Nothing hard to understand at all. My point is that you can take out the battery and still be able to check in, which makes the entire thing looks dumb.
Because you are not just checking in.. you are also doing contact tracing.. the token can do that.. your nric can't..
Scanning nric only logs where you went and what time.. the token captures who you came into contact with while you were there.
Is that so hard to understand?
