Question 1 Report
Viren runs a mobile bicycle-repair service. He uses a rugged laptop in his van to create invoices and update customer information after each repair. Some customers ask to sign that the repair has been completed. Viren often works outside in bright daylight and cannot rely on an internet connection. He needs to choose suitable input and output devices that can be used quickly in a confined space.
(a) Give two input devices Viren could use to enter a customer's name and repair details. [2]
(b) Describe one advantage of using a stylus and touchscreen for capturing a customer's signature. [2]
(c) Explain why saving the completed invoice as a PDF file as well as printing it can be useful. [4]
Answer Details
(a) Two suitable input devices are a keyboard and touchscreen. A stylus, microphone, camera or barcode/QR-code scanner could also be used. [2]
(b) A stylus and touchscreen let the customer write directly on the screen in a similar way to signing paper. The signature is captured as digital data and stored with the invoice, so no separate paper signature form is needed. [2]
(c) A PDF can be stored on the laptop even without internet access and later emailed or shared when a connection is available. It provides a backup if a paper copy is lost and preserves the document layout across devices. It can also be searched or retrieved during a dispute, while printing supplies an immediate hard copy for a customer who requests one. [4]
