Barcodes have a long and storied history that begins in the USA in 1948. Over 60 years later, just about any retail item is packaged with one to facilitate pricing, keep inventory, or shipping. Anybody can buy a barcode. Otherwise known as upc codes, barcodes are simply machine-readable patterns of colored lines, blocks and circles; they can both encode data within the patterns according to a set symbology and link the patterns to a separate database to store various articles of information.
Barcodes have become ubiquitous in the modern age: they are a sign of machine-friendly organization, marketing, international standardization and wordless communication. Barcodes are used on merchandise, mail, medicine, and even man. As such a symbol of institutionalization, it seems counter-intuitive at first to create something as whimsical as art out of rigid barcodes.
Nevertheless a number of artists have turned their craft to representing and interacting with barcodes. Publicly able to purchase barcodes and scanners, through apps on smart-phones and similar portable media devices, barcodes which were designed to replace human interactivity with machine efficiency, now encourage humans to play and learn with some of the uses toward which they have been turned.
Scott Blake is one artist who integrates barcodes with artwork. Some works are collages of barcodes relevant to the whole piece, such as Barcode Elvis using the barcodes of Elvis Presley’s music CDs to represent a large-scale digital portrait of the singer. The barcodes in the portrait can be scanned by a barcode reader to access Elvis’s entire discography. A Japanese company, D-Barcode, integrates images into working merchandise barcodes. In these and other ways, barcodes have become a viable user interface.
