发明名称 RFID tag
摘要 An RFID tag comprising a coil and an RFID chip having two inputs/outputs, each input/output being connected to the coil. The tag further comprises an electrical circuit connected to the inputs/outputs, the circuit being adapted to operate in one of two modes, one mode outputting substantially no signal whereby the RFID chip is allowed to operate and a second mode being a mode wherein a signal is output so that the operation of the RFID-chip is interrupted. Alternatively, the circuit may have a lower operating voltage than the RFID-chip and may thus starve the RFID-chip and prevent its operation when desired.

主权项 1. An RFID tag comprising: a coil; an RFID chip having two inputs/outputs, each input/output being connected to the coil; an electrical circuit directly connected to the coil and the two inputs/outputs, the electrical circuit being configured to operate in one of a first mode and a second mode, the first mode being a mode wherein substantially no signal is output to the two input/outputs, the second mode being a mode wherein a scrambling signal is output to the two inputs/outputs; and a switch configured to control in which of the first and second mode the electrical circuit operates in.
