This is one of the tennets of the "Great Reset" and has been discussed numerous times.
The end goal for that particular one is that in order to access the internet you will have to authenticate via biometric digital ID every time you hop on. Technically this is already achievable and easy to implement.
They just need a big crisis to nudge people into it.
My take, is that a major "cyberattack on banks" will be the ticket for that particular one.
