Please add a new field type for barcodes. I realise there are 30+ types of barcodes, so perhaps start with the most popular today - the QR codes - that would be massive improvement!!! Later, you could allow scanning it, and expand the range, but native support would be so much better than the clunky attachments. Pretty please!
solid +1, I use 1password both professionally and on family basis, I share membership cards of stores with both colleges and partner. can be a new fieldtype, but a 'show as barcode' in the field dropdown will do perfect as well. The scanner to import te barcode you already have in place in the 'One Time Password' field type.
Thank you for chiming in on this as well @Matthias_Autrique
