A general encryption head module

Abstract

The application discloses a general encrypted magnetic head module, which includes a hard circuit board, and the hard circuit board is provided with: an information transmission circuit, a magnetic head chip, a security chip, and a main control device interface for connecting an external card swiping main control device, The information transmission circuit is used to provide an information transmission channel between the security chip, the magnetic head chip and the main control device; the magnetic head chip is used to convert the magnetic stripe card information into a digital signal and send it to the security chip; the security chip is bare The chip form is wire-bonded with the information transmission circuit, and is used for receiving the information of the magnetic stripe card and encrypting the information of the magnetic stripe card. The above technical solution uses modular design thinking, uses hard PCB boards to realize the connection of each module, and connects to the card reader through a cable. Only changing the cable can be compatible with a variety of card readers and other main control devices, ensuring the security of user information. Higher and enhanced encryption head compatibility while reducing the cost of the entire head module.

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.
