The meaning of the concepts of tracking and tracing is clarified, trying to avoid overlap and making them a complementary pair. Tracking and tracing systems are classified using eight attributes.

It is seen that most existing tracking and tracing systems are of a relatively simple type, but current plans and designs lead one to expect more advanced systems in the near future.
