The critter chips have a range on the order of a foot or less. I
mention this if you've got visions of being able to fire up some
electronics and locate your stolen property from miles away on a radar-
type screen, ala Hollywood. They are also radio-based, which means
that they can't be hidden inside anything metal. The radio waves have
to be able to reach the chip in order to power it up and send a signal
out. Search on "RFID". The chip will last as long as the critter.

The current popular labeling method for parts is to use a 2D square
digital ID code burned into surfaces with lasers, There are table/
phone apps that can read them. A very cheap method, as labeling
technologies go. Gun serials used to be stamped, now new guns have
mostly laser-burned ones along with the 2D code.
