Becoming more commonplace.. a MARK in place..
"Around 3,000 people in Sweden have had microchips embedded into their hands, AFP reports."
"The chips, which are only about as small as a grain of rice, are designed to hold entry keys, credit card information, access to vending machines and printers, and technology to collect train fair while the passenger is already on-board."

"It also forced all people, great and small, rich and poor, free and slave, to receive a mark on their right hands or on their foreheads, so that they could not buy or sell unless they had the mark, which is the name of the beast or the number of its name." - Rev. 3:16,17
