What is a QR Code?

A QR Code® is a 2D code developed by DENSO WAVE in 1994, and is most commonly used in Japan.

Features of the QR Code®

Feature 1: Encoding a large amount of data with a small code

A QR Code® can encode numerals, alphabetical characters, kanji characters, katakana and hiragana characters, symbols, binary data, control codes and other data.

Feature 2: Printing in a small area

Since QR Codes encode data in the transverse and longitudinal directions, a QR code can represent data using approximately 10 times less space than a traditional barcode.

Feature 3: Readable regardless of the scanning angle

QR Codes® can be read at high speed regardless of the scanning angle. The secret lies in three position detection patterns, which are located in each code, enabling stable high-speed reading without being affected by the background patterns.

Feature 4: Resistant to dirt and damage

Since QR codes have an error correction function, data can be restored* even if a code is partially stained/missing.
* Data may be unable to be restored depending on the dirt/damage level.
