Optimizing the length of the resulting barcode is important when barcode readers are used which must detect the entire barcode image at once in order to read it, such as common laser scanners. The longer the barcode is, the greater distance of laser barcode reader from barcode image is needed, making reading difficult or impossible above some ...
Barcode library or Barcode SDK is a software library that can be used to add barcode features to desktop, web, mobile or embedded applications. Barcode library presents sets of subroutines or objects which allow to create barcode images and put them on surfaces or recognize machine-encoded text / data from scanned or captured by camera images with embedded barcodes.
ZBar is an open-source C barcode reading library with C++, Python, [2] Perl, and Ruby bindings. [3] [4] [5] It is also implemented on Linux and Microsoft Windows as a command-line application, [6] and as an iPhone application. [7] It was originally developed at SourceForge. [8]
A barcode system is a network of hardware and software, consisting primarily of mobile computers, printers, handheld scanners, infrastructure, and supporting software. Barcode systems are used to automate data collection where hand recording is neither timely nor cost effective.
MaxiCode is a public domain, machine-readable symbol system originally created by the United Parcel Service (UPS) in 1992. [1] Suitable for tracking and managing the shipment of packages, it resembles an Aztec Code or QR code, but uses dots arranged in a hexagonal grid instead of square grid. MaxiCode has been standardised under ISO/IEC 16023. [2]
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 ...
Thus a (15,10) or (15,9) Reed-Solomon code (shortened to (7,2) or (10,4) respectively), over GF(16) is used. Because an L+1-layer compact Aztec code can hold more data than an L-layer full code, full codes with less than 4 layers are rarely used. Most importantly, the number of layers determines the size of the Reed–Solomon codewords used.
DotCode barcode can be used in the same way as Code 128 or any (2D) matrix barcode. At this time, it is used mostly to encode GS1 data in tobacco, [10] [11] alcoholic and non-alcoholic beverage, [12] pharmaceutical and grocery industries. The main implementation at this time is in tobacco industry. [13] [14]
