Embodiment Construction

[0009] In the present invention, a controllable switch is connected in series between the coil and the integrated circuit. By controlling the controllable switch, the working state of the radio frequency IC card can be controlled. In addition, the controllable switch is controlled by an intelligent control circuit with information processing and control functions. , you can implement intelligent program control on the radio frequency IC card.

[0010] The communication circuit is used for communicating with external management equipment, receiving control commands input from the external management equipment, or uploading saved record information to the external management equipment. The detection circuit is used to generate a monitoring signal for processing by the intelligent control circuit, and the monitoring signal reflects whether the device of the present invention worn on the user's body is detached from the user's body.

[0011] The intelligent control circuit can con...

Abstract

The invention provides a radio-frequency multi-functional intelligent card which relates to an IC card, in particular to a combined type radio-frequency IC card of which the working state is controlled in an intelligent way. Because the working state of the prior radio-frequency IC card can not be controlled, the prior radio-frequency IC card can not meet certain special applications. The invention aims to provide a novel radio-frequency IC card which combines an intelligent control circuit and a traditional radio-frequency IC card into a whole. The intelligent control circuit, a communication circuit, a detection circuit and the radio-frequency IC card are combined into a whole, the radio-frequency IC card comprises two parts: a coil and an integrated circuit, and the coil is also an antenna of the radio-frequency IC card and is used for transmitting and receiving electronic data.

Description

technical field [0001] The invention relates to an IC card, in particular to a combined radio frequency IC card whose working state is intelligently controlled. Background technique [0002] The radio frequency IC card has many advantages and has been widely used in people's daily life. However, in some application projects, it is necessary to control the working state of the radio frequency IC card. For example, in the application of the radio frequency IC card door lock system, if the radio frequency IC card used as the key card is lost or cheated, it may be used by misbehavior and cause property loss. For another example, in the application of the radio frequency card electronic patrol management system, the patrol personnel are assigned a radio frequency IC card used to represent their identity, but this card has no restraint function on the carrier, and the patrol personnel can arbitrarily put their identity The card is handed over to others instead of clocking in, res...
