A QR service card that works well is not complicated to design - but there are a few rules that separate a card people actually scan from one that gets ignored. Most problems come down to the QR code being too small, the contrast being too low, or the card trying to say too much at once.
These tips apply whether you are printing a counter stand, a wall sign, or a business card. Get these basics right and your card will do its job every time.
Section 01QR code size and quality
The QR code is the most important element on the card. If it does not scan reliably, nothing else matters. For a counter stand or table card, print the QR code at a minimum of 5 cm by 5 cm - anything smaller and older phones or low-light environments will struggle. On a wall sign viewed from further away, go larger.
Always export your QR code as a high-resolution image - at least 1000 pixels by 1000 pixels. A blurry or pixelated QR code will not scan at all. We generate QR codes at print quality by default, so you can scale them up without losing clarity.
The minimum size for a counter QR code is 5 cm x 5 cm. Smaller than that and you will lose scans, especially from customers with older phones or in dim lighting.
Section 02Contrast and color
QR codes scan best when there is strong contrast between the code and its background. Dark code on a light background is the standard - dark brown or black QR on white or cream scans reliably across all devices. Avoid printing the QR code in light gray, yellow, or any color that blends into the background.
Never place the QR code over a photo, pattern, or gradient. Even small interference in the background can cause scan failures. Give the code a clean white or solid-color area around it, with a margin of at least half a centimeter on all sides.
Section 03What to include
The card works best when it carries one clear message. For a service card, that is: your business name, the QR code with a short instruction ("Scan to see our services"), and your WhatsApp number for customers who prefer to call. Everything else is secondary.
Keep text minimal. A customer glancing at the card while waiting should understand what to do in under three seconds. List your top three services if you must - but a long paragraph of text next to a QR code gets ignored. Save the detail for what customers see after they scan.
Section 04Adding your logo
Your logo should be above or beside the QR code, not overlaid on top of it. A logo centered in the middle of a QR code can interfere with scanning - QR codes have some built-in error correction, but a large logo in the center pushes past that margin.
Use a high-resolution version of your logo. A pixelated logo makes the whole card look unprofessional. If you only have a small version, ask your designer for the original file, or we can help you create a clean logo-matched card from scratch.
Section 05Test before you print
Before sending anything to print, test the QR code on at least two phones - one iPhone and one Android. Scan in normal lighting, then in dim lighting. If it fails in dim light, increase the code size or improve the contrast. It is far cheaper to fix the design file than to reprint 50 counter stands.
Also check what the customer sees after scanning. Make sure the link works, the page loads fast on mobile, and all your contact details are correct. A QR code that scans perfectly but lands on a broken page is worse than no QR code at all.
Test on two phones. Check the scan works, the link opens, and the page loads fast on mobile. One minute of testing saves a full reprint job.
