This International Standard defines the requirements for the symbology known as QR Code 2005. It specifies
the QR Code 2005 symbology characteristics, data character encoding methods, symbol formats, dimensional
characteristics, error correction rules, reference decoding algorithm, production quality requirements, and
user-selectable application parameters, and lists in an informative annex the features of QR Code Model 1
symbols which differ from QR Code 2005.
