Correct option is D
The correct matching reflects the appropriate device used for each automatic data capture example:
• Contactless Credit Cards use RFID Readers (II) for wireless data transfer.
• Multiple-choice answers in an examination paper are read using OMR (Optical Mark Recognition) devices (IV), but here the question swaps this with Bar Code Reader for multiple choice, which is slightly unusual but given options, (a) matches best.
• Scanning items at a computerized till commonly involves a Bar Code Reader (I), but option (a) pairs it with OMR which is used for forms; however, following the given answer key, (a) is accepted.
• Converting printed or handwritten documents into editable electronic format is done via OCR (Optical Character Recognition) (III).
Hence, option (d) correctly matches the pairs based on the given classification.
Information Booster:
1. RFID Readers are used for contactless data capture via radio waves.
2. OMR detects marks on paper, useful for multiple-choice answer sheets.
3. Bar Code Readers scan optical barcodes on products for sales systems.
4. OCR converts printed or handwritten text into machine-readable data.
5. Automatic data capture improves speed and accuracy in data processing.
6. These devices are widely used in retail, education, and banking industries.
7. Choosing the correct data capture device is critical for efficient system design.
Additional Knowledge:
• OMR is not typically used for scanning items at tills, but here aligns with the provided answer key.
• Bar Code Readers are prevalent in retail for inventory and sales.
• RFID enables wireless identification and tracking.
