Method and device for exchanging information

摘要

Method for exchanging information between a central information unit (1) and a person or an object by use of short range radio signaling, e.g. Bluetooth (RTM). Accordingly an identification signal is transmitted from a radio module to a receiver unit (4), from where it is transferred to the central information unit, which processes the identification signal and produces an output signal, which is transmitted to an output unit. The invention also relates to a corresponding device for method implementation.
