Abstract

A reader (10) has a reader circuit (12) to read information from an article (14), which may be an RFID transponder. Several replaceable antennas (16) are provided. Means (20) are provided to identify a parameter of the corresponding antenna (16), such as resonant frequency, power capability etc. Control means (22) control the reader circuit (12) in dependence on the parameter recorded by the identification means (20) of an antenna (16) mounted on the circuit (12).
