Somewhat related, Singapore also has a national digital ID system called Singpass[0] which is part of their Smart Nation[1] initiative. Once registered, you can use it from your PC/Phone for digital access to most government services.

You said "most government services" but eID is usable with all Estonian government services and a significant amount of private sector services.

I was sort of hedging my bets there w.r.t government services. Granted, it is comparatively less prevalent in private sector services.

Does Singpass use biometric (either for enrollment, or during each use of it)?

[noisy_boy]

It does utilize biometrics - face/fingerprint scan.
