Scan a QR code safely
Most modern phones open links from the camera app. When you want a dedicated scanning surface — or a second check on a suspicious print — use the free scanner on QRcode Global.
Open the scanner: it runs in the browser and helps you read codes without installing a random app from a poster.
Before you trust the destination
Read the URL preview when the OS shows it. Prefer https sites you recognise. Be careful with codes that promise prizes on street poles or in unsolicited email.
On this generator site you create codes; on the scanner you read them. Keeping create and scan as clear actions reduces mistakes.
When a code will not read
Clean the lens, improve lighting, move closer and make sure the whole square is visible. Wrinkled paper and curved bottles need a flatter angle or a larger reprint.
