Abstract:
A radio frequency management device includes a microprocessor, output devices connected in parallel to the microprocessor, reading units respectively connected to the output devices, each reading unit comprising an antenna coil, a blocking coil, a radio frequency driver module for driving the antenna coil, and a blocking driver module for driving said blocking coil to shield the antenna coil from the radio frequency driver module, and a reading and writing device connected to the microprocessor. The microprocessor controls the output devices in such a manner that only one radio frequency driver module is activated to drive the associated antenna coil at any time while the other antenna coils of the other reading units are shielded from the associated radio frequency driver modules by the associated blocking coils; the reading units are processed one after another in a proper order.
