This video shares how this RFID Microchip's battery has a self recharging mechanism built into it that operates by temperature fluctuations in the body. They found that the back of the hand, and underneath the hairline on the forehead is the most ideal spots for frequent temperature fluctuations, the two spots where the Bible says the Mark of the Beast will go.

Furthermore, this RFID Chip uses lithium battery. A Doctor was asked what would happen if that lithium leaked into the body, and he said a terrible sore would appear in that spot.

This is what the book of Revelation says: "And the first(Angel) went, and poured out his vial on the earth; and there fell a noisome and grievous sore on the men which had the mark of the beast, and on them which worshipped his image."
