QR Code Scanner
To compare prices in a store, scan the product's barcode with a price checker app. The app identifies the exact item and lists live prices from major retailers — Amazon, eBay, Best Buy, Target, Farfetch, StockX — so you can see in seconds whether the shelf price is a deal or a markup.
That "SALE" tag means nothing until you know what the same product costs elsewhere. Retail prices for identical items routinely differ by 10–30% between stores and marketplaces. A barcode scan is the fastest possible way to check — faster than typing the product name into three shopping apps while standing in the aisle.
Check any price in 3 steps
- Open the scanner in the QR Code Scanner ＊ Barcode Reader app.
- Scan the barcode on the box or tag — UPC, EAN and ISBN codes are detected automatically.
- Compare the list. The app shows the product with current prices across retailers, cheapest highlighted. Tap any listing to view it.
Where a scan-to-compare habit saves real money
- Electronics: big-box shelf prices often trail online prices by weeks. Scan before you carry it to the register.
- Fashion & sneakers: with StockX and Farfetch in the list, you see resale and boutique prices next to retail.
- Books: scan the ISBN — new, used and marketplace prices differ enormously.
- Gifts & toys: seasonal markups are invisible until you compare.
- Second-hand shopping: at thrift stores and garage sales, a scan tells you what an item actually resells for.
More than prices
The same scan can tell you more than what a product costs. For groceries, the app shows Nutri-Score and ingredient quality; for shampoo and skincare, it flags risky cosmetic ingredients. One scanner, three kinds of buying decisions.

Frequently asked questions
Which barcodes work for price comparison?
Standard retail barcodes: UPC (North America), EAN (Europe and most of the world) and ISBN (books). These uniquely identify a product so the app can match it across retailer catalogs.
Do I need an account to check prices?
No. Open the app, scan, and the price list appears — no registration, no ads in the way.
Why do prices differ so much between retailers?
Retailers price independently based on inventory, demand and promotions, and marketplaces add seller competition. Differences of 10–30% on identical items are common — which is exactly why the scan pays off.
