KarL4 is a contactless-only reader (COR) payment terminal. It enables your customers to quickly and securely make payments for amounts up to EUR 50 with a debit or credit card without having to enter a PIN. KarL4 uses Near Field Communication (NFC) to transfer data. This simplifies the payment process for customers: simply pull out the card, position it and pay. 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.
