This add-on for the mozilla calendar project ("lightning") displays QR codes for events in the tooltips, which can be scanned and imported by a barcode scanner on your smartphone. Only essential data which can be imported by popular barcode scanners is used for QR code generation, the rest is stripped so that the event data fits within the QR code limits. Instead of utilizing a third-party web service and in this way risking the exposure of private data, the javascript qrcode library by Kazuhiko Arase is used (with some modifications).
Note: Not all available barcode scanners support the iCalendar standard correctly. If you experience troubles with time or date etc. not shown correctly, please try another scanner. This extension was tested on a Samsung Galaxy S2 using "barcode scanner" from http://code.google.com/p/zxing, and it was able to scan and recognize codes up to QR code version 30.
