Might be easier if everyone is inserted a micro chip under our forearm skin....like a dog's microchip.
That's a great idea. For amputees or people with weak arms, put the microchip implant on the forehead.
It should also be linked to your bank account, you can perform cashless transaction with it. Greatly reduces the chances of banking scams. No person is allowed to buy or sell without the microchip, ATMs and credit cards will be a thing of the past.
Your health/vaccination record, driver's license and passport information can also be securely stored on the chip.
Finally, next-gen GPS tracking should also be a feature. Tracking people within a proximity error of +/- 2 meters. And also detect the location depth e.g. mall's basement 1 vs mall's level 2.
Missing children or old folks with dementia will no longer be a problem, because you will know exactly where they are all the time. Cheating spouses will also be a thing of the past, you will know when he/she is all the time, no more secrets or playing cat-and-mouse games.
We already microchip our pets, and Apple 'Airtags' are going to be everywhere. No surprises for what's coming next.
