QR Code History

QR means “quick response”. QR codes were originally invented in Japan by Denso-Wave (a subsidiary of Toyota). The primary goal for QR codes was to help engineers and mechanics track machine parts as they are shipped and sorted in the manufacturing line. They then expanded its use to contain more information. Today QR Codes are an emerging standard for sharing information on mobile phones.
