“Could RFID technology be used to become the mark of the beast? Why or why not?” Understand that this post is an intersection of Theology and Technology question. You cannot answer this post without considering both.
Technology can be used for good. Think of all medical devices that have saved countless lives over the decades.
Technology can also be used for evil. Think of how technology can be used to manufacture biological weapons and mind-altering drugs or to facilitate kidnapping, human trafficking, and even murder.
In the hands of good people, any technological device can be used for good. In the hands of evil people, the same device can be used for evil. Thus, it is true for RFIDs.
Some people have suggested different uses for RFIDs, including the tracking of humans through the use of chip implants beneath the skin. For all of the benefits that this potentially brings, could there be hidden dangers as well? Some people have likened embedded RFIDs in humans to the mark of the beast as described in Revelation 13:17 (NIV): “And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name.”
