Modular characteristic for surfaces of self-operating systems

摘要

The self service device has a housing (1) in which a data-entry device is provided, and a card reader (2) for smart cards (8). The housing or the data-entry device is provided with additional elements or additional particulates that are fluorescent and phosphorescent. The additional elements or additional particulates are distinguishable only in the infrared wavelength range of electromagnetic spectrum of the particles surrounding them.
