Tawara school uses an optical mark recognition (OMR) system for its school register. An example of the register is shown. For each session of the school there are two lozenges to be shaded in. At the start of the registration period the teacher shades in a lozenge on the register to show that a pupil is present and shades in a lozenge for each pupil who is absent. If a pupil is late then the teacher shades in both the and the lozenges. The register sheets are sent to the school office to be processed and the data from them is stored in the computer’s database. Describe the inputs and computer processing of the registers when they are sent to the school office, prior to them being stored on the computer’s database. 1 10 The headteacher of the school is considering modernising the registration system so that pupils can register using a facial recognition system. Discuss the advantages and disadvantages of using a facial recognition registration system rather than the OMR system they currently use. [ 1 10 Biometric data, like facial recognition, is an example of personal data. Give two other examples of personal data that could be stored on the school registration database. 1 10

A school is going to introduce an automatic registration system controlled by computer. Students will carry a card which will be read automatically by an input device every session so that the school office will know that they are present. Name a suitable input device to read the card. Instead of using this system the school ICT teacher suggests using student fingerprints. Describe two advantages and two disadvantages of such a system. Advantage 1 Advantage 2 Disadvantage 1 Disadvantage 2

A ferry connects two countries. When car drivers approach the ferry they have to check in to confirm the details they have already booked. If they drive in to the self check-in lane, details of the car are automatically input to a computer. The terminal which is used for the driver to identify themselves produces a personalised welcome message on a screen. There is a database which contains details of the driver and the car. Write down the data which is automatically input to the computer. Other than your answer to give two items of data stored in the computer database. Explain how Optical Character Recognition is used before the computer processes the data. Explain the computer processing which takes place to produce the personalised message. 1 17
