KarL4 is our innovation for contactless payment for the girocard, MasterCard and Visa Card. The payment terminal runs entirely without a PIN pad (TOPP) and allows quick age verification on request. This enables your customers to pay securely and intuitively with girocard contactless amounts up to 50 Euros without entering a PIN. KarL4 uses Near Field Communication (NFC) for data transmission. This ensures extremely customer-friendly handling: pull out your card, put it on and pay.

KarL4 can optionally be combined with our Human Machine Interfaces, if desired even as a highly individual complete module tailored to your requirements. Quality "Made in Germany", approved by the German Banking Industry (DK). Profit from our many years of experience in the development and manufacture of more than 100,000 card payment systems.

In the future, SECO also plans DC-POS 3.0 certification, which will additionally enable acceptance of American Express (AMEX), Discover, Union Pay, and JCB.
