The Office of Learning Technologies is currently working on an application based on QR codes (Quick Response Codes),  two dimensional codes designed for storing information in small spaces.  The UOC QR Codes aims at mobile device users since they  would allow to easily access to UOC addresses and URLs from a mobile or a PDA .
The increasing aplicability of QR Codes has not only been noticed by UOC. Moodle, for instance, has just released an enhancement for Moodle users who want to access material on their mobile device. Moodle pages have long, crufty URLs that would be difficult to enter into a mobile browser. To help these users, QR codes are automatically added to Moodle pages.
