The value of the self-service terminal is that it can a long time to work offline, i.e. without the participation of staff. The reliability and efficiency of its operation depend on how well the components are selected and the inner space of the terminal is carefully designed, as well as the convenience of using the device. Improper design of the internal space of the payment terminal or kiosk touch immediately detects during operation. Its symptoms: difficult access to the internal components of the terminal, the inconvenience of replacing the collection and receipt tape. The use in the payment terminal of cheap components of a little-known manufacturer increases the owner’s expenses for maintenance, since it forces him to visit terminals for repair, replacement of components, troubleshooting their work more often.
