2 KARL4 VENDING MACHINE MODULE
The KarL4 vending machine module is a robust, vandalism-resistant contactless payment
terminal for indoor and outdoor vending machines.
KarL4 is designed as an OEM solution. The module can be installed in existing vending
machines as well as in new vending machines and thus represents a cost-effective expansion.
KarL4 is our innovation for contactless payment with the girocard and credit card. The payment
terminal runs entirely without a PIN pad (TOPP) and allows also quick age verification if desired.
It enables your customers to use their girocards and credit cards for contactless payment of
amounts of up to €50 without entering a PIN, securely and intuitively. KarL4 uses Near Field
Communication (NFC) for data transmission.
All common smartcards according to ISO 14443 A&B,m as well as NFC are supported.
Currently, the girocard and credit card application can be used.
The electronics are housed in a robust casing that can be installed on a suitable holder using the
snap-on method. The necessary NFC antenna is mounted separately from the electronics on the
front of the vending machine.
KarL4 can be connected via MDB to the vending machine controller. Compatibility with KarL²
and KarL
is ensured.

USB is optional also possible for the connection to the vending machine controller, but not
