Abstract: Tamper detection on an article is performed by reading data from an RFID tag having an antenna with segments designed to break apart. The RFID tag is secured to the article in such a way that, when the article is tampered with, the antenna segments will break apart. Detachment would decrease the reading range of the RFID tag. An RFID reader may be used to read the data from the RFID tag. The predefined reading range (Rp) of the RFID tag, with antenna segments entact, is obtained from the data which was read by the RFID reader. The RFID reader obtains the data while located at an actual reading range (Ra) relative to the RFID tag. By comparing Ra with Rp, it is determined whether the antenna is still entact. If Ra<Rp, the antenna is likely to be broken apart, thereby indicating that the article has been tampered with.

The drug delivery device includes a machine readable code and a visual indicator, and has pre-use and used states, such that use of the drug delivery device triggers a transition from the pre-use to the used state. The visual indicator has a first state when the drug delivery device is in the pre-use state and a different second state when the drug delivery device is in the used state. The method includes enabling a user device having an image sensor to capture an image of the drug delivery device, determining, by the user device processor from the captured image, whether the visual indicator of the drug delivery device is in the second state, and obtaining, by the processor, information from the machine readable code when the visual indicator is determined to be in the second state.
