If the first shell 1 is disassembled, in the process of being disassembled, as long as any one of the anti-disassembling pieces 41 is separated from the copper leakage area 31, the monitoring chip 5 will detect an anti-disassembling signal (at this time, an anti-disassembling PIN signal is a high level signal), the monitoring chip 5 will lock the equipment, and all sensitive information will be deleted.

After triggering the anti-disassembly function, the whole machine is powered on again, the control mainboard 3 can read the disassembly state information of the monitoring chip 5, the prompt information such as 'equipment anti-disassembly triggered' can be popped out on the display screen 9, voice prompt tones, indicator light twinkling and the like are generated, and the whole machine operating system is locked and cannot operate normally.

The control mainboard 3 prevents tearing open the state discernment and can have two kinds of modes:

(1) GPIO port state identification:

when the payment equipment does not normally trigger the anti-dismounting function, the anti-dismounting state GPIO of the monitoring chip 5 outputs an L signal to the control mainboard 3;

when the payment equipment triggers the anti-dismounting function, the anti-dismounting state GPIO of the monitoring chip 5 outputs an H signal to the control mainboard 3;

when the payment device is connected with the adapter 63, the control mainboard 3 is powered on, the level of the anti-disassembly state GPIO of the monitoring chip 5 is scanned firstly, if the level is 'L', the operation system is normally entered, and if the level is 'H', the corresponding protection process is executed.

(2) Serial port communication:

after the payment device is connected with the adapter 63, the control mainboard 3 is powered on, the state of the monitoring chip 5 is read through serial port communication, if the normal state is received, the operation system is normally entered, and if the trigger state is received, the corresponding protection process is executed.

To sum up, the utility model provides a payment equipment forms installation space at its first casing 1 and 2 fixed connection of second casing, install control mainboard 3 in the installation space, prevent tearing open module 4 and monitoring chip 5, monitoring chip 5 respectively with control mainboard 3, prevent tearing open module 4 electricity and be connected, when first casing 1 separates with second casing 2, prevent tearing open module 4 and send the dismantlement signal, monitoring chip 5 monitors to lock control mainboard 3 behind the dismantlement signal, in order to prevent that control mainboard 3's data information from being stolen, effective protection payment equipment's consumer information, improve payment equipment's security and reliability. Prevent tearing open module 4 including preventing tearing open piece 41, prevent tearing open the one end and the first casing 1 fixed connection of piece 41, prevent tearing open the other end of piece 41 and the hourglass copper district 31 butt on the control mainboard 3, prevent tearing open piece 41 simple structure, easy installation is favorable to reducing payment equipment's cost.
