A QR, or quick response, barcode is a machine-readable label, and encodes virtually any type of data including the standardised modes of alphanumeric, binary, numeric and what other kind?
QR code QR code QR code (abbreviated from Quick Response Code) is the trademark for a type of matrix barcode (or two-dimensional barcode) first designed in 1994 for the automotive industry in Japan. A barcode is a machine-readable optical label that contains information about the item to which it is attached. A QR code uses four standardized encoding modes (numeric, alphanumeric, byte/binary, and kanji) to store data efficiently; extensions may also be used. The Quick Response (QR code) system became popular outside the automotive industry due to its fast readability and greater storage capacity compared to standard UPC barcodes.

Machine-readable data and other formats machine readable but the documents must include enhanced structural elements." Machine-readable data Machine-readable data, or computer-readable data, is data (or metadata) in a format that can be easily processed by a computer. There are two types: human-readable data that is marked up so that it can also be read by machines (e.g. microformats, RDFa, HTML) or data file formats intended principally for processing by machines (RDF, XML, JSON). However, Extensible Markup Language (XML) is designed to be both human- and machine-readable, and Extensible Stylesheet Language Transformation (XSLT) is used to improve presentation of the data for human
