Project: Grafora Business Card
Each person gets QR code which enters contact info (full name, phone, email, url) into a smartphone.
The QR code is deliberately on the right side since most people are right-handed and tend to use a smartphone and snap photos with right hand.
Reading out or copying contact info using pen would also be easier for the same reason.
Paper type non-glossy for usability reasons. Reflecting light on QR code makes it impossible or extremely hard for camera to capture, if camera uses flash than it becomes impossible for it to comprehend QR code.
