The History of QR Codes
From Automotive Factories to Global Phenomenon
QR codes (Quick Response codes) were invented in 1994 by Masahiro Hara, an engineer at Denso Wave, a subsidiary of Toyota. Their original purpose? To track automotive parts during manufacturing. Unlike traditional barcodes, QR codes could store 100x more data and be scanned at high speeds.
Key Milestones:
