Frequently Asked Questions

Masahiro Hara led the small DENSO development team credited with creating QR Code. DENSO announced the technology in 1994 for fast reading and greater data capacity in manufacturing. Check the final destination, mobile layout, and printed placement before distributing the code to users.

QR stands for Quick Response. The name reflects the development team's focus on creating a two-dimensional code that equipment could detect and read quickly. Use a destination you control and review it periodically so long-lived printed material does not lead to an error.

The three finder patterns help a scanner locate the symbol and determine its orientation. Their distinctive pattern was designed to be unlikely to appear accidentally in surrounding printed material. Test the complete journey on multiple phones under the lighting, distance, and network conditions expected in normal use.

No. QR Code was released in 1994, standardized internationally in 2000, and reached consumer phones in Japan by 2002. The pandemic later accelerated some contactless uses but did not create the technology. Keep a readable destination or contact route nearby so users still have an option when scanning is unavailable.
