SECURITY FOR BLISTER PACKS

摘要

Various RFID based blister pack embodiments are provided for improving the ability to detect and prevent tampering and counterfeiting of blister packs and/or facilitating the chain of custody tracking of blister packs during manufacture. Some embodiments employ an RFID chip network on the blister pack and some embodiments employ an RFID strap network on the blister pack , wherein the integrity of the network (or lack thereof) is used to indicate the possibility of tampering. Other embodiments determine the possibility of tampering based on the frequency of an RF signal that is received from a chip provided on the blister pack, which will vary depending on whether the associated antenna has been detuned as a result of some type of tampering.
