Lately I've been obsesses with QR codes. One way I've been finding them extremely useful relates to Evernote. Evernote has a feature alled an internal link. This is a URL that links to a specific Evernote record, but ONLY for a user logged into the corresponding account. To anyone else it just takes them to a login page. There's nothing personally identifiable in the URL, just a long random alphanumeric.
I've taken to making this URL into a QR code and printing them as a label to stick on various items. For example, I have an Evernote checklist of all the tools that go in a particular toolbox. Rather than print it out and keep it in the toolbox I just put a QR code on it. Scan it with my phone when I'm packing that toolbox and in under a second I'm looking at my latest version of my checklist.
It occurs to me that this would be extremely useful for 1Password as it relates to any physical object. A QR code on my deadbolt could link to my 1Password record of my currently stored lock codes. A QR code on my router could open my router credentials. A QR code on my garage door keypad could open the record with my garage codes.
I can tell you from experience with Evernote that being able to reliably access the note in a second rather than having to look it up with the search function each time makes it vastly easier. And security-wise it wouldn't mean anything to anyone else who scans it.
Happy to answer any questions I can about how it works in Evernote. Hope other people find the idea of interest!
