How a QR code product passport works
Every published product in DPPC gets its own passport page at a permanent address and a QR code that leads to it. A customer, retailer, service technician or inspector scans the code with a phone and sees the product data straight away, without logging in. The address does not change when the data is updated, so a code printed on a label or in a manual stays valid, and the page always shows the current product data.
