(Revelation 13:16-18) . . .And it puts under compulsion all persons, the small and the great, and the rich and the poor, and the free and the slaves, that they should give these a mark in their right hand or upon their forehead, 17 and that nobody might be able to buy or sell except a person having the mark, the name of the wild beast or the number of its name. 18 Here is where wisdom comes in: Let the one that has intelligence calculate the number of the wild beast, for it is a man’s number; and its number is six hundred and sixty-six.Yet to work, such a chip would need to be truly universal and account for potential obsolescence. My own flirtation with implanted technology came to an end when I moved away from London, making an Oyster-equipped hand pointless. Even with a return to London on the cards, I’m thinking twice about returning to my project, since Oyster cards are being phased out.
Such a development may actually be a cause for optimism for implant enthusiasts, however, because instead of Oyster cards, London's transport authority is allowing people to ride the subways and buses using bank cards. It marks the beginnings of a slow move toward a world where everything will be accessed from a single RFID microchip. If that day comes, I can’t think of a safer place to keep it than inside my own body.

Incidentally - the article refers to 'using bank cards' - it is only rumours but there is talk that the banks - all of them have gone - today (Sun 13th July 2021). I don't know what is supposed to have happened but if they have it might mean crypto currency will become the new way of securing loans.
