Hello, I am the developer of QRBeam, an app that allows to transfer data from a Mac to any smartphone via QR codes. QRBeam includes its own library to generate QR codes so you don’t need to be connected to internet to use it. With QRBeam you can: Send web links, notes or any kind of text up to 800 characters. Just drag a contact from your Address book to create its QR code Save QR codes as BMP, GIF, JPG, PNG or TIFF Use foreign characters: accentuated, Japanese, Chinese, … Don’t have a QR code reader on your smartphone? No Problem! There are a lot of them available for free for iOS, Android, BlackBerry or Symbian. This app has just been released on the Mac App Store. More information are available on my company's website: Information Appliances Promo codes are (hopefully) still available in the following thread.
