QR Codes

QR Codes are starting to appear everywhere. I’m intrigued and I want to know more about them. Here are some links I dug up and hope to return to:

• Wikipedia on QR codes
   
• Schubart’s Wikipedia on QR codes
   
• jphonegames on QR codes
   
• QR code generator
   
• QR codes and PHP
   
• A better QR code generator
