It’s come to my attention that very few android/G1 phone owners know about one of my favorite features, reading and creating 2D barcodes! First, if you haven’t already done so, download the free application “barcode scanner” from the android market. Now that you have the app, select “menu” => “share” and you can create a 2D barcode of any of your contacts as well as bookmarks. If one of your buddies has a 2D barcode reader on his or her phone they can simply scan the code you just created! Once they’ve scanned the 2D barcode they will be prompted to launch their browser and/or save the contact info. If you want to create a 2D barcode and share it via your website like we’ve done here and here there are several free and easy sites you can use. Here are couple of my favorites: zxing and nokia barcode generator FYI, there are several types of 2D barcodes but the G1/barcode scanner only supports “QR”.
