Diebold Nixdorf is an American multinational financial and retail technology company[4] that specializes in the sale, manufacture, installation and service of self-service transaction systems (such as ATMs and currency processing systems), point-of-sale terminals, physical security products, and software and related services for global financial, retail, and commercial markets.

[5] Currently Diebold Nixdorf is headquartered in the Akron-Canton area[6][7] with a presence in around 130 countries, and the company employs approximately 23,000 people.

[14] On June 1, 2023, Diebold Nixdorf filed for Chapter 11 bankruptcy, saying it reached an agreement to restructure and reduce its debt by $2.1 billion.

[10] Under the leadership of founder Charles Diebold, a German immigrant,[17] the company's 250 initial employees[18] began manufacturing safes and bank vaults[17] out of a factory in Canton, Ohio.

[10] In 1874, Diebold was contracted to build the world's largest safe, to be installed in the San Francisco branch[19] of Wells Fargo.

[10] In 1965 Diebold began offering pneumatic tube delivery systems to diverse institutions including banks and post offices.

[20] This drive was evident as early as 1966, when Richard Glyer demonstrated a Diebold cash machine prototype at the annual meeting of the American Bankers Association in San Francisco, CA.

[21] Then in July 1970, Daniel Maggin, chairman of the board, accompanied Koontz to England with the specific purpose of meeting (without prior notice) with Chubb’s Managing Director, William E. Randall.

Not surprisingly Diebold finally stopped distributing Chubb devices in 1973 and at the same time, decided to develop and eventually launch its own Total Automatic Banking System (TABS) 500.

[25] Diebold partnered with IBM on InterBold in 1990, a joint venture chiefly formed to provide self-service products for the financial industry.

[29] In October 1999, Diebold acquired all the stock of Procomp Amazonia Industria Electronica, S.A, a manufacturer of retail and banking automation equipment such as ATMs based in Sao Paulo, Brazil.

[27] In 2001, Diebold acquired Mosler Safe Company in bankruptcy court and took over their operations, including securing the Charters of Freedom (the US Constitution, Bill of Rights, and Declaration of Independence) for the US National Archives in Washington, D.C.[30][10] In February 2002, Diebold announced it would acquire the financial self-service assets of the European companies Getronics NV and Groupe Bull for approximately US$160 million.

[28][35] DES was soon the subject of controversy amid allegations surrounding the security and reliability of some of its products,[36] as well as the political fundraising activities of Diebold's then-CEO Walden O'Dell in 2003.

[38] Citing personal reasons,[39] O'Dell resigned in December 2005[40] after several consecutive quarters of poor performance,[39] with his role taken by Tom Swidarski.

[10] In March 2008, United Technologies Corporation (UTC), a large engineering and defense conglomerate, announced it had made a $2.63 billion bid to buy Diebold, which was later rejected as too low.

[10] After a lawsuit brought by the SEC alleging deceptive accounting between 2002 and 2007, several Diebold executives paid settlements in June 2010 to have the charges dropped, without admitting any liability.

The company debuted a prototype of the first virtualized ATM that year, which was created jointly with VMware and used cloud technology.

[41] On October 25, 2012, the company announced it was suspending plans to build a new world headquarters in Green, Ohio, saying it was no longer economically feasible.

[49] CEO and President Thomas Swidarski resigned in January 2013 after pressure from the board over poor financial performance.

The Justice Department agreed to drop the charges if Diebold complied with various terms, including 18 months of compliance monitoring and a $48 million settlement.

"[52] In July 2014, Diebold introduced its ActivEdge card reader, which it claims "prevents all known forms of skimming [ATM crime].

[61] Software development for the new company would take place in North America, with Diebold citing their Phoenix Interactive Design subdivision based in Ontario, Canada.

The company was re-focused exclusively on its current product set in 1998 and renamed Siemens Nixdorf Retail and Banking Systems GmbH.

Following a buyout by Kohlberg Kravis Roberts and Goldman Sachs Capital Partners on October 1, 1999, the company was renamed Wincor Nixdorf.

Diebold Nixdorf markets its products and services in diverse industries, including the financial, commercial, and retail spheres.

[11] Diebold has developed a number of physical and electronic security products,[63] and in recent years has been contracted to protect the World Trade Center Transportation Hub,[10] the Hope Diamond at the Smithsonian Institution,[28] and the United States Constitution, among other notable artifacts and landmarks.

[10][28] Diebold also introduced the first talking ATM in the United States that year, which was installed on October 1, 1999, in San Francisco's City Hall.

[58] The first model Irving, which was undergoing testing by Citigroup at the time, allows customers to withdraw money with an iris scan, removing the need for a card.
