Pin Pad With Protection Shield

      Shield 1 on key pad 2 serves to protect the entry of
the personal identification number or other secret data from
unauthorized viewers.

      Protection shield 1 consists of vertical lamellae 3 subdividing
the key pad into columns 4, 5 and 6 (number keys) and 7 (function
keys).  Column 7 is wider than columns 4 to 6.  The front side of the
columns with the bevelled lamellae 3 is open, whereas the back side
is closed by a wall 8 linking lamellae 3.  Lamellae 3 and wall 8 have
the same height (about 2 to 4 cm) which is chosen such that the key
pad is reliably protected and easy to operate.

      Shield 1, which protects the entry of secret data from
unauthorized viewers, is subdivided such that all keys are readily
visible to the operator and directly accessible by him.
