+For outdoor games, scanning the code and answering questions will make the pin disappear from the map. It is considered answered.

You can make pins for questions meant to be activated by EAN code transparent and put the pins away from the main game area. Give hints what product code to scan in questions after answer comments or chat.

More obvious way is to make the pin visible and set a radius to 0m in the game’s locations screen. In the question’s intro describe what the players have to scan to open up this task. “Find a candy bar “Delicous bite” from this cafe and scan its barcode. Use the scanner in the game side menu!
