[0018] like Figure 1 As shown, an anti-probing structure for a POS terminal includes a POS terminal and a circuit board assembly 1 arranged in the POS terminal, characterized in that: a chip 2 electrically connected to the circuit board assembly 1 and an anti-probing cover 3 covering the chip 2, and the anti-probing cover 3 is electrically connected to the chip 2.
[0019] Working principle: Since the chip 2 is provided with an anti-stab mechanism, when the anti-stab cover 3 is removed or pried to a certain distance, the loop formed between the anti-stab cover 3 and the chip 2 is destroyed, which can trigger the anti-stab mechanism in the chip 2 to erase the financial transaction information and related information interaction data, thereby avoiding the leakage of the financial transaction information and related information interaction data in the chip 2; the utility model can effectively prevent the financial transaction information and related information interaction data on the POS chip 2 from being pried by the prying probe, and is safer and more reliable to use.
[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the anti-probe cover 3 includes a metal shell 31, an FPC 32 arranged on the inner side of the metal shell 31, a plastic bracket 33 arranged on the inner side of the FPC 32, and a zebra stripe 34 arranged on the inner side of the plastic bracket 33.
