CCD reader:
A scanning device which uses the CCD technology. CCD is an acronym for Charge
Coupled Device. Light from a lightsource within the CCD reader is reflected by a bar
code label and falls on an array of light sensitive elements in the reader, the CCD.
Whether the light is reflected depends on black or white parts of the bar code. The
presence (or absence) of reflected light determines the presence (or absence) of
electrical charge (electrons) in the distinct elements. The result is an electrical image
of the bar code which can be used for further processing.
Character:
A single group of bars and spaces which represent an individual number, letter or
punctuation mark. It is usually composed of six, seven or eight bits.
Check digit:
A character included within a symbol whose value is based, mathematically, on other
characters within the symbol. It is used to perform a mathematical check to ensure the
accuracy of the read.
CMOS interface:
A serial interface that typically is used between embedded devices. The CMOS
standard defines a logical "1" level at the same level as the power supply of the
electronic components that are used inside the device.
CMOS imager:
A scanning device, which uses the CMOS technology. CMOS is an acronym for
Complementary Metal Oxide Semiconductors. Light from a light source within the
CMOS is reflected by a bar code label and falls on an array of light sensitive elements
in the scanner, the CMOS sensor. Whether the light is reflected depends on black or
white parts of the bar code. The presence (or absence) of reflected light determines
the presence (or absence) of electrical charge (electrons) in the distinct elements. The
result is an electrical image of the bar code, which can be used for further processing.
Composite code:
A bar code label that consists of two parts of two different symbologies: a linear (1D)
part and a composite (2D) part. The composite part holds meta information about the
product (like manufacturing date, quantity, etc.), while the linear part holds the
product identification code.
Data:
Digital information.
