A sensitive element protection mechanism and a payment device using the sensitive element protection mechanism includes a circuit board; a sensitive element configured for storing, transmitting and/or processing user account information and user transaction information; a shield arranged in parallel with the circuit board; and an elastic member connecting the circuit board and the shield. The sensitive element is located on a side of the circuit board near the shield. The circuit board and the shield are provided and the sensitive element is provided between the circuit board and the shield so as to protect the sensitive element through the shield. The elastic member connects the circuit board and the shield to prevent the circuit board from being separated from the shield, thus preventing the circuit board from being opened to steal sensitive information in the sensitive element.

Sensitive element protection mechanism and payment device

A hardware encryption housing and a payment device using the hardware encryption housing includes a top shell, a bottom shell, a circuit board and a trigger switch configured to transmit a trigger signal when the top shell is separated from the bottom shell. A security chip, mounted on the circuit board, has a storage module configured to store key information and a detection module configured to clear the key information and lock the security chip after the trigger signal is detected. The trigger signal is transmitted when the top shell is separated from the bottom shell, and the detection module is provided in the security chip to detect whether the trigger switch transmits a trigger signal. When detected, the key information in the storage module is cleared and the security chip is locked.
