Tamper protection device and data transaction apparatus

摘要

A data transaction apparatus includes a housing, a system circuit board comprising a tamper detection circuit disposed in the housing, and a tamper protection device configured to seal the system circuit board within the housing in a detachable manner. The tamper protection device includes a tamper resistant board and a resin layer covering the tamper resistant board, wherein the tamper resistant board includes a flexible substrate and a plurality of fence-like lead wires disposed on the flexible substrate. In one embodiment of the present disclosure, the tamper detection circuit is triggered to generate a secure response when a tamper event is detected.
