How we verify this guide
Before this page is included in the public guide directory, its examples are compared with the payload produced by the linked QRFlow generator and with the export and scan-readiness controls available in the current build. Camera, lighting, paper, print size, and destination apps can still change the result, so important print runs should always be tested on the final material and real devices.

First scan the exported QR on a screen. If the screen version works but the printed card does not, the problem is usually print size, quiet zone, contrast, glare, or blur. If the screen version also fails, simplify the vCard or remove styling before you reprint.
30-second diagnosis # Open the original SVG or PNG at full size and scan it from another screen. Scan the printed card in bright, diffuse light with glare tilted away from the camera. Try one iPhone and one Android from roughly 15–30 cm away. If only the print fails, compare the final measured QR size and blank border with the exported file. 8 causes and the fix for each # Too small : use 20–25 mm for most cards; use 25–30 mm for a dense vCard or weaker print quality.Quiet zone cropped : keep a blank border of at least four QR modules on all sides.Low contrast : use a dark code on a light, solid background; avoid gradients and transparent overlays.Gloss or glare : move the QR away from spot UV, foil, holographic stock, folds, and curved surfaces.Blurred export : print from SVG when possible; do not enlarge a screenshot or compressed preview.Dense vCard : remove notes, extra URLs, secondary phone numbers, and other nonessential fields.Heavy styling : remove the logo or decorative modules, then retest the plain QR before adding styling back.Print damage : check for scratches, ink spread, trimming, a border touching the code, or a fold through the modules.Test before ordering another batch # Digital file : scan the original export on a second screen.
Office proof : print at actual size on matte paper and verify the QR measures at least 20 mm.
Final stock proof : test the real paper, coating, colors, and finish under indoor and daylight conditions.
Device check : test iPhone and Android, then scan from both 15 cm and 30 cm.
Check the file with the QR scanner , confirm print dimensions with the QR size calculator , review the business card size guide , and verify the quiet zone rule . If the payload itself is too dense, rebuild a minimal vCard in the business card QR generator .

Quick answers Common questions Why does my QR code scan on screen but not on the business card? The printed version is probably too small, blurred, cropped, low contrast, or affected by glare. Measure the final QR and test a matte proof.
How large should the QR code be on a business card? Use 20-25 mm for most cards and increase to 25-30 mm when the vCard is dense or print quality is limited.
Can glossy business cards stop a QR code from scanning? Yes. Reflections can hide modules from the camera, especially under direct light. Use matte stock or keep the QR away from glossy and foil finishes.
Should I use PNG or SVG for a printed business card QR? Use SVG for print because it stays sharp at the final size. Avoid screenshots and enlarged low-resolution PNG files.
