In 1994, engineer Masahiro Hara of Denso Wave developed the Quick Response Code in Japan to improve automotive parts tracking. Inspired by the board game Go, Hara designed a two-dimensional code capable of storing significantly more data than traditional one-dimensional barcodes, which previously required multiple labels per component.
The technology features three iconic corner squares allowing scanners to read data accurately in milliseconds, even if the code is tilted or folded. Furthermore, the system includes an Error Correction feature, ensuring data remains readable even if up to 30 percent of the physical code is damaged or dirty.
Denso Wave chose not to patent the technology, releasing it for free global use. This decision facilitated widespread adoption, particularly as smartphone cameras became ubiquitous in the 2010s, transforming the code from a manufacturing tool into a bridge between physical and digital environments.
In Indonesia, the technology reached a milestone in 2019 with the launch of the Quick Response Code Indonesian Standard (QRIS) by Bank Indonesia. This initiative unified various digital payment systems, allowing merchants to accept transactions from any digital wallet or banking application through a single, standardized code.
