Transponder reading device and also control system for controlling the handling of transponder-bearing objects by means of transponder reading devices
First Claim
1. Control system for controlling the processing of transponder bearing objects by transponder reading devices respectively comprising,a device for transmitting information between a transponder and the transponder reading device by a frequency shift keying process in the high frequency range, and a microcontroller which is operated in a decentrally operating control network, wherein processing stations include the transponder reading devices which are jointly connected in the decentrally operating control network, characterized in that a transponder reading device. upon starting identification of or read-out of information from a transponder, asks other transponder reading devices of the control network located in the vicinity whether these other transponder reading devices are in operation, or informs these other transponder reading devices when it itself assumes operation.

Abstract
A transponder reading device and a control system for controlling the handling and/or processing of transponder-bearing objects by such transponder reading devices. The transponder reading device is equipped with its own microcontroller, and with its own control unit. The microcontroller is, as a component (node) of a control unit, able to communicate with other devices of the same design to exchange information. Consequently, several such devices can be operated simultaneously in a confined space without interfering with each other.
