I think this kind of biometric immigration verification will come to many countries eventually. Like UK, Japan and USA already tested this kind of procedure and Singapore is just one step ahead with this full implementation. So, we just can't avoid it. If this kind of verification concerns you a lot just don't travel abroad.
Singapore isn't one step ahead, it's full-on surveillance state.
The implications here are that if you go through this process, then these biometrics will bought and sold throughout the world. You'll be tracked absolutely everywhere.
But it is the same if you have a regular (non-anonymous) social media account.
You can choose not to use social media... the choice is way harder for avoiding plane travel unless you can afford the time and money to use other means, which most people don't.
