QR Codes

QR Codes are similar to bar codes in that they are read optically. Most-common in Japan, all Japanese cell phones can read them; all fancy phones in America (iPhone, etc.) have downloadable apps that can read QR Codes (semacode is a free QR Code app for the iPhone but there are many for all).

One application that is becoming common is encoding a website's URL and including the image in a print advertisement.

The QR Codes below were created by https://qrcode.kaywa.com/; create QR and semacode/DataMatrix from text: https://invx.com/code/.

I love QR codes. They are awesome and offer an unlimited amount of data to compliment a print ad. Cool stuff
