摘要
A system comprising multiple reading devices which are arranged for wireless readout of at least two different types of transponders, each reading device being arranged for generating, in use, a time-repetitive electromagnetic interrogation transmission pulse. The pulse duration has a predetermined first value (ΔT) and the quiescent period between two successive interrogation transmission pulses has a predetermined second value ΔR when the reading device does not receive a response. The first value of the reading device is prolonged when the reading device receives a response from at least one transponder of a first type, and the second value of the reading device is prolonged when the reading device, in between the transmission of two interrogation transmission pulses, receives a response from at least one transponder of a second type. The reading devices are connected with each other through a synchronization connection.
