The Opticon OPN 2002 is one of Opticon's smallest barcode scanners, measuring just 1.3"x2.5", and weighing only an ounce. Designed for mobility, this pocket memory scanner makes barcode data collection simple for anyone. It can be worn around the neck as a lanyard making data collection fast with Opticon's 100/scan per second laser. Using the OPN 2002 is straightforward with its two button function. Scan a barcode with the large button and it will be stored automatically. If you make a mistake, the smaller button allows you to re-scan the barcode in order to remove the item from the memory. It features 1 MB memory, enough to accommodate over 20,000 scans with timestamps.
