Hi atumuser ,
Sorry for the late response. I needed to check some questions with the dev team.
Neither ATUM nor its plugins have a picking-up functionality, sorry.
We're working on a new add-on ATUM Barcodes Pro. It will allow you to enter and generate Orders QRs. However, I can't figure out how that could be used to confirm the pickup.
Best Regards,
José Andrés
