Abstract
An apparatus, system, and method are disclosed for detecting tampering of devices such as fiscal printers. A memory module includes a volatile memory that stores multi-bit data. An operation module allows operation of an electronic device, such as a fiscal printer, in response to determining that the predefined multi-bit data is stored in the volatile memory. A detection module detects an attempt to access the enclosed device where access to the enclosed device is restricted by an enclosure. A tamper switch module disconnects power to the volatile memory such that the predefined multi-bit data stored in the volatile memory is erased in response to the detection module detecting an attempted access to the enclosed device. A shutdown module disables operation of the electronic device in response to determining that the predefined multi-bit data is not stored in the volatile memory.
