4.2 Privacy Shield
The integrator ensures that the installation situation meets the requirements for the privacy shield for the PIN
pad. Essential requirements for the installation situation are illustrated below.
To prevent spying out the PIN entry and adequate privacy protection has to be provided by the vending
machine. The horizontal observation range which has to be covered by the privacy shield is 270°. At any
horizontal angle between 315° and 45°, the card holder obscures an observer's view of the PIN pad with his
body (a symmetrical design must meet the minimum requirements at each point).
The cVEND PIN Security Guidance includes more details on how the privacy shield has to be designed.
The angles in the figures below are defined as follows:
α =
Angle bet
ween the vertical plane through the “5” key and a virtual line which connects the “5” key
and an observer’s eye.
β =
Horizontal position of an observer relative to the pin pad’s position.
γ =
Horizontal range which has to be covered by the privacy shield.
