Barcode reader. A stationary barcode scanner for a conveyor line. 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.
Magnetic ink character recognition code, known in short as MICR code, is a character recognition technology used mainly by the banking industry to streamline the processing and clearance of cheques and other documents. MICR encoding, called the MICR line, is at the bottom of cheques and other vouchers and typically includes the document-type ...
Automatic identification and data capture. Automatic identification and data capture ( AIDC) refers to the methods of automatically identifying objects, collecting data about them, and entering them directly into computer systems, without human involvement. Technologies typically considered as part of AIDC include QR codes, [1] bar codes, radio ...
A barcode or bar code is a method of representing data in a visual, machine-readable form. Initially, barcodes represented data by varying the widths, spacings and sizes of parallel lines. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called barcode readers, of which ...
Radio-frequency identification ( RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder called a tag, a radio receiver, and a transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits ...
Instruction code - indicates the specific command, e.g., "select", "write data" P1-P2 2 Instruction parameters for the command, e.g., offset into file at which to write the data L c: 0, 1 or 3 Encodes the number (N c) of bytes of command data to follow 0 bytes denotes N c =0 1 byte with a value from 1 to 255 denotes N c with the same length
High Capacity Color Barcode. 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] Data density is increased by using a palette of 4 or 8 colors for the triangles ...

A Barker code or Barker sequence is a finite sequence of N values of +1 and −1, with the ideal autocorrelation property, such that the off-peak (non-cyclic) autocorrelation coefficients. are as small as possible: for all . [1] Only nine Barker sequences [6] are known, all of length N at most 13. [7] Barker 's 1953 paper asked for sequences ...
The Aztec Code is a matrix code invented by Andrew Longacre, Jr. and Robert Hussey in 1995. [1] The code was published by AIM, Inc. in 1997. Although the Aztec Code was patented, that patent was officially made public domain. [2] The Aztec Code is also published as ISO/IEC 24778:2008 standard.
