QR = Quick Response
• In 1994, Japanese company Denso Wave Incorporated (a subsidiary of Toyota) developed the first QR code
• Denso Wave needed an easily scannable code that could store more data than traditional bar codes
History
• Traditional bar codes can store up to 20 characters
• QR codes can store 7,089 numeric and 4,295 alphanumeric characters
• The 2D (two-dimensional) design of QR codes allows it to hold more data than bar codes
