Effect of thumb flexion / extension on RFID implant range

I wanted to post this video to show just how the body’s own tissue interferes with an RFID implant’s ability to be read, even with a high power reader. These tags have very low read range due to their size, and the location I chose between the thumb and index finger of the hand offers the most when it comes to protection of the tag from blunt force as well as consensual reading and position manipulation (I can get the tag close to a reader by simply putting my hand up to it). Other implant locations do not offer this mix of protection and ease of use.

You can see from the video, when my thumb is fully adduced (closed), the RFID tag cannot be read. When it is fully abducted (open), the tag can be read.
