The game guest data (surname, first name, date of birth) are entered manually in the app by the staff. The player blocking comparison is then carried out. However, the second option offered by this app is even faster and safer: The game guest data is scanned using the MRZ code of the player ID. The app checks the youth protection and blocking comparison and shows the result clearly using a traffic light. In the ideal case, the PIN code generation for one of the linked gaming devices is triggered and the PIN code is passed on to the game guest. After a successful check of the gaming guest, other activation solutions from adp can of course also be used, such as the device-specific card in connection with the card safe or the display on the PIN display via radio remote control.
