| Zusammenfassung: | A PIN entry terminal comprises an interface board, tamper resistant boards and a main board. The tamper resistant boards tightly enclose the main board. There is a plurality of solder joints between each adjacent two of the tamper resistant boards and the main board. Furthermore, an electrical connector electrically connects and is placed between the interface board and the main board. A tamper detection circuit through the solder joints and the electrical connector is provided in part on the tamper resistant boards, in part on the interface board and in part on the main board. If the interface board or the main board is disconnected from the electrical connector or one of the tamper resistant boards is tampered with, the tamper detection circuit is triggered. |
