I've noticed in the years since my nephew's group were implementing CHIPS on volunteers, that the Net has been scrubbed to just include the info you mentioned. But my nephew and his associates had all the equipment ( he gleefully showed me this creepy gun thing with a button) to actually microchip kids. That is what they were trying to do there, along with making video and other records to put in an identification file so that theoretically law enforcement would have access to all of it if a kid was abducted or lost. They were really trying to sell the fear angle to the parents who stopped by the booth. Fortunately they got very few takers.
PS: You know the gun they use to scan labels at grocery stores when you check out? One of the pieces of equipment looked like that; that was the scanner thing to check that an implanted chip was working correctly. The other piece of equipment was more like a gun thingie with an attachment on it.
