The chips are to be placed behind the labels of factory bottles of CII meds to track their movements from manufacturer to local pharmacy...the amber vials that pharmacists generally use will NOT contain any sort of chip that could "follow" the end-user home. This technology has dual purposes - to ensure that CII meds are not being diverted somewhere along the supply chain & to ensure that meds received at more local levels (distribution warehouses, pharmacies)are not counterfeit after a recent rash of fake Lipitor & other drugs made it onto the legitimate market .
