Handheld scanners are store and office devices used to transfer documents or images onto a computer. Handheld scanners are portable, which comes in handy in a number of applications.
Handheld scanners can be used to scan documents, photographs and barcodes. The scanner takes an imprint of the item being scanned, converts it into an electronic format and sends the electronic document to the user's computer.
To scan a document using a handheld scanner, the user must hold the device in his or her hand and aim the scanning side at the item. The user activates the scanning operation by pressing "start" or "scan". Then, the user moves his or her hand over the item to be scanned.
Handheld scanners are programmed to communicate with the user's computer or laptop. In order for communication to take place, the computer or laptop must be set up with the right software to accommodate the communication.
Users must set the resolution of certain handheld scanners, which is measured in dots per inch (DPI). DPI settings control the quality of the electronic image that is produced. The higher the DPI, the higher the image quality.
A common type of handheld scanner is the barcode scanner, which is commonly found in retail stores. Handheld page scanners are scanning devices that can capture entire documents.
