Hi dco
Thanks for your suggestion, but as we are going to implement our own barcode system in ATUM (the ATUM App already has support for barcode scanning and handling). We don't plan to add this kind of 3rd party barcodes support to ATUM.
So, if you really need to add support for your own barcode attribute, I'd suggest you find a developer to assist you with such integration.
Best Regards,
Salva.
