An example of a High Capacity Color Barcode: a Microsoft Tag referring to the HCCB article on the English Wikipedia. High Capacity Color Barcode (HCCB) is a technology developed by Microsoft for encoding data in a 2D "barcode" using clusters of colored triangles instead of the square pixels conventionally associated with 2D barcodes or QR codes. [1]
The QR code system was invented in 1994, at the Denso Wave automotive products company, in Japan. [6] [7] [8] The initial alternating-square design presented by the team of researchers, headed by Masahiro Hara, was influenced by the black counters and the white counters played on a Go board; [9] the pattern of the position detection markers was determined by finding the least-used sequence of ...
Windows Live Barcode (codenamed Confucius) was a part of Microsoft's Windows Live services. It allowed users to transfer information between various media (PCs, billboards, magazines etc.) and handsets via Quick Response Code ( QR Code ), a two-dimensional matrix barcode .
This type requires special programming for transferring the input data to the application program. Keyboard interface scanners connect to a computer using a PS/2 or AT keyboard–compatible adaptor cable (a "keyboard wedge"). The barcode's data is sent to the computer as if it had been typed on the keyboard.
A barcode reader or barcode scanner is an optical scanner that can read printed barcodes and send the data they contain to computer. [1] Like a flatbed scanner , it consists of a light source, a lens, and a light sensor for translating optical impulses into electrical signals.
Interleaved 2 of 5 (ITF) is a continuous two-width barcode symbology encoding digits. It is used commercially on 135 film, for ITF-14 barcodes, and on cartons of some products, while the products inside are labeled with UPC or EAN. ITF was created by David Allais, who also invented barcodes Code 39, Code 11, Code 93, and Code 49.
The barcode scheme does not contain a check digit (in contrast to—for instance—Code 128), but it can be considered self-checking on the grounds that a single erroneously interpreted bar cannot generate another valid character. Possibly the most serious drawback of Code 39 is its low data density: It requires more space to encode data in ...
A barcode printer. A barcode printer is a computer peripheral for printing barcode [1] labels or tags that can be attached to, or printed directly on, physical objects. Barcode printers are commonly used to label cartons before shipment, or to label retail items with UPCs or EANs.
