Quick answer

A barcode (UPC or EAN) is a one-dimensional code that stores a short product number, and it's what registers and price comparison apps use to identify the exact product. A QR code is a two-dimensional square that can store much more, usually a web link. To compare prices, scan the barcode.

Why barcodes are best for price comparison

A product barcode identifies the exact product (brand, item and size), and the same number is used at every store that sells it. That's what makes it perfect for comparing prices. More in what the numbers on a barcode mean.

What QR codes on packaging do

QR codes on products usually link to a website: recipes, ingredients, recycling information, promotions or registration. Some newer product codes combine product identification with a link, and the industry is gradually adding 2D codes to packaging. Today, the standard product barcode is still the most reliable way to identify a product for price comparison.

Be careful with QR codes in public places. A QR code can send you to any website. Check the web address before entering any personal or payment information.
