TagMyDoc is a service that allows you to automatically add a QR code to your document as it is stored in the cloud. Your recipients receive the virtual copy by accessing it from the QR code and they are able to print your document any where any time. TagMyDoc lets you say good bye to email when you're sharing documents.
TagMyDoc offers 1 gigabyte of storage for free. Any type of document can be tagged except images (jpg, png, bmp, gif, tiff and tif extensions).
You can download add-ins from the TagMyDoc site so that you can use the service directly from within Word and PowerPoint. Easy!
TagMyDoc - Not only is it cool, it's efficient, green, and accessible - and as their website states: genius!
