AUTOMATIC DATA CAPTURE

Capture is the process or means of obtaining external data, particularly images, sounds or videos for use at a later time. Capturing of data can be done in various ways; the best method depends on application. It also refers to the methods of recognizing objects, getting information about them and entering that data or feeding it directly into computer systems without any human involvement. Automatic Identification and Data Capture (AIDC) technologies include bar codes, RFID, OCR, magnetic stripes, smart cards and biometrics. AIDC is also referred as “Auto Identification” or “Auto ID”.

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 voice print which involves audio data and the rest all involves video data.

In Automatic data capture to capture a data, a transducer is employed which converts the actual image or a sound into a digital file. 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.

Most serious computer users are familiar with the term screen capture. The intent of a screen capture is to store the image on a monitor. Radio frequency identification (RFID) is relatively a new AIDC technology which was first developed in 1980’s. The technology acts as a base in automated data collection, identification and analysis systems worldwide. 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. These automated wireless AIDC systems are effective in manufacturing environments where barcode labels could not survive.

Automatic Data Capture is also known as Data Capture, Automatic data collection, Barcode scanning, Identification and Data capture and automated data capture.
