You probably won't even need to go to shops to scan the extra characters in. I'm sure you can do it off online photos. Someone might even compile a barcode gallery. Codes aren't super necessary, the in game store can unlock them for you by cashing in energon cubes earned in game.
But extra characters aren't the only reason for the codes. There are supposed to be new codes appearing on Transformers.com regularly.
