Correct Answer - Option 1 : Barcode

The correct answer is Barcode.

  •  The technique used is Barcode.
    • Barcode is a printed series of parallel bars or lines of varying width that is used for entering data into a computer system.
    • The bars are used to represent the binary digits 0 and 1, sequences of which in turn can represent numbers from 0 to 9 and be processed by a digital computer.
    • A barcode scanner will read this pattern of black and white bars and translate them into a line of tests that your retail point of sale system can understand.
  • RFID- Radio Frequency Identification
    • It refers to a wireless system comprised of two components: tags and readers.
    • RFID tags are a type of tracking system that uses radiofrequency to search, identify, track, and communicate with items and people.
  •  MICR- Magnetic Ink Character Recognition
    • It is a technology used primarily to identify and process checks.
    • The MICR on a check is the string of characters that appears at the bottom left of the check.
    • It consists of three groups of numbers, including the bank routing number, the account number, and the check number.
  •  OCR- Optical Character Recognition
    • It is a widespread technology to recognize text inside images, such as scanned documents and photos.
    • It is used to convert virtually any kind of image containing written text (typed, handwritten, or printed) into machine-readable text data.
