The only rule involved in the rfid bullets, is that it’s a threshold 2 to wipe them. That’s it. Otherwise it’s a small paragraph in a sidebar about yet one more way the corps try to control and own every single little thing, no matter how small or insignificant.
There is not rule in how much info it broadcasts, the signal strength, how to tell if someone is listening for it, nothing. It reads like a small fluff ammo-related fluff piece with a single stat for the inevitable question that will come up if mentioned in game.
Also, we already had RFID tagged gear, and matrix ownership link to equipment since fourth edition. This issue isn’t new, it’s just showed up in a new place.
