<p>Location of contacts between persons connected by leads involves a system of lead tracing and location in communication apparatus. A lead is identified with a unique code and this code is then coupled to a traceable and locatable communication apparatus, such as a telephone. The lead without being visually recognizable is technically traced and located. Also, a lead, without the intermediary of the system, by means of data transmission wireless techniques, such as Bluetooth, can trace leads through the unique codes in the adjacent ambiance by intercepting them from communication apparatus.</p> |
