This validator for electronic and paper tickets is equipped with a touch monitor, which displays information about transactions, the content of the card and its validity period. Optical signalling devices are placed over the monitor. They inform about operations completed correctly. An electronic ticket is validated by placing the card close to the active area at the bottom part of the device. The validator meets the contactless card standard – ISO 14443 A, B. Ticket validation is carried out automatically after inserting the ticket into a special slit. The validator is used in the systems of the Electronic Urban Card and paper tickets.
