Protocol conversion paster of radio-frequency card reader and method for transmitting data with paster

Abstract

The invention discloses a protocol conversion paster of a radio-frequency card reader and a method for transmitting data with the paster. The paster comprises an adhesive layer, a first antenna layer (304), a protocol conversion circuit, a card swiping face, second antenna layers (301) and a signal shielding material (302), wherein the adhesive layer and the first antenna layer (304) are adhered to the radio-frequency card reader to obtain radio-frequency signals and transmitting radio-frequency signals to the protocol conversion circuit, the protocol conversion circuit conducts protocol conversion on data transmitted between the radio-frequency card reader and a card, the card swiping face and the second antenna layer (301) communicate with the card to be read and transmit response signals to the protocol conversion circuit, and signal shielding materials (302) are arranged between the card swiping face and the second antenna layer (301) and between the adhesive layer and the first antenna layer (304) and wrap the protocol conversion circuit. By the aid of the protocol conversion paster, signals can be switched among different protocols without any modification of hardware or software of original terminal devices.

Description

technical field [0001] The invention relates to the field of radio frequency card reader protocol conversion, in particular to a sticker capable of converting or expanding the protocol used by the radio frequency card reader into a new protocol and a data transmission method using the sticker. Background technique [0002] With the development of society, contactless cards are more and more widely used in daily life. In many occasions, contactless card swiping operations, such as access control, public transportation, petty cash payment for catering, etc., have become a part of people's daily life. part. However, in the application of contactless cards, there are many different protocols such as Type A, B, C (Felica) and Mifare, or the same communication protocol, the minimum transmission power of the card reader device required by the application is not exactly the same Format problem. Since general card readers can only be used with cards that use the same protocol and t...

Problems solved by technology

Since the conversion device needs to be connected with the digital interface in the card reader, it is not only necessary to modify the hardware of the card reader, modify the interface circuit connection, etc., but also need to partially modify the software to meet the requirements of communication with the conversion device. At the same time, in practical applications, due to the newly added circuits and devices, the original card reader shell or installation position needs to be adjusted, which brings certain difficulties to the transformation of the card reader.
