A coin processing device (10) and a method for classifying coins are provided. The coin processing device (10) includes at least one computerized controller (9) having a storage unit (36), and at least one coin channel (34) for guiding a coin (35). The at least one coin channel (34) includes at least one sensor (37) suitable for measuring a passage time of the coin (35). An accelerating device (43) is connected to the computerized controller (9) and is designed to accelerate the coin (35) in a reproducible manner. A target speed value for a specified coin (35) is stored in the storage unit (36). An actual speed value is calculated based on the transport time detected by the sensor (37). A coin class of the coin (35) is ascertained by the computerized controller (9) from the comparison of the target speed value and the actual speed value.

Currency inspection using mobile devices and attachments are provided herein, as well as methods of use. In some embodiments, an apparatus may be configured to provide selections of currencies to a user via a display of the apparatus, obtain currency attributes for a selected currency, receive currency parameters for suspect currency using a currency evaluation device that is communicatively coupled with the apparatus, the currency evaluation device having a sensor array that comprises one or more sensors that are each configured to determine at least one currency parameter, compare the currency parameters for the suspect currency to the currency attributes, and output a warning message if the suspect currency is potentially counterfeit.
