KarL4 receiver

Contactless payment made simple with KarL4

KarL4 – the new contactless payment system by Garz & Fricke is quick and easy to integrate. It enables your customers to make payments for amounts up to EUR 50 in a secure and straightforward way from their girocard debit card without having to enter a PIN.

KarL4 can be optionally combined with our touch display HMIs and, on request, can even be tailored to your requirements as a highly individual complete module.
