These scans recharge at a rate of one every two hours. When the player performs a scan, one of these icons becomes darkened. This limit is indicated by a row of 10 scan icons along the top of the 3DS's upper screen. The player is limited in the number of times they can scan QR Codes in succession. Scanning any QR Code records the Pokémon it describes as seen in the Pokédex if it is not already.
The QR Scanner's main function is scanning QR Codes. Pokémon Brilliant Diamond and Shining Pearl.
