Reliable POS Keyboard with Integrated Card Readers

Reliable POS Keyboard with Integrated Card Readers

The Challenge

Hellenic Duty Free Shops S.A (HDFS) is dedicated to offering to all travelers passing through the exit controls of Greece the ultimate shopping experience. It operates 114 stores at 46 locations (airports, border and ports) across the country. HDFS was looking for a compact and highly reliable data input device for the POS terminals at their duty-free shops in all airports, border stations and seaports across Greece. 

The goal was to acquire a premium POS keyboard that runs 24/7 without any problems. Particularly important was the option to integrate different modules so the cashiers would be able to read magnetic cards as well as smartcards with just one compact device. Besides a small footprint HDFS required an alphanumeric layout that also fitted a number pad.


The Solution

Our compact POS keyboard MCI 96 matched all requirements perfectly. Due to its high quality the programmable keyboard has a long service life at very low failure rates. With its compact measurements the keyboard offers the perfect size and integrates an alphanumeric layout with number pad and two integrated card readers in a one cable solution at the same time. With the individually laser etched logo, the programmed keyboard integrates seamlessly into the appearance of the duty free shops.

With the assistance of PrehKeyTec long term business partner N. Asteriadis S.A. the acquisition and integration of the keyboard into the POS systems was smooth and easy. 

“We have been using programmable keyboards from PrehKeyTec for many years to save time at our checkouts. The reliable human machine interface helps us to serve customers in our duty-free shops efficiently and without any delays.”
