SECURE HOUSING CONTAINING A KEYBOARD FOR INSERTING CONFIDENTIAL DATA

摘要

The invention concerns a secure housing containing a keyboard for inserting confidential data such as a personal identification number designed in particular for a secure electronic payment system in terms of mechanics, electronics and electromagnetic emission. Said housing comprises a capacitive touch-sensitive matrix (2) connected by conducting wires (6) to a printed board (7) bearing the associated controller, a security module (16) as well as an electronics sensitive to variations of the system capacitance, and sandwiched between two glass plates, namely a front glass plate or protective plate (3) and a rear glass plate or support plate (5).
