Embodiment Construction

[0037] In the following description, many specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways than those described here, so the present invention is not limited by the specific embodiments disclosed below.

[0038] As mentioned in the background art section, the contactless communication terminal in the existing near field communication technology usually adopts the one-card-multi-purpose technology or the dual-interface card technology. For the one-card multi-purpose technology, it is difficult to implement and manage multiple applications across operators; and for the dual-interface card technology, it is difficult to control the consistency of non-contact radio frequency performance of contactless communication terminals.

[0039] In view of the above problems, the inventors of the present invention have proposed a new type of non-contact front-end chip structure. By setting a secu...

Abstract

The invention relates to a safety chip concentrator loaded in a non-contact communication terminal. The safety chip concentrator comprises a plurality of non-contact application interfaces connected with the safety chip to realize connection between a safety chip group and a non-contact front-end chip, wherein the safety chip group comprises at least two safety chips. The safety chip concentrator ensures that one non-contact communication terminal can load a plurality of safety chips to meet different non-contact application requirements so as to greatly improve the possibility of a technology of the intelligent card application integration; the safety chip concentrator supports a single-wire protocol technology, thereby the non-contact communication terminal under the power-off state can still finish non-contact application and the application occasion of the non-contact application is greatly expanded.

Description

technical field [0001] The invention relates to the technical field of mobile communication, and more specifically, the invention relates to a safety chip hub for contactless communication. Background technique [0002] In recent years, with the rapid development of radio frequency identification (RFID) technology, electronic payment has penetrated into every aspect of daily life. Electronic payment usually adopts the form of smart cards such as credit cards and bus cards to realize the payment function. Electronic payment brings great convenience to people's daily life, especially in fixed business places. The smart card-based electronic payment service has formed a mature technology and a stable market. [0003] With the further development of electronic payment applications, the demand for combining smart card applications with mobile communication devices has begun to emerge: people hope that smart cards can have a display function, so that they can query the data infor...
