![]() In barcode terminology, it refers to a type of barcode reader that utilizes light-emitting diodes (LEDs) rather than a laser.Ĭharacter added to prevent undetected errors. Not all barcode types encode the same kinds of characters.Ī device that moves an electrical charge to an area that it can be converted. This can be caused by ink or toner blobs, or running out of ink or toner.Īvailable character to encode in a barcode. What percent of the total measured bar height has spots or voids. When a barcode can be read when scanned in either direction. The amount by which the bar width is reduced to compensate for print gain or bar width growth. The thickness of a bar measured from the edge closest to the symbol start character to the trailing edge of the same bar. Scanning occurs in an axis perpendicular to the bar length. The bar dimension perpendicular to the bar width. The maximum number of characters that can be represented in a linear unit of measure, which is often written as characters per inch or CPI. The barcode character is the smallest part of a symbol that holds data. This format is easily read by a barcode reader and can store real-time data.Ī single group of bars and stripes that represents a specific quantity (usually 1) of letters, numbers, punctuation marks, or other symbols. The darker element of a printed barcode symbolĪ series of vertical bars or a bar pattern that can encode numbers and letters( contingent on width and pattern). The area surrounding a symbol including spaces and quiet zones. The average of the background reflectance from at least five different points on the sheet (in percentage form) For example, voice recognition, barcodes, RFID, etc. The ability for one barcode reader to recognize different symbologies and interpret several different codes.ĭifferent processes that let machines identify objects independent of human intervention. The ratio of the bar’s height to the symbol’s length. The ASCII set has both control and printing characters. Each ANCII character is encoded with 7 bits and utilized for information interchange between data processing systems, communication systems, and other associated equipment. The character set and code set forth in the American National Standard Code for Information Interchange, ANSI X3.4-1977. For example, pharmaceutical applications, Department of Defense applications, etc. ![]() The use a label, tag or ticket will serve once the bar code is applied. The opening on a scanner that provides the field of view. This group is part of the International Standards Organization (ISO). The position and orientation of a symbol relative to the scanner.Īmerican National Standards Institute (ANSI)Īn NGO that develops voluntary barcode quality standards for the United States. The determination if any element width or inter-character gap width differs from its nominal width by an amount greater than the printing tolerance.Īutomatic Identification Manufactures Organization (AIM)Īn organization supported by manufacturers and vendors of automatic identification products.
