- [QR Code — Denso Wave](https://www.qrcode.com/en/)

## Overview

**QR Code** (Quick Response Code) is **the world's most widespread 2D barcode standard**, originated **1994 by Masahiro Hara of Denso Wave** (subsidiary of Toyota Group's Denso Corporation) **for automotive-parts tracking** <sup>[1][1], [2][2], [3][3]</sup>. The technical specification is now standardised as **ISO/IEC 18004:2015** (current version), with prior versions dating back to **ISO/IEC 18004:2000**. **Denso Wave holds the patent rights but has chosen not to exercise them** — making QR Code **royalty-free for use anywhere worldwide** + driving its **explosive global adoption** in payment systems, marketing, ticketing, identification, manufacturing tracking, augmented-reality triggers, vaccination certificates, and countless other applications.

The structural significance: QR Code is **the foundational 2D barcode underlying virtually every modern QR-payment standard** discussed throughout this encyclopedia — from China's [Unified Cross-Border QR](https://docs.barcoder.ai/docs/standards/unified-cross-border-qr) to India's [UPI QR](https://docs.barcoder.ai/docs/standards/upi-qr) QR layer to Indonesia's [QRIS](https://docs.barcoder.ai/docs/standards/qris) to Thailand's [Thai QR](https://docs.barcoder.ai/docs/standards/thai-qr)/PromptPay to **EMVCo's MPM (Merchant-Presented Mode) + CPM (Customer-Presented Mode) QR Code Specifications**. The **EMVCo QR Code Specifications**, leveraging ISO/IEC 18004 QR Code as encoding layer, define **the payment-data structure inside the QR Code** that allows international interoperability across payment networks.

**Key QR Code characteristics**:
- **Data capacity**: Up to **7,089 numeric characters / 4,296 alphanumeric / 2,953 bytes / 1,817 kanji**.
- **40 versions** (sizes from 21×21 to 177×177 modules).
- **4 error-correction levels** (L/M/Q/H — 7% to 30% data recovery).
- **Reed-Solomon error correction**: Damaged QR codes still readable.
- **Position-detection patterns** (3 corner squares): Enable rotation + skew tolerance.
- **Module sizes** scale to allow printing on tiny labels to massive billboards.

**QR Code Variants**:
- **Micro QR Code** ([Micro QR](https://docs.barcoder.ai/docs/standards/micro-qr)) — smaller, lower-capacity for space-constrained applications.
- **iQR Code** ([iQR](https://docs.barcoder.ai/docs/standards/iqr)) — rectangular form factor.
- **SQRC** — restricted-readability for private data.
- **Frame QR** — frame around image (used for branding).
- **HCC2D** + others — color-extended variants.

## History

**1994 — QR Code invented by Masahiro Hara, Denso Wave** <sup>[2][2]</sup>:
- Toyota Group's Denso Wave automotive-parts tracking.
- Successor to 1D barcode limitations.

**1997 — AIM (Automatic Identification and Mobility) Global standard** <sup>[3][3]</sup>:
- First international standardisation.

**1999 — JIS X 0510 (Japanese Industrial Standard)** <sup>[3][3]</sup>:
- Japanese national standardisation.

**2000 — ISO/IEC 18004:2000** <sup>[1][1]</sup>:
- First ISO international standard.

**2006 — ISO/IEC 18004:2006** <sup>[1][1]</sup>:
- Updated standard.

**2015 — ISO/IEC 18004:2015 (current)** <sup>[1][1]</sup>:
- Latest standard revision.

**2010s — Explosive payment-adoption (China + India + global)** [[wiki-qr]]:
- WeChat Pay + Alipay + UPI + global QR-payment-systems built on QR Code.

**2020s — Pandemic-driven adoption + EMV QR specifications + cross-border QR-payment networks** [[wiki-qr]]:
- Massive scaling.
