| Obverse lettering | SIEMENS NIXDORF 50 MUSTERBANKNOTE TEST NOTE SPÉCIMEN Siemens Nixdorf Informationssysteme AG U23539-J-Z751-1 |
| Reverse description | The reverse presents an all-over diagonal underprint pattern composed of repeating text in alternating gold and steel-blue ink, with the phrases "SIEMENS NIXDORF WORLDWIDE", "SELF-SERVICE SOLUTIONS" and "SIEMENS" arranged in parallel diagonal bands across the entire surface. No central vignette or figurative element is present; the design functions purely as a security-style background fill intended to simulate the optical properties of genuine currency for ATM sensor calibration. The overall effect closely resembles the guilloche-type multicoloured underprint found on circulating banknotes. |

| Comments |
Siemens Nixdorf Informationssysteme AG produced these test notes in-house to calibrate and validate their banknote processing and sorting machinery — the ATM and cash-handling equipment market the company competed in aggressively through the 1990s. The notes were never intended for any monetary system; they exist solely as mechanical feed stock, designed to replicate the physical behavior of genuine currency under high-speed automated handling.
Siemens Nixdorf itself was a short-lived entity, formed from the 1990 merger of Siemens Data Systems and Nixdorf Computer AG, and dissolved into Wincor Nixdorf in 1999. That narrow window brackets the production of these notes precisely.
