QR Codes in Manufacturing
Definition: Manufacturing QR codes track parts through production, provide work instructions at stations, log quality inspections, and manage equipment maintenance.
QR codes originated in manufacturing (Toyota, 1994) and remain essential. Modern applications include: parts tracking through assembly stages, digital work instructions at each station (replacing paper SOPs), quality inspection logging with photo evidence, equipment maintenance schedules, and finished goods traceability. QR codes are preferred over barcodes because they survive industrial conditions better and store more data per label.

Frequently asked questions
How did QR codes originate in manufacturing?
Denso Wave (Toyota subsidiary) invented QR codes in 1994 to track auto parts. They needed a code that could be scanned faster than barcodes from any angle.
Why are QR codes better than barcodes in factories?
QR codes scan from any angle (360°), survive partial damage, hold more data, and work with smartphones — no dedicated scanner hardware needed.
Can QR codes handle harsh factory environments?
Yes — laser-etched QR codes on metal parts, chemical-resistant labels, and high-temp rated materials ensure readability in industrial conditions.
