There is provided an identification band configured to be associated with a wearer. The identification band comprises a first band transceiver configured to receive a first profile of the wearer; a memory configured to store the first profile; and a sentinel circuit configured to detect removal of the identification band from the wearer and to detect reattachment of the identification band; wherein the identification band configured to dissociate from the wearer if the sentinel circuit detects removal of the identification band from the wearer, the identification band further configured to re-associate to the wearer if the sentinel circuit detects reattachment of the identification band. The identification band may dissociate from the wearer by invalidating the first profile stored in the memory, and the identification band may re-associate to the wearer upon receiving a second profile that uniquely identifies the first profile.
