Mrt definitely can. Setup counter in front of gantry, jab status clear liao then can tap in.

Bus will be a bit difficult.. What they can do, is like check for fare evader.. Send conductor to conduct regular check on vaccination status, and kick the person off the bus if no jab.

No way lah. Ah Leong talk cock.

Hawker ctr can do it because people can still tah pao food. 

You don't let them take public transport so all take taxi? Or taxi also cannot? 

Might as well say CB for unvaxxed , better.
