This is something to be very afraid of. Forget the Mark of the Beast, this is the Beast's social credit score system being birthed. Think the Chinese social credit system on steroids.
It will start innocuously, as it has now, but it will slowly morph into a way of (a) indelibly identifying each individual, and (b) providing access to all of the information the government thinks that individual should be required to provide to third parties (including hackers, because this sh*t always ends up getting hacked).
Eventually, one will have to link up with government-controlled/sanctioned computers, probably on a daily basis, to get your social "credit score" updated, and if you don't, the implant will provide a simple "invalid" flag to anyone who reads it, and you will be denied all manner of goods and services - not just charity, like government benefits, but normal private commercial transactions - until you link with the government computers to get updated.
I'm not a particularly religious person, but this certainly smacks of the Mark of the Beast from Revelations.
