When moving or just organising, QR codes are great to quickly find what items are in your boxes. Boxmeup takes this up a level by combining their QR generator with an online list of the items in your boxes. You can even search your account on the site and find out what box you left your snorkelling gear in.
Sure we've covered making QR labels before, but Boxmeup adds enough punch to consider using it even if you already QR code your storage boxes.
Boxmeup is a free web app for all platforms.
