Diebold Nixdorf: the history behind its technology business

Diebold Nixdorf combines two long technology lineages. Diebold traces its roots to an American safe-and-lock business founded in 1859, while Heinz Nixdorf established a computing laboratory in Germany in 1952 that ultimately became part of Wincor Nixdorf.

How Diebold Nixdorf developed

Diebold completed its acquisition of Wincor Nixdorf in August 2016 and the combined business adopted the Diebold Nixdorf identity, bringing together ATM, retail self-service, software and service operations.

Diebold Nixdorf in 2026

By 2026, Diebold Nixdorf supplied cash-management, self-service banking, retail checkout, software and managed services to financial institutions and retailers.

Why the history matters

Its history is a story of repeated reinvention: physical security, computing, ATMs and retail automation all became connected through the need to manage trusted transactions in public locations.
