Abstract: A shield for overlying a keypad such as a PIN pad. The shield 10 permits manual access to the pad 24 and comprised a screen 30 having a transverse direction and a longitudinal direction and formed from a transparent material through which in use the keypad is viewable by a user of the keypad only from within a limited angular range. The screen has an upper side 44 directed in use generally toward a user and a lower side 41 directed in use generally toward the keypad, the screen further having an upper series of transversely extending parallel opaque strips 45 and transparent gaps, and a similar lower series of strips 40 and gaps, which lower series is offset from the upper series so that, when viewed from above, the opaque strips of the upper and lower series overlap and block the view.
