The Scanfob® 4000 is a Bluetooth barcode scanner is a CCD barcode reader. CCD (Charged Coupling Device) barcode scanners use an imaging engine to take a picture of the barcode and then decode the characters. CCD barcode scanners are "linear imagers" meaning that you will still see a red focus line when triggering the scan.
Durable: CCD scanners have no internal moving parts so they are typically a bit more durable than a laser scanner.
More economical: CCD scanners, on average, are usually less costly than other barcode scanners.
Scan In Direct Sunlight & On Device Screens: Essentially, a CCD scanner is "taking a picture" of the barcode. Due to this scanning process, CCD scanners are able to operate in bright sunlight. Most CCD scanners are also able to read scans off a computer or other devices screens.
CCD engine enables barcodes to be read from PC and smartphone screens easily
