How to scan a product barcode to look it up
The striped barcode on a product is a UPC or EAN number that identifies the item. Scanning it with your phone turns those stripes into a number you can search, copy, or check against a retailer.
Scan and look up
- Open Scan QR Code Master and point the camera at the barcode.
- Keep the stripes horizontal and in frame until it reads.
- Copy the number, or search the web for it to find the product and prices.
- The scan is saved in History if you want to check it again later.
Tips for a clean barcode scan
- Good, even lighting helps — avoid glare on glossy packaging.
- Hold steady and fill the frame with the barcode.
- Flatten curved packaging as much as you can so the whole code is readable.
FAQ
- Can I compare prices by scanning a barcode?
- Scanning gives you the product's UPC/EAN number, which you can then search online or paste into a retailer's site to compare. Scan QR Code Master reads the barcode; the price lookup happens in your browser or a store's own app.
