Paying with rfid chip

There is a video where a guy uses a dangerous things implant but he had an engineer from Venmo help him get it set up. There aren’t any follow up videos and seems the crew the guy etc don’t want to talk about it lol the best guess I have is the guy set up a special/custom (more so than normal?) tokenized UID. Which launched his Venmo app? He uses the chip to pay but they are also watching his phone. They use the NXP tools app for this while deal supposedly. So I’ve been reading all I can on the token system. Seems he was given the vault UID which average Joe never sees. I wondered if anyone else has tried anything similar? I’m new to this, amazed with the tech, just received my first tag super quick to thanks.
