We'd love to see this too. Actually, we'd love to see just a new panel in the admin that when a bar code is scanned, it pulls up the users record and marks them as attended and then pops open a name tag proof window with a print button. Scan, preview, print, done.
Yes, I would love this! I really need a way to easily scan tickets at the door otherwise the barcodes are pointless. Any ideas on when this will be ready?
