I have seen teachers use QR codes in a variety of ways and with all ages of students. I really like the way they allow younger students to access websites without having to login, open applications and type on a computer. A few of the uses I have seen include, taping a QR code on a book to take students to information or videos on the book topic. including a QR code in a newsletter to take students to a specific class-related website on a home device, and placing the codes on posters to take students to sites that complement learning within the classroom.
The most straightforward QR scanner. Totally free without advertisements. Works with iPhone, iPad, and iPod Touch. The user doesn't have to take a picture or press a button to scan. When the app is opened and the device focuses on a code the device automatically goes to that web address or shows the text, etc.
This tag reader is supposed to be universal; it should read all tags. Teachers can also use the Microsoft Tag creator program to create their own tags leading students to appropriate internet content without having to type in long URLs.
"QR app is the FASTEST QR Code reader in the app store & the very first iPhone app to automatically scan QR Codes in real-time. QR App was designed to be FAST & SIMPLE. This is the app all the other QR Code readers are based on."
