I was notified of a cool new beta today called TagMyDoc, which enables you to embed QR codes directly into Microsoft Office documents. This allows you to share documents with anyone who can scan a QR code. The majority of people can do this already using their mobile device.
So, what happens?
Using a special add-in, you create a QR code for you document and the document is uploaded to the TagMyDoc web site. When someone scans the QR code for your document, the document is automatically downloaded to their device.
TagMyDoc is both a web site/service and a downloadable component for Microsoft Word, Excel, and PowerPoint. For now, the downloadables only support Windows and Microsoft Office products. If you use an alternate Office package, the web site will allow you to attach a QR code to your alternate format documents.
A free account is required and is limited to 100 documents, 2MB of max document size, and 3 versions of each document. However, it offers an unlimited number of followers (sharers). If you need more than the free service offers, TagMyDoc has both a Premium and Premium Plus service for nominal fees per month.
