Companion Barcode Scanners: Types, Uses and How to Choose
A companion barcode scanner is a small, pocket-sized device that scans barcodes and either stores the data or sends it to a phone, tablet or PC. It turns any mobile device into a fast data capture tool without the cost of a full mobile computer. This guide explains how companion scanners work, the main types, where they are used and how to choose one.
Key takeaways
- A companion scanner fits in the palm and scans with one button.
- Data is stored in the scanner (batch mode) or sent live over Bluetooth or USB.
- Laser, CCD and 2D imager models suit different barcodes and budgets.
- Common uses include inventory, asset checks, visitor registration and mobile point of sale.
What a companion scanner does
A companion scanner, sometimes called a data collector, pairs with a smartphone, tablet or computer. One press of the button scans a barcode. In live mode the data appears straight in the app on the paired device; in batch mode the scanner stores scans and uploads them later over Bluetooth or a USB cable.
Types of companion barcode scanners

| Type | Reads | Best for |
|---|---|---|
| Laser | 1D barcodes | Fast scanning of printed linear barcodes |
| Linear imager (CCD) | 1D barcodes | Low power, no moving parts, everyday use |
| 2D imager | 1D and 2D codes, including on screens | QR codes, mobile tickets, mixed labels |
Where companion scanners are used
- Inventory and stock counts in stores and small warehouses
- Asset checks for IT equipment, tools and furniture
- Visitor registration and access control by scanning ID or QR passes
- Mobile point of sale and line busting in retail
- Field service where technicians already carry a phone
For heavier daily use in warehouses or plants, a rugged mobile computer may be a better fit. See types of enterprise mobility solutions and our guide to Zebra mobile printers.
How to choose a companion scanner

- Check your barcodes. Choose a 2D imager if you need QR codes or codes on screens.
- Decide on connection. Bluetooth for phones and tablets, USB for PCs, batch mode where there is no device nearby.
- Check compatibility. Make sure it works with your phone, operating system and app.
- Consider durability and battery. Look at drop rating and scans per charge for your shift pattern.
