e-gate is bio passport right?there are 2 queues: one for citizens and one for foreigners. the foreigners queue has 2 types of clearance: e-gate (default) and manned counters. i noticed some foreigners are automatically directed to manned counters by customs officers. i guess certain nationalities cannot use the e-gate. i used the e-gate and got thru' with no fuss.
or e-gate needs a particular card holder? while i was there, there was a board that says only if u hold a certain card
