A code is a set of symbols or signals that usually represent alphanumeric characters. Nearly all the automatic identification technologies consist of three principal components, which also comprise the sequential steps in AIDC: ( July 2021) ( Learn how and when to remove this template message) Unsourced material may be challenged and removed.

Overview of automatic identification methods These automated wireless AIDC systems are effective in manufacturing environments where barcode labels could not survive.
RFID has found its importance in a wide range of markets, including livestock identification and Automated Vehicle Identification (AVI) systems because of its capability to track moving objects. The technology acts as a base in automated data collection, identification, and analysis systems worldwide. Radio-frequency identification is relatively a new AIDC technology, which was first developed in the 1980s. In biometric security systems, capture is the acquisition of or the process of acquiring and identifying characteristics such as finger image, palm image, facial image, iris print, or voiceprint which involves audio data, and the rest all involve video data. Capturing data can be done in various ways the best method depends on application. The file is then stored and at a later time, it can be analyzed by a computer, or compared with other files in a database to verify identity or to provide authorization to enter a secured system. To capture data, a transducer is employed which converts the actual image or a sound into a digital file. ĪIDC is the process or means of obtaining external data, particularly through the analysis of images, sounds, or videos. AIDC is also commonly referred to as "Automatic Identification", "Auto-ID" and "Automatic Data Capture". Technologies typically considered as part of AIDC include QR codes, bar codes, radio frequency identification (RFID), biometrics (like iris and facial recognition system), magnetic stripes, optical character recognition (OCR), smart cards, and voice recognition. ( July 2021)Īutomatic identification and data capture ( AIDC) refers to the methods of automatically identifying objects, collecting data about them, and entering them directly into computer systems, without human involvement.
