Another reason to request it is to get around the fact that iPhones don't have NFC. If there was an alternative way to produce bar codes, say with a partnering start-up like sticky bits, then have those location reminders (barcodes stuck in convenient places) open up relevant notes, task lists, etc, the bar code integration would be very handy. I'm especially suprised in the task management world how few tools are meant to integrate with one's chosen habits. Routines and tasks, sure. But if you have trigger objects throughout your day, people would make a habit of using Evernote to enhance their activities, even for the subconscious actions.
