Problems solved by technology

Using two separate systems and two chips, it is impossible to simulate the switching process between one chip and the user program in the dual-interface smart card product card with the switching of the two card readers between the two working modes
It is also impossible to simulate the existence of both card readers. The chip can work in both contact mode and non-contact mode, and which mode it actually works in is determined by the user program.

Embodiment Construction

[0015] As shown in the figure, the dual-interface smart card emulation card 1 mainly includes an emulation chip 2, a program memory 3, an antenna 4 (non-contact interface), and a contact 5 (contact interface). The emulation chip 2 includes various functions of the product chip. The dummy chip 2 is connected to the contact 5 through a contact channel 10 and connected to the antenna 4 through a non-contact channel 11 . The program memory 3 stores the user program. During operation, the emulation chip 2 can read the user program therein through the program reading bus 9, and the user program can be repeatedly burned. The contact 5 is a contact conforming to the ISO 7816 standard, and the 7816 signal on the contact 5 is connected to the contact card reader 6 through the wired channel 12 . The antenna 4 is an antenna similar to that on the product card, and communicates with the antenna 8 of the contactless card reader 7 through a wireless channel 13 through a carrier signal.

Abstract

This invention discloses a kind of double boundary intellect card simulate card which includes a simulate slug, a program memory device. When working the simulate slug fetches the user program in the program memory device by the program among that it also includes the contact interface and the non-contact interface connecting with the simulate slug. The contact interface is a contactor according to the ISO 7816 standard and connects with the contact card reader by the 7816 signal on the contactor; the non-contact interface is a wire similar with the wire in the production card and connects with the wire of non-contact card reader by the carrier signal.

Description

technical field [0001] The invention relates to a dual-interface smart card emulation card, in particular to a dual-interface smart card emulation card used in the testing and authentication process of user programs in the dual-interface smart card. Background technique [0002] Dual-interface smart card is a new kind of smart card, which is a combination of contact smart card and non-contact smart card. Switch between the two modes. [0003] The user program in the dual-interface smart card is usually masked when the chip is produced, and the user program cannot be modified after the production is completed. Therefore, in order to reduce production risks, the user program must be masked before masking. Rigorously tested and certified to ensure its correctness. [0004] In the writing and debugging of user programs, the tools used are generally dual-interface smart card emulators with contact card readers and non-contact card readers. But the dual-interface smart card emu...
