6.10 Recognition systems

What is the purpose of Optical Mark Recognition (OMR)?

• Detects marks on paper

• Converts printed or handwritten text into machine-readable text

• Uses radio frequency signals to transmit data stored on a microchip

• Enables short-range wireless communication between devices

Which of the following is a disadvantage of Optical Character Recognition (OCR)?

• Fast and efficient data collection

• Limited to predetermined responses

• Can struggle with different fonts or handwriting styles

• Limited read range

What is the main use of Radio Frequency Identification (RFID)?

• Detects marks on paper

• Converts printed or handwritten text into machine-readable text

• Uses radio frequency signals to transmit data stored on a microchip

• Enables short-range wireless communication between devices

Which of the following is an advantage of Near Field Communication (NFC)?

• Limited range

• Compatibility issues with some devices

• Convenient and secure

• Sensitive to poor marking or smudging

What is the main characteristic of Biometric Recognition?

• Highly secure, difficult to forge or replicate

• Limited to predetermined responses

• Sensitive to poor marking or smudging

• Limited read range

Why are biometric systems more effective than other methods of security?

• The biometric data is unique to the person

• The biometrics cannot be forgotten/stolen/shared like passwords

• The person needs to be present to enter the data

• Difficult to replicate/forge/fake/duplicate

How does RFID work?

• Detects marks on paper

• Converts printed or handwritten text into machine-readable text

• Uses radio frequency signals to transmit data stored on a microchip

• Enables short-range wireless communication between devices

What is the power source for passive RFID tags?

• Electromagnetic energy transmitted by the RFID reader

• Integrated circuit (IC) and an antenna

• Battery

• Radio waves

What is the main usage of Near Field Communication (NFC)?

• Tracking stock, passports, automobiles, contactless payment

• Payment using a smartphone

• School registers, multiple-choice examination papers, barcodes, QR codes

• Converts printed or handwritten text into machine-readable text

What is the security level of NFC?

• Highly secure, difficult to forge or replicate

• Limited to predetermined responses

• Sensitive to poor marking or smudging

• Limited read range
