The only way it moves if not properly placed. Appears that it's rare from q/a that this happens. Micro chipping is still safe thing to do.

See link microchip placement

Can the microchip move around once inside the body of the animal?

When properly implanted, a small layer of connective tissue forms around the microchip, preventing movement or migration of the chip. Instructions and injection sites will vary depending upon the specie. As with any brand of chip, AVID® microchips will not migrate if instructions are followed and implantation is correct.
