The invention discloses a time sequence control method of a light-emitting intelligent card and an intelligent card. The method comprises the following steps: enabling a light-emitting time sequence control circuit to obtain electric energy through employing an antenna to sense a radio wave transmitted by an intelligent card reader-writer when the intelligent card and the wireless intelligent cardreader-writer carry out the reading and writing operation, and driving the card to work based on the electric energy; during work, using the control logic contained in the time sequence control circuit for controlling all the light-emitting light sources of the light-emitting device on the intelligent card to emit light according to a preset time sequence, and switching the light-emitting statesof the light sources by taking a plurality of clock periods as units according to the time sequence, wherein the light-emitting states of the light sources comprise light-emitting duration, light-emitting colors, flicker frequencies and light-emitting brightness of different light sources. According to the invention, while the original data read-write function of the light-emitting intelligent card is ensured, the light-emitting time sequence of the light-emitting devices on the card is controlled, and the data display function of the light-emitting intelligent card can be enhanced.
Description
Technical field [0001] The invention relates to the field of electronic technology, in particular to a method for controlling the timing of light emission of a smart card and a smart card. Background technique [0002] Smart cards, also known as IC cards, smart cards, microchip cards, etc., are dedicated integrated circuit chips embedded in a PVC (or ABS, etc.) plastic substrate conforming to the ISO7816 standard, and packaged into a card form similar in appearance to a magnetic card , Can also be packaged into special shapes such as buttons, keys, and accessories. Current smart cards can realize data interaction with RFID radio frequency readers by adding induction coils and related wireless signal modulation circuits, which are called RFID smart cards. This kind of RFID smart card generally does not have a battery itself, and relies on the electromagnetic energy sent by the card reader to work. Its structure is simple, economical and practical, and thus it is widely used. Pas...
