An embodiment of the present invention provides a method for reading and writing data of a non-contact storage unit, a method for producing a non-contact chip, and a method for producing a non-contact chip card. The method for reading and writing data of a non-contact storage unit includes: The card reader is physically connected; data transmission between the contactless storage unit and the contactless card reader is performed through the physical connection. Through the data reading and writing method provided by the embodiment of the present invention, when realizing mass production of non-contact chips, each non-contact storage unit will not interfere with each other, which can ensure the stability and reliability of data reading and writing, and improve the qualification of products. rate, thereby reducing production costs and increasing production efficiency.
Description
technical field [0001] The invention relates to the technical field of non-contact chip cards, in particular to a data reading and writing method of a non-contact storage unit, a production method of a non-contact chip and a production method of a non-contact chip card. Background technique [0002] Contactless chip card is a portable storage medium, which is widely used in information identification of bank cards, second-generation ID cards, resident health cards and other applications. The data reading and writing of the contactless chip card is realized through the contactless card reader. Both the non-contact card reader and the non-contact chip card are equipped with a radio frequency circuit, the radio frequency circuit includes a matching capacitor and an antenna, and the operating frequency of the two radio frequency circuits is the same, so that under the excitation of the electromagnetic wave sent by the non-contact card reader, the non-contact The RF circuit in t...
