What do you think about this RFID chip?

In case you don’t know, the RFID chip is a small chip the size of a grain of rice that people are getting implanted in their hands. They’re doing it for little conveniences like scanning to open up your front door to your house. But I think eventually so many people will have it that you will need it to buy or sell, and it will contain all your financial information on it. Some people think it’s the Mark of the Beast.
