Filed: 1990-04-02
Abstract: PURPOSE: To enable a transaction by detecting whether the level of the pulse of radio frequency exceeds a threshold level or not and to display as to that a token is located in an inductive neighborhood when the level does not exceed the threshold level. CONSTITUTION: This system is constituted of means 1, 2, 4 generating and transmitting pulses of radio frequency, means 2, 3 detecting whether the level of the pulses exceeds a threshold level in a prescribed period equal to or shorter than the duration of the pulses or not, and a means 7 displaying that a token 6 is located in the inductive neighborhood when the level of the pulses does not exceeds the threshold level under this condition. Consequently, when the carrier RF signal is generated in pulse and the token 6 comes into the neighborhood of a terminal, the level of radio frequency field is made to be lowered. Thus, since the location of the token 6 is detected by using the condition that the level of the RF in specified pulses does not exceed the threshold level, the execution of the transaction is made possible by holding the RF in an ON- state perpetually.
