Productivity blog Lifehacker links to a great service by Boxmeup, a website that allows you to create virtual containers that you can use to track stuff in boxes and other bulk storage systems. It uses for labels QR codes, bar codes that can be scanned by most smartphones today.
The service is really useful for pack rats like me who can’t seem to let go of things, even 5-year-old notebooks and ancient press releases.
With Boxmeup, you can list the things you place into a container and then generate a QR code that you can use as label for the box. The next time you are looking for something—interview notebooks for a libel case, heavens forbid—you can just use your phone to scan the QR codes of your boxes and containers and you’d know right away what are stored inside these.
