Start from your payment service provider dashboard—most expose a downloadable QR or a payment URL you can encode.
In our editor, paste the URL, pick error correction H if you add a logo, and export PNG at 2–3× your final print width for sharpness.
Print a test sheet on the actual material (matte preferred). Scan with two Android phones and one iPhone from 25–40 cm.
Roll out only after a successful test batch—reprints are expensive at scale.
