a system for object tracking may comprise at least one subsystem that couples an electronic signal emitting and receiving device to an object to be tracked , at least one subsystem that assigns an identifier to the object , at least one subsystem that registers the identifier of the object with a second object , and at least one subsystem that establishes electronic communication between the object to be tracked and the second object via the electronic signal emitting and receiving device . also a system for object tracking may comprise at least one subsystem that detects at a first object an electronic signal from a second object , and at least one subsystem that emits an electronic alert beacon from the first object when said first object is determined to be out of range of the second object .
