I've always been fascinated with QR codes, and how the placement of (black) dots translates to a message, URL, or other information. QR.io makes it easy to make a new Quick Response (QR) code. You can customize the color, code shapes, and information the QR code represents. The price makes it an easy buy, and the LTD is a no-brainer. The UI is easy to use and navigate. Overall, happy with the purchase.
