A barcode scanner is one of the highest-value, lowest-cost upgrades a retail store can make. This guide covers how barcode pos software and scanner hardware work together, and how to choose the right setup for your store.
How barcode scanning works with your POS
Most modern scanners connect over USB or Bluetooth and act like a keyboard: scanning a barcode « types » the product code into the search field of your point of sale application, which then looks up the matching product automatically. This means most scanners work with compatible POS software without any special drivers.
Choosing between USB and Bluetooth scanners
- USB scanners are simpler to set up, don’t need charging, and are the most reliable option for a fixed checkout counter.
- Bluetooth scanners give cashiers freedom of movement — useful for larger stores, warehouses, or curbside checkout — at the cost of needing to keep them charged.
1D vs 2D scanners
1D (laser) scanners read standard linear barcodes found on most packaged retail products. 2D (imager) scanners read those plus QR codes, making them a better long-term choice if you plan to use QR-based loyalty programs, digital coupons, or supplier labels.
Getting started
Once your scanner is connected, no manual configuration is usually required — plug it in, open your POS application’s cashier screen, and scan a product to test it. See our features page for the full list of supported barcode scanners, receipt printers, and cash drawers.
