Identification.
A pierced ear with a tag slotted into it, a notched horn to indicate something to those in the know, a thin collar like a hospital band made of bright plastic or fabric, a metal shackle with no place to put chains, only engraved with information like a bird's band.
YES IDENTIFICATION TAGS!
My dude has a gold-plated ear cuff pierced through his ear (and permanently melted closed) with a stamped “M” on it, an arm tattoo with his facility-given ID number, and multiple trackers embedded in his neck and spinal column (in areas where he can't cut them out)—you know, because you can never be too careful when it comes to securing the whereabouts of such a pricey asset!
