Universal encrypted magnetic head module

Abstract

The invention discloses a universal encrypted magnetic head module. The universal encrypted magnetic head module comprises a hard printed circuit board; the hard printed circuit board is provided withan information transmission circuit, a magnetic head chip, a security chip and a main control equipment interface connected with external card swiping main control equipment; the information transmission circuit is used for providing information transmission channels between the security chip and the magnetic head chip, and between the security chip and the main control equipment; the magnetic head chip is used for converting magnetic stripe card information into a digital signal and sending the digital signal to the security chip; and the security chip is in wire bonding with the informationtransmission circuit in a bare chip form, and is used for receiving the magnetic stripe card information and carrying out encryption processing on the magnetic stripe card information. According to the technical scheme, a modular design thought is used; all the modules are connected through the hard PCB; the universal encrypted magnetic head module is connected with a card swiping machine througha cable; the main control equipment such as multiple card swiping machines and the like can be compatible by only changing the cable; and the cost of the whole magnetic head module is reduced while the security of user information is relatively high and the compatibility of an encrypted magnetic head is enhanced.

Description

technical field [0001] The invention belongs to the field of information security, and in particular relates to a general encrypted magnetic head module. Background technique [0002] With the development of the payment industry and the improvement of everyone's security awareness, more and more card swiping devices now need to have higher security attributes, which also requires that the magnetic head of the POS machine to swipe the card must be an encrypted magnetic head. When the original unencrypted magnetic head swipes the card, the information of the user's magnetic stripe card will be directly transmitted in the system in the form of plain text, which has great hidden dangers. For example, the encrypted magnetic head with a built-in security chip can effectively protect sensitive information from leakage. [0003] The encryption head with a built-in security chip has a large increase in the cost of the head due to the addition of a security chip. In the increasingly c...

Problems solved by technology

[0003] The encryption head with a built-in security chip has a large increase in the cost of the head due to the addition of a security chip. In the increasingly competitive POS machine market, this kind of high-cost head is obviously not competitive.

Moreover, there are various manufacturers and models of POS machines on the market, and the connection parts are different. It is difficult to have a general solution to make the encrypted magnetic head have high compatibility and can be integrated on different POS main control devices.
