Recently, through the Free Technology for Teachers Facebook page I was asked for suggestions for tools for creating QR codes. Here are five suggestions that I often make in regards to creating and using QR codes in classrooms.
Russel Tarr developed the QR Treasure Hunt Generator. The QR Treasure Hunt Generator provides you with all of the things you need to get started creating your own QR codes and using them in your classroom. To use the QR Treasure Hunt Generator type out a series of questions and answers, generate the QR codes using the tool Russel Tarr provides, then print and display the codes around your classroom or school.

Goo.gl is Google's URL shortening tool. When you shorten a link with Goo.gl a QR code is created for it too. To find the QR code, click the "details" link after your shortened URL has been made. The details page also shows you how many times your link has been used. This is useful to me if I want to make sure that all of my students have used the link. If I see that the link or QR code has been used 17 times, but I have 25 students, I immediately seek out the students who haven't followed the link.
QR Droid's QR Code Generator allows you to create QR codes that link to websites, chunks of text, phone numbers, email addresses, contact information, calendar events, and location coordinates. To create your QR code simply complete the information fields that you want to link to then select the display size for your QR code.
QR Voice is a free tool that allows you to create QR codes that when scanned will play a short audio message. To create your message and QR code you can record a voice message by clicking the microphone icon on QR Voice or you can type in your message. Either way you're limited to 100 characters. QR Voice is offered in Spanish, English, Japanese, and Portuguese. Teachers could use QR Voice to create QR codes that they then print and attach to objects in their classrooms or schools. Then have students try to identify those objects in the language that they're trying to learn. To check their answers students can scan the QR code and hear the correct answer on their phones or tablets.
TagMyDoc is a tool that allows you to apply a QR code to Word documents and PDFs that are stored on your computer. Upload your document then TagMyDoc creates and applies a QR code to it. You can print the document with the QR code on it or simply project the QR code for your students to scan and get a copy of the document on their mobile devices.
