Abstract
A contactless communication device comprises a contactless front chip, a security chip concentrator and a security chipset. Wherein, said security chipset contains more than two security chips for storing and processing the contactless application data; said contactless front chip is used for implementing the interaction between said security chip and the external contactless field; said security chip concentrator, which is connected with the contactless front chip and with the security chip of the security chipset, is used for selecting a security chip based on the contactless application and implementing the connection between the selected security chip and the contactless front chip. The contactless communication device of the present invention is based on the application mode of multi-card for multi-use so that different providers can independently issue security chips separated from the contactless communication device, then the problems of data security, user management and so on caused by single-card for multi-use are avoided.
