What is data capturing?
Data extraction/capture is the process of gathering or extracting information from numerous sources and putting it into computer systems. The collected data is sometimes referred to as external data. This information is gathered in a variety of methods, such as through analysing sounds, photos, or movies. A transducer converts these sounds, movies, or pictures into digital forms. These files are saved, examined, and/or compared with other files in the database by a computer. Data capture devices include bar code scanners, biometrics, Radio Frequency Identification (RFID), magnetic stripes, voice recognition, smart cards, and Optical Character recognition(OCR).
Capturing data has several benefits. It is a useful tool in supermarkets and stores where goods are scanned using a bar code scanner, money transactions through ATMs where swiping the card authenticates the individual's identity and gives him/her access to their accounts, biometrics use data capturing to dispense punch cards and attendance registers at work places by taking finger prints, voice prints, and so on not only to update entry exit timings but also to check authenticity for approving admissions.
