Have you seen those digital boxes on coupon books or in a printed advertisement and wondered what they were?  They are called QR codes or Quick Response codes. 

Believe it or not, those small, coded boxes can be incredibly helpful to businesses.  They can be used to invite someone to an event or to hold contact information.  Best of all, they are free! 

All you need to read a QR code is QR code scanning software and a camera phone.  So yes, there is an app for that.

Want an app to read QR codes?  I have used and like the following:   

i-nigma

Quickmark

Want to create your own?  I have found both of these sites incredibly helpful:

qrstuff

qurify

Want my contact information?  Scan the following QR code with your new QR reader.
