Quick Response (QR) codes are now easily recognized as the 'more information' feature on many store shelves, in many catalogs and frequently on product packaging.  When you order your Master CraftIDs we will generate the QR code for you based on information you provide.  If you need to or would like to create your own QR code there are many web-based resources such as ZXing.com (pronounced Zebra crossing dot com) and qrcode.Kaywa.com.
