Automatic identification and data capture or AIDC refers to the process involving identification of objects, collecting the related data, and entering it directly into computer systems or other microprocessor-controlled systems without resorting to the manual method of data entry. AIDC primarily consists of three principal technologies applied sequentially viz. data encoding, machine reading, and data decoding. Through the AIDC process, external data is obtained by analyzing sounds, images, or videos, wherein the received data may be in the form of videos, images, or sounds. In this process, the data is first converted into a digital file and then, entered into the computer system. A transducer is employed for converting the actual data into a digital file. After this, a database is fed into the computer system, after which the data file is analyzed by the computer. This data file is then compared with other files present in the database for verification or authentication before entering it in the secured system.
