Abstract
A tracking system is disclosed that enables the tracking of a beacon device and a credential device being held by the beacon device. The beacon device may communicate with readers of an access control system using a first communication protocol whereas the credential device being held by the beacon device may communicate with readers of the access control system using a second communication protocol. As the beacon device and the credential device being held by the beacon device may also communicate with readers at different times, a beacon device may be associated with a credential device being held thereby such that tracking of one device enables inferred tracking of the other device.
