I was taught never to get anything like this installed in me since it’s almost definitely the mark of the beast. Eventually no one will be allowed to buy anything unless they have these high tech devices in their hands

“Also it causes all, both small and great, both rich and poor, both free and slave, to be marked on the right hand or the forehead, so that no one can buy or sell unless he has the mark, that is, the name of the beast or the number of its name.” - Revelation 13:16-17

I’m not a Christian anymore, so I don’t believe this. Looking back, I actually think I find it a bit silly. But that’s what that other guy means
