38 ways to use QR Codes in
an Educational Setting
QR Code (abbreviated from Quick Response Code) is, according to wikipedia, the trademark for a type of matrix barcode or two-dimensional code. It was first designed for the automotive industry by the Toyota subsidiary Denso Wave in 1994 to track vehicles during the manufacturing process. It was designed to allow its contents to be decoded at high speed.
More recently, the system has become popular outside the manufacturing industry because of its fast readability and large storage capacity, which is greater than standard UPC barcodes. The code consists of black squares arranged in a pattern on a white background. The information encoded can be made up of four standardized kinds ("modes") of data (numeric, alphanumeric, byte/binary, Kanji), or through supported extensions, virtually any kind of data. QR Code has in recent years become popular in consumer advertising, primarily because the explosion of smartphones "has put a barcode reader in everyone's pocket" for the first time.
