Identify and track items tagged with the most common barcodes. These scanners don’t require any software to communicate with your computer. When you press the trigger to scan a barcode, the data appears wherever your cursor is, just like when you type.

All scanners read 1D barcodes, such as UPC, EAN, Code 39, Code 128, and ISBN codes. Those that scan 2D barcodes read QR, Data Matrix, and PDF417 codes. Scanners for GTINs (Global Trade Item Numbers) read codes that are typically embedded in UPC and EAN barcodes.

Laser scanners work well for reading barcodes on rounded surfaces. CCD (charge-coupled device) scanners read barcodes on screens and other shiny surfaces better than laser scanners. They also have fewer moving parts than laser scanners, so they last longer. Image scanners read lower-quality barcodes than laser and CCD scanners. They’re also able to read barcodes on screens.

Scanners with a USB connection send data faster than Bluetooth scanners but require you to be tethered to your computer. Scanners with a Bluetooth connection work wirelessly hundreds of feet away from the computer they’re sending data to.

Scanners that cannot be sold to the listed areas are restricted due to energy efficiency and/or export regulations.
