POS question
How does barcode scanning work in POS?
Short answer
Barcode scanning in POS uses a camera or handheld scanner to read the product's barcode (UPC/EAN). The app looks up the matching item in your catalog, adds it to the cart with the correct price, and completes the sale—much faster than typing names or prices manually.
More detail
When setting up, scan each product once to link barcodes to names and prices. Good lighting helps the camera read labels quickly.
Items without barcodes can still be searched by name in most POS apps.
