In terms of security protection, existing metal encryption keyboards mainly protect data through metal box devices and flexible FPC circuit structures. Not enough, it cannot effectively protect the data in the metal encryption keyboard in a timely and effective manner. After tearing off the flexible button layer on the PCB circuit board, when stealing the data in the metal encryption keyboard, it is easy to avoid the self-destruct device. trigger device, so that the effective protection of the data in the metal encrypted keyboard cannot be achieved

The invention relates to a metal encryption keyboard and a production method thereof. A releasable printed conductor is adopted to design a safe loop in the metal encryption keyboard, and the safe loop is used for triggering a self-destruction device to achieve protection for data in the metal encryption keyboard. The metal encryption keyboard is simple in designed structure and can overcome defects of the existing products and achieve a good safety protection effect. By adopting the production method of the metal encryption keyboard, the metal encryption keyboard is easy to produce and convenient to popularize in the market.
Description
technical field [0001] The invention relates to a metal encrypted keyboard and a manufacturing method thereof. Background technique [0002] Metal encryption keyboard is a type of metal keyboard. It has all the characteristics of metal keyboards and also has encryption functions. Therefore, in the field of financial data security protection, metal encryption keyboards are widely used in ATM machines, POS machines, and self-service payment. system and a series of input devices that require password security. [0003] Because it involves property security, the metal encryption keyboard needs to have high data security, and some specific devices and measures are required to ensure data reliability and security during the operation of the equipment. In terms of security protection, existing metal encryption keyboards mainly protect data through metal box devices and flexible FPC circuit structures. Not enough, it cannot effectively protect the data in the metal encryption keyb...
