Vaccinated arm sets off pet microchip scanner - but unvaccinated arm doesn't!

This appears to be from a woman who works at some some sort of veterinary clinic. In any case, her non-vaccinated arm does not respond to the scanner but the vaccinated arm does. Comes up with an ID. Just like a tracked pet. I don't have pets and I was curious but sure enough, this identical scanner is "a universal portable reader for RFID microchips with the purpose of identifying animals." and "When a microchip is detected, the WorldScan sounds a beep and the unique microchip identification number is displayed in an LCD window. Battery life is extended by the auto shut off feature. Includes wrist strap and handy sample 'test' chip!" https://www.ebay.com/itm/Home-....Again-Worldscan-Pet-
PS. I realize some may claim she's hiding a microchip under her shirt. While that's theoretically possible, given the videos I've seen (and posted) including blue-tooth connectivity and 5G and also EMF detectors with vaccinated people, I believe this is real.
