The video looks to be the work of a paranoid conspiracy nut. RFID is inevitable technology. How it will be used and by who and when is up for debate, but it’s going to be a while before a significant number of people have them in their bodies or they become the main currency. But it will likely happen someday, and it won’t be all that scary.
As for modern use, I have an RFID chip in my ID for work, it’s great. I use it to get into the parking garage, the office, or another office across the country. And all I have to do is get my wallet close to the reader. In the parking lot I don’t even have to roll my window down, which is great when the weather is bad. I really should get one implanted in my dog in case he gets lost too. My wife has one for her parking garage too. It’s so much faster than even swiping a magnetic strip. My passport has one too, but I haven’t really seen any use for it from my standpoint yet. It didn’t speed me through passport control. Many people also have them in their credit cards, and probably don’t even know it. This can be a security issue, so if you know you have RFID in your credit card, you might want to get a shielded wallet. But remember, RFID has a very limited range, usually a few feet at most. It’s not like they can track it by satellite.
