition platform is capable of identifying more than 1.8 billion faces in less than three seconds.
Changi's newest terminal, T4, already uses facial recognition technology to offer self-service options at check-in, bag drop, immigration and boarding.
The technology means there are fewer queues and fewer visible airport or security staff.
Luggage is dropped at unmanned booths that take your photo and match it against your passport. You are snapped again at an automated security gate at immigration - a picture that is used to verify your identity at the boarding gate.
Changi is exploring how facial recognition can be implemented in its three older terminals for automated bag drop and immigration.
The airport sees T4 as a test bed for its fifth terminal, which will be up and running in about a decade.
"Today you take passport, you show your face and you show your boarding pass," said Lee, adding it may, however, be possible to use biometrics instead.
"Then actually in the future, you just take your face. You don't need your passport," he said.
