Installing the NFC antenna
The NFC antenna is suitable for installation behind a glass front as well as for mounting on the

of the screws depends on the wall thickness of the vending machine door. The screws must not

A length of 8 mm should generally suffice.
The fixing screws are not included in the scope of delivery of the NFC antenna.
Appropriate holes (4x 5.5 mm and 1x 25 mm) must be drilled in the vending machine door for
the fastening screws and for the cable feed-through. Two drilling templates are available to
make this easier:

antenna itself and can therefore always be used,
especially where only limited space is available for
mounting the antenna.
