# Limitation of Scanning the Same Barcode

**The same barcode can be scanned only one time during the same season.**

* Barcode scanning is limited to once per season for all players. If the new season begins, the same barcode can be scanned once more.
* If the error message appears (<img src="/files/IWwwhle8lqStadP8ZPO0" alt="" data-size="line">), someone else has already scanned the barcode.

*note: Please refer to* [Story / Season / Battle](/what-is-scannner/story-season-battle.md) *to learn about the season.*
