Abstract:
1. An analytical system including an analytical disposable, comprising at least one test unit and an information carrier which comprises a two-dimensional code formed by graphic symbols configured for machine-readable provision of test-specific information, and an optical reading device for the two-dimensional code that includes a sensor defining a detection area, wherein the code comprises a base code area containing the information and a generally adjacent copy code area containing a copy of at least a section of the base code area, wherein the copy code area adjoins an edge of the base code area, and the dimensions of the two-dimensional code defined by the copy code area and the base code area are greater than the detection area of the sensor of the optical reading device so that the detection area of the sensor does not extend beyond the edges of the code defined by the base code area and the adjoining copy code area, wherein the two-dimensional code is applied to a transparent or translucent substrate and is readable under transillumination as a shadow image projected onto a flat sensor.
