Scanning jobs require you to use a device to automatically input information into a computer system, thereby saving time over manual data entry. Some types of scanners are handheld, while others are flatbed scanners and not portable. Scanning jobs exist in retail, medical, and warehouse inventory fields, just to name a few. You could be a checkout clerk working with a conveyor belt scanner to ring up customers’ items. Alternatively, you could be a document scanner, responsible for scanning and printing documents in a variety of industries.
