Bar Code Scanner Type
   Bar Code Scanner Type       
   Your choices are...         
   Fixed Horizontal / In-counter       A horizontal fixed scanner is basically a tabletop, where the code is passed over the scanner face. 
   Fixed Vertical / Counter-top       A vertical fixed scanner sits on top of a counter or stand where the code is passed in front of the scanner face. 
   Handheld 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. 
   Handheld "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. 
   Handheld "Gun" Type with Optional Fixed Mount       The "gun" type reader has an optional fixed mounting accessory. 
   Slot Card       Slot card bar code scanners are designed to read imprinted bar code cards that are passed through the aperture on the reader.

Light Source
   Light Source       
   Your choices are...         
   LED / CCD       CCD stands for Charge Coupled Device, which uses one or more LEDs to flood the bar code area with light, and an image of the code is transferred to an array of photodetectors. It is a near contact or contact device, with a smaller depth of field than a laser. 
   Infrared Light       For security reasons, sometimes a "black-on-black" bar code is used, and in this case, an infrared light bar code reader must be used.  The reader can also read visible bar codes. 
   Visible Light       A visible light scanner is used if the actual bars and lines of the bar code can be seen with the human eye. 
   Laser       Uses a laser diode to create a scan line by projecting a beam of energy off a rotating mirror or prism. It is a non-contact device allowing for a large depth of field. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Laser Class       
   Your choices are...         
   Class I       Class I lasers are not hazardous for continuous viewing, or are designed to prevent human access to laser radiation. Class I lasers include both low-power lasers and embedded, high-powered lasers. Applications include laser printers. 
   Class II       Class II lasers emit visible light which, because of the normal human aversion response, does not normally present a hazard. If viewed directly for extended periods of time, however, Class II lasers can cause eye injuries. 
   Class III       Class III includes Class IIIa and Class IIIb lasers.  Class IIIa lasers will not normally injure the eye if viewed momentarily, but present a hazard if viewed using collecting optics. Class IIIb lasers present an eye and skin hazard if viewed directly. This includes both intrabeam viewing and specular reflections. Class IIIb lasers do not produce a hazardous diffuse reflection except when viewed at close proximity. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Interface Options
   Interface Options       
   Your choices are...         
   Ethernet       A local-area network (LAN) protocol developed by Xerox Corporation in cooperation with DEC and Intel in 1976. Ethernet uses a bus or star topology and supports data transfer rates of 10 Mbps. The Ethernet specification served as the basis for the IEEE 802.3 standard, which specifies the physical and lower software layers. Ethernet uses the CSMA/CD access method to handle simultaneous demands. It is one of the most widely implemented LAN standards. 
   Integrated Graphic Display       LCD, etc. to indicate read or decoded info. 
   Keyboard Connection       This connection is usually made through a keyboard decoder wedge. 
   Modem       Modulator-demodulator. A modem is a device or program that enables a computer to transmit data over telephone lines. Computer information is stored digitally, whereas information transmitted over telephone lines is transmitted in the form of analog waves. A modem converts between these two forms. 
   Parallel       A standard digital output protocol (parallel) such as IEEE488, Centronics port, printer port, etc. 
   Serial       A standard digital output protocol (serial) such as RS232, RS422, RS485, etc. 
   PCMCIA (PC Card)       PCMCIA devices (PC Cards) are credit-card-sized peripherals predominantly used in laptop computers. The PCMCIA adapter takes the place of a COM port on a standard bus. The card is plugged into a 68-pin host socket that is connected either to the motherboard or an expansion bus. An adapter then translates the PCMCIA signals into signals usable by the computer's bus. 
   Wand or Laser Emulation       This is output, which needs external decoder. 
   Wireless       A wireless interface such as RF or IR. 
   Other       Outputs a digital signal other than parallel or serial (i.e., special TTL).

Symbologies
   Symbologies       
   Your choices are...         
   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. 
   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. 
   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 bull’s 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. 
   QR Code       The QR Code, or Quick Response Code, is a 2-D matrix code which can code up to 7089 numeric or 4296 alphanumeric characters. 
   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. 
   VeriCode       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. 
   Other Symbology       Unlisted, specialized, or proprietary configuration.
