UPC barcodes are one of the most commons codes that are being read daily around the world. If you’re not familiar with the UPC code you can find it on any commercial product from the grocery store to the everything on Amazon.

The UPC number itself is referred to as the GTIN (Global Trade Item Number). The GTIN is made up of two parts: The UPC Company Prefix and the number that you have assigned to that unique product. This information is how any business can recognize what each product is.

The UPC code is a standard 1D linear barcode so almost any device will be a suitable UPC barcode scanner. The primary concern when choosin g a scanner will be reading performance to keep up with your specific application.

Laser Scanners
By far the most common, laser scanners are more than capable of reading any UPC. These scanners often are the most cost effective solution but you will need to properly line up the red laser line with the UPC to get a good read. This usually isn’t a deal breaker but for higher volume applications you may want to look at other options. One of the most popular laser scanners today is the AirTrack S1.

Imagers
Imager-based scanners utilize a specialized camera to read a barcode as opposed to reflecting light like on a laser. This means you can capture barcodes without really aiming. Just get within the reading area of the imager and you can get a positive read. Upside down, sideways, it doesn’t matter. Imagers like the AirTrack S2 will improve scanning accuracy and speed for faster check-out lines and inventory check-ins.
