Wand (Contact)
|
|
A wand is typically made from 1/2" stainless steel tubing or from plastic; the optics are in the front with a cord out the back. The wand scanner must be moved by the user's hand across and in contact with the bar code. While the wand is moving across the bar code, the reflected light is converted to electrical signals through a photocell in the wand.
|
| |
"Gun" Type
|
|
Can be non-contact or near-contact scanner, which generally uses a beam of focused light to read the bar code. The most common form of active non-contact scanner uses a laser beam that is automatically scanned back and forth across the symbol at a high rate. Near-contact scanners utilize a CCD device. Active non-contact or near-contact scanners may be stationary as an option.

Bar code symbologies are essentially alphabets in which different widths of bars and spaces are combined to form characters and, ultimately, a message. Because there are many ways to arrange these bars and spaces, numerous symbologies are possible. Consult with a scanner manufacturer for help in choosing a bar code type, or determining which bar code you are currently using.

Codablock
|
|
Codablock was developed as a stacked version of the standard bar codes Code 39 and Code 128. Each row is structured so that it conforms fully to the rules of the basic encodation symbology.
|
| |
Codabar
|
|
Also known as USD-4, NW-7, and Code 2 of 7, Codabar is a self-checking, numeric only code. Codabar can encode the digits 0 through 9, six symbols (- : . $ / +), and the start/stop characters A, B, C, D, E, *, N, or T. Codabar is used in libraries, blood banks, the overnight package delivery industry, and a variety of other information processing applications.
|
| |
Code 1
|
|
Code 1 is considered an "area type" symbology that combines a checkerboard data area with a bar code-like locator pattern. It can label very tiny components as well as carry large amounts of information in larger symbols. This symbology allows the user to encode up to 2218 alphanumeric characters into a single symbol. Code 1 symbols can be shaped to fit in non-rectangular shapes like an L, U, T or other shapes.
|
| |
Code 11
|
|
Code 11 is used primarily for labeling telecommunications equipment. The character set includes the digits 0 through 9 and a dash. Each character is encoded with three bars and two spaces.
|
| |
Code 128
|
|
Code 128 provides excellent density for all-numeric data and good density for alphanumeric data. The Code 128 standard is maintained by AIM (Automatic Identification Manufacturers).
|
| |
Code 16K
|
|
Code 16K has 37 alphanumeric characters or 74 numeric characters. It employs a fixed-width, variable-height (2 to 16 rows) pattern. It is derived from the Code 128 symbology.
|
| |
Code 39
|
|
Code 39, also known as Code 3 of 9 or USD-3, is widely used in many industries and is the standard for many government barcode specifications, including the U.S. Department of Defense. Code 39 is defined in American National Standards Institute (ANSI) standard MH10.8M-1983.
|
| |
Code 49
|
|
Code 49 was the first two-dimensional symbology that could be read by traditional scanners. This symbology can encode 49 alphanumeric characters or 81 numeric characters in 1.25 x 1.25 inches. Each row contains eight characters, with each character having 49 possible values (hence the name of the code).
|
| |
Code 93
|
|
Code 93 is a more compact version of Code 39. It encodes exactly the same characters as Code 39, but uses 9 barcode elements per character instead of 15.
|
| |
Data Matrix (Data Code)
|
|
VeriCode and DataMatrix are usable like traditional bar codes helping computers access a particular file of information. The symbol itself can also contain that information. Each square in the symbol is a data cell. Algorithms contained in each cell identify the information that has been encoded. Upwards of 2000 ASCII characters may be encoded in a symbol. This code is very popular for applications that require a very tiny symbol size.
|
| |
EAN
|
|
EAN / JAN is an abbreviation for 'European Article Numbering / Japanese Article Numbering.' EAN-13 is used worldwide for marking retail goods. It encodes 13 characters: the first two are a country code, followed by 10 data digits and a checksum. 2-digit and 5-digit supplemental bar codes may be added for a total of 14 or 17 data digits. EAN-8 code is a shortened version of the EAN-13 code. It includes a 2-digit country code, 5 data digits, and a checksum digit. 2-digit and 5-digit extension bar codes may be added.
|
| |
Interleaved 2 of 5
|
|
Interleaved 2 of 5 is a numeric-only bar code widely used in warehouse and industrial applications. The data must consist of an even number of digits.
|
| |
Matrix 2 of 5
|
|
Industrial 2 of 5, Matrix 2 of 5, & Standard 2 of 5 are numeric-only bar codes that have been in use a long time. Unlike Interleaved 2 of 5, all of the information is encoded in the bars; the spaces are fixed width and are used only to separate the bars. The code is self-checking and does not include a checksum.
|
| |
MaxiCode
|
|
MaxiCode is fixed-size two-dimensional matrix bar code that can encode all 256 ASCII characters. It contains 866 hexagons arranged around a central bulls eye finder. MaxiCode can be read quickly from most directions. United Parcel Service uses it in automated sorting operations.
|
| |
MSI / Plessey
|
|
The Plessey bar code is a pulse-width modulated non-self checking code. Each character consists of eight elements, four bars and four spaces. The character set includes the digits 0 through 9 and the upper case letters A through F. Plessey bar codes are used primarily in libraries. The MSI Plessey bar code is a variant of the Plessey bar code, and is used primarily in store shelf labeling. A Modulo 10 checksum is appended to the end of the code.
|
| |
NW-7 Code
|
|
NW-7 Code, named for its composition of two type of bars, Narrow and Wide, is also known as Codabar.
|
| |
PLANET
|
|
PLANET is a bar code that will track both inbound and outbound letter mail. The PLANET bar codes complement the existing POSTNET barcodes. The PLANET bar codes are required by the U. S. Post Office to use their new CONFIRM service.
|
| |
POSTNET
|
|
The POSTNET barcode is used by the United States Postal Service to automatically sort mail. The POSTNET code consists of evenly spaced bars of two different heights. Each character is represented by five bars, two tall and three short. The character set includes the digits 0 through 9. The code begins and ends with a tall bar ('frame bar'), and may contain a 5-digit ZIP code, a 9-digit ZIP+4 code, or an 11-digit Delivery Point Code. A Modulo 10 check digit is inserted after the ZIP code and before the ending frame bar.
|
| |
Telepen
|
|
A European code capable of encoding the full ASCII set. Additionally, it offers a compressed numeric mode enabling numeric data to be encoded at twice the density of the standard mode. It is a wide-narrow symbology with a fixed 3:1 wide: narrow ratio.
|
| |
UPC
|
|
UPC-A is used for marking products that are sold at retail to the public. The barcode identifies the manufacturer and specific product so point-of-sale cash register systems can automatically look up the price. UPC-E is a variation of the UPC-A symbol that is used for number system 0. By suppressing zeroes, UPC-E codes can be printed in a very small space and are used for labeling small items. The Uniform Code Council located in Dayton, Ohio controls the UPC-A Code and the assignment of manufacturer ID numbers in the U.S.A.
