Fig. 2 is anti-theft device principle schematic in the utility model Fig. 1.
Embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Fig. 1 is IC-card illegal device schematic diagram in the utility model one embodiment.
As shown in Figure 1, in the utility model embodiment, IC-card illegal device comprises virtual protection circuit 10, IC-card chip 20, radio communication (Radio Frequency, RF) module 30 and power supply 40.Wherein:
Virtual protection circuit 10 connects IC-card chip 20, radio communication RF module 30 and power supply 40, for managing the unlatching of radio communication RF module or closing.
Radio communication RF module connects virtual protection circuit 10 and IC-card chip, the unblanking sending for receive logic holding circuit 10 or close RF communication function.
Power supply 40 connects virtual protection circuit, for the normal work of virtual protection circuit.When power supply 40 electric weight exhaust or occur extremely causing can not normal power supply time, virtual protection circuit 10 automated closed-loops, radio communication RF module is held open state, ensures that the communication function of IC-card can normally use.
In the time that IC-card chip 20 need to be worked, virtual protection circuit 10 is opened radio communication RF module, and at this moment the communication function of IC-card can normally be worked; In the time that IC-card chip 20 need to quit work, virtual protection circuit is closed radio communication RF module, and at this moment the communication function of IC-card is not worked.
Fig. 2 is anti-theft device principle schematic in the utility model Fig. 1.
As shown in Figure 2, IC-card illegal device also comprises the first button 11 and the second separate room 12.Wherein:
The first button 11 connects virtual protection circuit 10, for transmitting control signal 110 to virtual protection circuit 10.In the time that virtual protection circuit receives the control signal 110 that the first button 11 sends, the contactless function that virtual protection circuit 10 is controlled radio communication RF module 30 and opened IC-card, realizes the normal work of IC-card.In the time that virtual protection circuit 10 does not receive the control signal that the first button 11 sends, virtual protection circuit 10 is controlled radio communication RF module 30 and closes the communication function of IC-card, and both IC-card was closed contactless function.
