Abstract

The invention discloses a radio frequency card and a working method thereof. The radio frequency card comprises a signal selector, at least three chips, input coils corresponding to the chips and output coils corresponding to the chips; the signal selector is connected with the input coils and the chips; the output coils are connected with the chips; and the signal selector is used for sequentially controlling the at least one chip to be connected with the corresponding input coils according to a sequence of preset chip priorities based on the preset chip priorities corresponding to the chip numbers of the at least one chip, so that the chip corresponding to the current preset chip priority is enabled to work under the action of a first induction voltage output by the corresponding input coil, until the chip corresponding to the current preset chip priority sends data to a card reader successfully. The radio frequency card is multifunctional, so that the problem of inconvenient life ofa user due to single function of the card is solved, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of smart cards, in particular to a radio frequency card and its working method. Background technique [0002] The contactless card (RFID card) is composed of a chip and an inductive antenna, which obtains energy and exchanges data through the induction of the antenna coil. At present, contactless cards are widely used in many fields, especially in the field of transportation. There are many kinds of non-contact protocols, among them, the protocols defined by international standards are Type A and Type B, and there are many other communication protocols in practical applications that have not been included in the international standards. Since different industry applications usually use different communication protocol standards, it is currently impossible to integrate these industry applications on one card. For example, the bus application in a city uses one communication protocol, and the micropayment in...
