Final answer:
A handheld scanner is used in sports events to capture bar codes on tickets. The scanning action is considered computer technology.
Step-by-step explanation:
Tickets that are collected at sporting events have their bar codes scanned using a portable scanner. The process of scanning is regarded as computer technology. Barcodes are read by handheld scanners via optical technology. The barcode is illuminated by a light source, and light reflections are detected by a photosensor. The scanner then decodes and processes the collected data to produce the required information. This technology is a crucial component of contemporary technology since it is widely employed in many different applications, including retail, inventory management, and ticketing systems.
