Can't find the expiration date on a package? ExpiryFinder shows you exactly where to look. Expiration dates, best-before dates, use-by dates and production codes are often tiny, faded, or hidden in unexpected places. ExpiryFinder helps you find them quickly. HOW IT WORKS 1. Scan the product's barcode. 2. ExpiryFinder identifies the product and shows a photo of the packaging. 3. A marker highlights the exact spot where the date is printed, with a short tip such as "Check the bottom of the bottle" or "Look on the back, near the barcode." 4. Look at your own product and find the date yourself. FEATURES • Scan any barcode — EAN, UPC, Code128, QR and more • See where the date is printed, highlighted on a reference photo • Zoom and pan photos to read fine print clearly • Swipe through multiple photos contributed for the same product • Tips for common spots: bottle caps, crimped tube ends, lids, flaps and areas near the barcode • Works with expiration, best-before, use-by and manufacturing dates • Can't find a product?
