Methods and apparatus for medicament tracking are disclosed herein. In one embodiment, medicaments are initially stored within secure medicament containers. One or more containers comprise a radio frequency identification module or another electromagnetic transmitter adapted to generate tracking signals. Optionally, the tracking signals may be transmitted according to one or more anti-collision protocols in order to reduce and/or prevent interference with other transmitted signals. Electromagnetic readers situated at one or more locations verify when the medicament containers are proximate to those readers. In some embodiments, once the medicament containers have successfully been tracked to a target location, inventory and tracking data may be updated within one or more external devices.
