Hi maydel ,
We're working on releasing the mobile APP in the next weeks.
Regarding your question about the scanner, the app includes that functionality. We don't plan to add support for external scanners connected to your mobile device. I'm sorry.
However, if your scanner is connected to your computer, you can already use it (Barcode scanners work as text input devices) to fill the barcode fields or search by them.
Best Regards,
José Andrés
