Here come the tattoo marks – Scientists want to stamp children with invisible ink to prove they’ve been vaccinated

Forget the tatoo, they've got something already that works.

My brother is a contract engineer on an army base in Maryland and they are replacing building entrance security scanners with models that will also detect if you have been vaccinated.

Now how do you think that will be done? These are electronic scanners so it will only work if you are already Marked with something from your vaccine.
