ID Card Glossary
- 1D Barcode
A one dimensional (1D) barcode is a machine-readable representation of data directly relating to the object it is attached to. A traditional 1D barcode consists of parallel lines that represent numbers or characters. The barcode is read from left to right and can be scanned using a barcode scanner. The most common 1D barcode symbologies are the EAN-13 and EAN-8, UPC-A and UPC-E, Code 128, ITF, and Code 39.
- 2D Barcode
A two-dimensional (2D) barcode, also known as a quick response code (QR Code), is a machine-readable image attached to items that allows data to be accessed quickly. It stores more information than a one dimensional barcode.
A series of letters, numbers, punctuation marks, and symbols that can be processed by a computer.
Acronym for the American National Standards Institute. Founded in 1918, ANSI is a voluntary organization composed of over 1,300 members (including all the large computer companies) that creates standards for the computerindustry.

Also known as Comma Separated Values, this file format is a way to store large amounts of data. Commas separate the data values and include a header describing what data is populating the file. The most popular program to write and maintain .csv files is Microsoft Excel, but Notepad and other minimal text-editors can also be used to read and write .cvs files.
- CAC (Common Access Card)
A "smart" card that is the size of a credit card. Most commonly, CAC cards enable physical access to buildings and controlled spaces. It can also provide access to computer networks and systems. It uses ditigal signatures and data encryption technology, such as authentication, integrity and non-repudiation. The CAC contains a PDF417 barcode on the front of the card and a Code 39 barcode on the back.
Code Division Multiple Access is a digital wireless technology for communication between devices and is also used by major cell phone carriers like Sprint and Verizon Wireless. CDMA employs "spread-spectrum" technology, which means that it spreads the information contained in a particular signal of interest over a much greater bandwidth than the original signal. Special coding in CDMA allows it to have no hard limit on the number of users who may share one base station.
- Check Character

- Dot Matrix
A 2-dimensional pattern of dots that is used to represent clear and accurate characters, symbols, or images. The human eye blends the dots together to create a coherent image. Therefore, the more dots used, the more coherent and clear the image appears to be. They are used for electronic displays, including cell phones, televisions, computer screens, LED screens and printed output. For example, a newspaper is made up of dot matrixes, but it is difficult to notice unless you look very closely at the paper.
Dots per inch (DPI) is a measurement of printer resolution that defines how many individual dots can be placed in a line within the span of 1 inch when the image is printed. DPI is commonly confused with PPI. DPI refers to the resolution of the printer, where as PPI refers to the resolution of the image itself. Photo-quality ink jet printers have a DPI resolution in the range of 1200 to 4800 dpi.
Dynamic random access memory, or DRAM, is the most common type of computer memory. It is particularly useful for computers as it can hold a lot of data in a small physical space. However, it does not usually retain data when its power supply is switched off, meaning that it isn't suitable for permanent storage.
Software and/or firmware that controls hardware and often connects an operating system with specific hardware devices, allowing them to properly work in unison. Software refers to a program sunning on hardware while firmware is a semi-permanent software that is placed into the hardware. Firmware does not disappear when the hardware is turned off and, in order to change the firmware, it must be done by a special installation process.

A common example is when a scanner converts a barcode into a human readable format onto a PC.
The point of interaction between hardware and/or software components. These components function independently while using the interfaces to communicate with each other through an input/output system and an associated protocol. The most common interface is USB.
- Interleaved 2 Of 5 Code (I 2 of 5)
Interleaved 2 of 5 is a continuous two-width barcode symbology that encodes any even number of numeric characters in widths and spaces of a barcode. The symbology is called "interleaved" because the first digit is encoded in the five bars (or black lines), while the second digit is encoded in the five spaces (or white lines). This way, the first 5 bars and spaces actually encode two characters. Interleaved 2 of 5 is typically used in the distribution and warehouse industry.
- Inventory Management
This is the process of efficiently tracking and controlling the constant flow of items in and out of an existing inventory; preventing it from becoming too high, or dwindling to levels that could put the company's operation in jeopardy. Competent inventory management also seeks to control the costs associated with the inventory, both from the perspective of the total value of the goods included and the tax burden generated by the cumulative value of the inventory.
- IP Rating
The Ingress Protection (IP) Rating classifies and measures the degree of protection a device offers from the intrusion of solid objects such as body parts, dust, accidental contact, and water into its electrical enclosures. The digits following "IP" represent the conformity with certain conditions. The first number is the level of solid particle protection the device offers, while the second number refers to its amount of liquid ingress protection. The higher the numbers, the more durable and rugged the device is. If a condition does not have a protection rating, it is marked with the letter X. An IP22 or IP2X are typical minimum requirements for the design of indoor electrical accessories.
