Diebold was an American financial self-service, security and services corporation. A part of Diebold Nixdorf since August 2016, the entity is internationally engaged primarily in the sale, manufacture, installation and service of self-service transaction systems, electronic and physical security products, software and related services for global financial and commercial markets. Founded in 1859 in Cincinnati, Ohio as the Diebold Bahmann Safe Company, after becoming incorporated in Ohio in 1876 the company changed its name to Diebold Safe & Lock Company. Currently headquartered in the Akron-Canton area with facilities in nearby Green, in 1921 Diebold sold the worlds largest commercial bank vault to Detroit National Bank. Diebold has since branched into diverse markets, and is currently the largest provider of ATMs in the United States. With 2015 revenues of US$2.42 billion, Diebold acquired Germanys Wincor Nixdorf in 2016, integrating it to form Diebold Nixdorf. It is estimated that Diebold Nixdorf controls about 35 percent of the global ATM market.
