Hi eslamx7
The barcode feature is integrated in our ATUM APP, which is in beta testing just for premium users.
So please, if you are interested in testing the ATUM APP, I have to ask you to open a private ticket with your license, and also we need to know if you are an Android or an iOS user.
This is the link to open a private ticket: https://stockmanagementlabs.ticksy.com/
Best Regards,
Andrea.
