We advise using unique non sequential alphanumeric (letters / numbers) when creating your own barcode data. 

Qflow for events will auto generate the barcode code image based on this data. 

Please note - You can upload your guest data without barcode data and by selecting the Add barcode option during the invite creation process Qflow for events will automatically create and add unique-to-guest barcodes on your guest invites.

IMPORTANT - PLEASE DO NOT ADD SPACES IN YOUR BARCODE DATA. THIS WILL RESULT IN UNSUCCESSFUL SCANS AS SPACES ARE NOT COMPATIBLE WITH BARCODE DATA.
