The instructions allow the owner of a Nayax Cashless Payment System to register Rfid ValuCards that have a 16 digit serial number. The initial step is to contact Nayax with the serial number of the Nayax Cashless Payment System to log on to the Nayax server with a password. The Nayax must be connected to a power source and be in operation to communicate with the host Nayax server. Once this dashboard is loaded on your PC, then you can go to the menu and located the Nayax serial number. For more information, contact Nayax directly for "Customer Support".
