As mobile learning and technology is more readily integrated within classroom settings, QR codes can be used as an interesting method to capture a student's attention and make lesson material more interactive. Quick response codes, also known as 'QR' codes, are simple, scannable images that are a form of barcode. By scanning a QR code image through a mobile device, information can be accessed including text, links, bookmarks and email addresses. In the classroom, QR codes can be used in a variety of ways -- from conducting treasure hunts to creating modern CVs.
QR Codes (Quick Response Codes) are just barcodes. There is nothing fancy about them. Just like the grocery store clerk uses barcodes to look up the product and scan the price into the computer, your mobile device or computer can look up QR codes to: take you to a website, read some text, give you a phone number, or generate a text message.
