Wincor Nixdorf was a premier global provider of IT solutions, hardware, software, and services tailored for retail banks and the retail industry.
Headquartered in Paderborn, Germany, the company historically commanded roughly 35% of the global automated teller machine (ATM) market and stood as a dominant force in electronic point-of-sale (EPOS) systems.
Its operations focused deeply on business process optimisation, automated cash handling, and retail self-checkout systems. In 2016, Wincor Nixdorf merged with its US rival Diebold, Inc., creating the modern consolidated market leader, Diebold Nixdorf.
