7.4 AQtap safety concept

AQtap water dispensers are provided with a number of safety
measures to avoid misuse by invalid smart cards or keys:
• Each AQtap is delivered with a pair of unique keys for the
cabinet. Spare keys cannot be purchased. We recommend to
keep one key as a master for copies in a safe place.
• The AQtap owner receives three smart cards that are
preassigned to the proprietary WMS group: two AdminCards
and one ServiceCard.
• All further smart cards must be ordered separately and
activated at the AQtap.
• Smart cards can be used at all AQtaps within their group.
Smart cards assigned to a group cannot be used within
another group.
• AdminCards and ServiceCards are code-protected. The code
must be set at the AQtap when the cards are used for the first
time. The set code cannot be changed afterwards.
• All smart cards can be blocked permanently via WMS.

7.5 Overview of components and connections

The AQtap components are connected through different
communication technologies making it possible to exchange data
between the involved components.
All transactions between smart cards are carried out directly at
the AQtap.
