| Reverse description | The reverse is printed on white stock and consists entirely of a repeating diagonal text pattern in blue, with no pictorial vignette or guilloche element. The legend 'SIEMENS NIXDORF WORLDWIDE SELF-SERVICE SOLUTIONS' is repeated in uniform rows across the full surface, serving as a functional test pattern to simulate the microprinting or background lettering security feature used in currency authentication equipment. |

| Comments |
Siemens Nixdorf Informationssysteme AG produced test notes like this one for internal calibration of their currency-handling machines — ATMs, sorters, and validators — rather than for any monetary purpose. The notes were engineered to precise mechanical tolerances so that equipment could be tested and certified without cycling real banknotes through thousands of repetitions of wear and sensor checks.
Siemens Nixdorf itself existed only between 1990 and 1996, when Siemens AG acquired the struggling Nixdorf Computer AG and later spun off the merged entity as Wincor Nixdorf. That narrow corporate window dates this piece fairly tightly.
