# 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="https://3679207111-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fo2TtFThqrwWIkv8NRSem%2Fuploads%2F0oYCQLYJw8SHSf1OUnjm%2Fnum_1.png?alt=media&amp;token=35ac756f-e407-45a3-a5d7-61a62c309122" 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.*
