摘要： The illustrative embodiments described herein provide an apparatus and method for detecting tampering. The apparatus includes a printer and a printer compartment located within the printer. The apparatus also includes a switch capable of being coupled to the printer compartment. The switch is adapted to close when tampering with the printer compartment occurs. The apparatus includes a tamper detection device capable of being in a tamper state and a non-tamper state. The tamper detection device discharges and places the tamper detection device in the tamper state when the switch is closed to indicate that tampering has occurred. The apparatus includes a set of power sources. The set of power sources provides charge to the tamper detection device and places the tamper detection device in the non-tamper state.

摘要： A computer implemented method and data processing system for providing a hardware controlled one-time write for fiscal printers. A signal from a fiscal printer is received at a memory controller in an electronic journal or fiscal memory card. The signal comprises transaction data and an address in a memory space in the electronic journal or fiscal memory card. The memory controller checks a marker bit corresponding to the address to determine if the marker bit is in a written state. Responsive to a determination that the marker bit is not in a written state, the memory controller sets the marker bit to the written state. The memory controller then writes the transaction data to the address in the memory space.
