Frequently Asked Questions Q. What is AIDC? A. AIDC is the is the acronym for automatic identification and data collection (or capture). Automatic identification, or auto ID for short, is the broad term given to a host of technologies that are used to help machines identify objects. Auto identification is often coupled with automatic data capture. That is, companies want to identify items, capture information about them and somehow get the data into a computer without having employees type it in. The aim of most auto-ID systems is to increase efficiency, reduce data entry errors, and free up staff to perform more value-added functions, such as providing customer service. There are a host of technologies that fall under the auto-ID umbrella. These include bar codes, smart cards, voice recognition, some biometric technologies (retinal scans, for instance), optical character recognition, and radio frequency identification (RFID). Q. What is RFID (radio frequency identification)? A. Radio frequency identification, or RFID, is a generic term for technologies that use radio waves to automatically identify people or objects. There are several methods of identification, but the most common is to store a serial number that identifies a person or object, and perhaps other information, on a microchip that is attached to an antenna (the chip and the antenna together are called an RFID transponder or an RFID tag). The antenna enables the chip to transmit the identification information to a reader. The reader converts the radio waves reflected back from the RFID tag into digital information that can then be passed on to computers that can make use of it. Q. What is UID (unique identification)? A. UID is a Department of Defense program that will enable easy access to information about DoD possessions that will make acquisition, repair, and deployment of items faster and more efficient. UID of items is accomplished by marking each qualifying item with a permanent 2-dimensional data matrix. The data matrix is encoded with the data elements necessary to construct a Unique Item Identifier (UII) which is globally unique and unambiguous. The data elements required to form a UII include the manufacturer’s identification (i.e. cage code) and the item’s serial number. If the manufacturer serializes within part number, that data element will also be encoded. The DOD website for UID is: http://www.acq.osd.mil/dpap/UID/index.htm |
