    Study Notes

    Direct Data Entry (DDE)

    • Direct Data Entry (DDE) devices input data into a computer with minimal human interaction.
    • Barcodes are a common example - a reader points at the barcode, and the data automatically transfers to the computer.

    Card Readers

    • Magnetic Stripe Readers
      • Used on credit/debit cards for ATMs and EFTPOS terminals.
      • Used as security devices for building and hotel room access.
    • Advantages of Magnetic Stripe Readers
      • Prevents access to restricted areas.
      • Unaffected by oil, water, moisture, etc.
      • Robust due to having no moving parts.
    • Contactless Debit Card Readers
      • Advantages
        • Faster transactions (approximately 10 seconds compared to 30 seconds for magnetic stripe readers).
        • Uses 128-bit encryption for data protection.
        • Eliminates typing errors by customers.
        • Retailers do not have access to customer card information.
        • Transactions use a unique, encrypted number for each transaction.
      • Disadvantages
        • More expensive than traditional credit/debit cards.
        • Potential for theft by someone with a suitable reader if PINs are not used.

    Radio Frequency Identification (RFID) Readers

    • RFID readers use radio waves to read information stored on a tag.
    • RFID tags have two components:
      • A microchip storing and processing information.
      • An antenna receiving and transmitting data.
    • Tags can be passive, powered by the reader's radio waves, or battery-powered.

    Uses of RFID Readers

    • Livestock tracking - location and ownership identification.
    • Retail - Price details stored on the tag, enabling automatic checkout with faster processing, multiple tags can be read simultaneously.
    • Admission passes - eliminates scanning or swiping for fast entry to theme parks, tracks location in the park, and stores information such as height or age for safety restrictions.
    • Libraries - automatic book tracking in and out, eliminating barcode scanning.

    Disadvantages of RFID Readers

    • Tag collision - signals from multiple tags can overlap and interfere with each other.
    • Radio waves are easily jammed or interrupted.
    • Data transmitted by the tag is easily hacked.
    • More expensive than comparable barcode systems.

    Optical Mark Recognition/Reader (OMR)

    • Reads marks written in pen or pencil on a form.

    Uses of OMR Devices

    • Reading questionnaires, multiple-choice exams, voting papers, and other forms with marked responses.

    Advantages of OMR Devices

    • Fast and automatic input of survey results.
    • More accurate than manual data entry.
    • More accurate than OCR methods.

    Disadvantages of OMR Devices

    • Forms require precise mark/shading placement for accurate information.
    • Incorrectly filled forms may cause inaccuracies and require manual verification.

    Optical Character Recognition (OCR)

    • Converts printed text on documents into electronic form.
    • OCR software then transforms the electronic data into usable formats for applications like word processors and presentation software.

    Uses of OCR

    • Processing passports and identity cards.
    • Converting hard copy documents into digital form.
    • Automatic number plate recognition in car parks.
    • Digitizing historical newspapers and rare books for archival and research purposes.

    Barcode Readers

    • Read information encoded in barcodes.
    • Often built into POS terminals in supermarkets.
    • Handheld scanners or wands are used for barcodes on large or immobile items.

    Uses of Barcode Systems

    • Supermarkets and other shops for automatic stock control, itemized billing, and product information.
    • Libraries for tracking loaned books.
    • Safety function in companies for regular equipment checks.

    Advantages of Barcode Systems

    • Faster than manual data entry with fewer errors.
    • Improved safety by enabling automatic testing records of components.
    • Allows automatic stock control.
    • Well-established and reliable technology.

    Disadvantages of Barcode Systems

    • Relatively expensive to administer.
    • Not foolproof, barcodes can be switched.
    • More vulnerable to damage than RFID tags or magnetic stripes.

    Quick Response (QR) Code Scanners/Readers

    • QR codes are made up of filled-in dark squares on a light background.

    Uses of QR Codes

    • Advertising - Contain business addresses, phone numbers, email, and website addresses, the smartphone screen displays the information, or automatically opens the linked website.
    • Boarding passes - Automatically sent to a phone or tablet.

    Advantages of QR Codes

    • Higher data capacity than normal barcodes.
    • Reduced errors due to built-in error-checking.
    • Easy transmission via text messages or images.

    Disadvantages of QR Codes

    • Multiple QR code formats exist.
    • Malicious code can be embedded (attagging) to gain access to the user's device, redirect them to fake websites, or download viruses.
