A chip system loading method and a chip card

Abstract

The embodiment of the invention provides a chip system loading method and a chip card. When receiving the chip system loading request, each security chip judges that the chip system of the security chip cannot be loaded at present; detecting the current working mode of the chip card; when it is detected that the chip card is in a non-contact mode at present; and establishing working communicationwith first terminal equipment through the Bluetooth main control chip or the near-field communication chip, and receiving chip system updating information sent by the first terminal equipment according to the selection response information, thereby updating the chip system based on the chip system updating information. Thus, loading and updating of the chip system of the security chip are achievedthrough the non-contact mode, the applicability in the actual scene is higher, the problem that in the prior art, a user often needs to return a chip card back to a related card issuing mechanism tobe processed, and consequently much inconvenience is caused is solved, and the user experience is enhanced.

Description

technical field [0001] The present application relates to the field of chip cards, in particular to a method for loading a chip system and a chip card. Background technique [0002] The chip operating system COS (Chip Operating System) is the core of the chip card, which mainly controls the data exchange between the chip card and the outside world, and completes the processing of various commands in the card. The security chip (SecureElement, SE) in the chip card is usually provided in the form of a chip, and is equipped with the chip operating system COS to realize data security storage, encryption and decryption operations and other functions. In the prior art, after the chip card is selected, the corresponding equipment will be selected according to the chip card to load the COS. For example, the COS of the common chip card currently on the market adopts the international standard ISO / IEC 7816 protocol to load the COS through the contact method. to load. Therefore, beca...
