Tag My Doc lets you put a "tag" (QR code) on any document which can be scanned with a mobile device and retrieved as a virtual copy of the document. Tag My Doc is like reverse printing…instead of going from virtual to paper your document goes from paper to virtual. Tag My Doc lets you share documents any time.
QR Voice is a free tool that allows you to create QR codes that when scanned will play a short audio message. To create your message and QR code you can record a voice message by clicking the microphone icon on QR Voice or you can type in your message. Either way you're limited to 100 characters. QR Voice is offered in Spanish, English, Japanese, and Portuguese.
