This guy implanted an RFID chip in his hand.
"Well, the RFID chip is finally in. Now it's time to get on with buying a house that I can deck out with RFID sensors. But, probably before I get a chance to do that, I'm going to put a sensor in my car door. One small step for hand, one giant leap for keyless entry. Another thing I'm going to work on is figuring out how to write a custom GINA for Windows and putting a sensor into my keyboard so when I place my hands on it, the system will automatically log me in."http://www.rfidnews.org/weblog/2005/03/24/man-implants-tag-in-hand/
(Revelation 20:4) And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.
