PAX COMPUTER TECHNOLOGY (SHENZHEN) CO., LTD.

A tamper-proof structure and an electronic device are provided in the present application. The tamper-proof structure includes a first-order circuit board, at least one tamper-proof component, at least one safety signal wire and a security chip. The safety signal wire is wrapped around an outer layer of the first-order circuit board or penetrates through a through hole and is wrapped around an inner layer of the first-order circuit board to form a tamper-proof area as required. The safety signal wire is connected to a tamper-proof switch and the security chip correspondingly, and a level of the safety signal wire is changed when the tamper-proof switch or the safety signal wire is damaged, and the security chip is triggered to erase sensitive information accordingly. By punching on the first-order circuit board, an objective of tamper-proof and an objective of reduction of design cost and simplification of security solution are achieved simultaneously.

The present application provides a method for implementing a middleware based on EMV, a terminal device, and a computer-readable storage medium. The method includes: establishing a middleware based on EMV L2, wherein the middleware provides a first interface for an upper-layer application of the terminal device to call; after the middleware receives a calling request for the first interface sent by the upper-layer application according to detected information of a IC card, calling an interface of an Entry library according to the calling request to obtain a return result of the Entry library, wherein the return result of the Entry library comprises an application identifier of the IC card; and determining an EMV L2 library matching the IC card based on the application identifier, and calling an interface of the EMV L2 library matching the IC card, to complete a contactless process with the IC card.
