A QR code business card that saves your contact in one scan

A QR code business card is any business card, paper or digital, that carries a QR code linking to your contact details. The best version links to a full digital business card, so a single scan shows your photo, title, company and links and lets the person save you to their phone.

Two ways a QR code can hold your contact

• A link to your digital card. The code holds a short web address such as carddeck.co/yourname. Scanning opens a mobile page with buttons to call, email, message and save the contact. You can update the page at any time.
• A vCard inside the code. The code holds the contact data itself. Scanning offers to save the contact directly, but there is no page, no links, no photo in most cases, and nothing can be changed after printing.

CardDeck supports both. For most people the first option is better: the code stays small and simple, the card can be updated, and you can see how often it is scanned. If you specifically want a code that works with no internet connection on the scanning phone, use a vCard QR code instead.

Where QR business cards are used

• The back of a printed paper business card
• Name badges and lanyards at events
• The last slide of a presentation or webinar
• Reception desks, shop counters and service vans
• Email signatures and video-call backgrounds

QR codes were invented by Denso Wave in 1994 and are standardized as ISO/IEC 18004. Every modern iPhone and Android phone reads them from the built-in camera app, which is why they have become the default bridge from print to phone.

To make a QR code business card, create a digital card, generate its QR code, add the code to your print design and test-scan the result. With CardDeck it takes about ten minutes before printing.

1. Create your [digital business card](/digital-business-card). Add your photo, name, title, company, phone, email and one call-to-action button.
2. Publish it. You get a permanent link and a QR code for that link.
3. Choose static or dynamic. For anything you print in quantity, choose dynamic so you can change the destination later.
4. Style the code. Apply brand colors and an optional center logo. Keep the code dark on a light background; CardDeck warns you if contrast is too low.
5. Export. Download SVG for print (vector, sharp at any size) or PNG for screens.
6. Place it on your design. Put the code on the back of your card or in a clear corner of the front, with a short label.
7. Proof and test. Print one sheet at actual size, scan it with at least one iPhone and one Android phone, and check that the save-contact button imports your details correctly.
8. Order your print run. Because the code opens a page you control, a smaller run is usually enough.

Already have paper cards?

You do not have to throw them away. Print the QR code on small stickers for the back of existing cards, or use it on your badge and phone screen until your next order.

Print the QR code at least 2 × 2 cm (about 0.8 × 0.8 in) on a business card, with a blank margin around it. That is large enough for any modern phone to scan from a normal hand-held distance.

Size rules of thumb

• Hand-held cards: 2–2.5 cm square is comfortable for scanning at 15–25 cm.
• Badges and lanyards: 2.5–3 cm, because people scan from a little further away.
• Posters and signs: make the code about one-tenth of the scanning distance, so roughly 10 cm for a poster read from one metre.

The quiet zone

QR codes need a clear margin, called the quiet zone, around all four sides. The ISO/IEC 18004 standard specifies four modules (four of the small squares) wide. Do not let text, borders or card edges intrude into it.

Contrast and color

• Use a dark code on a light background. Inverted codes (light on dark) fail on some scanners.
• Brand colors are fine if contrast stays high; very light yellows, pastels and gradients often fail.
• Avoid printing over busy photos or textures.

Logos and error correction

QR codes include error correction at four levels: L, M, Q and H, which recover roughly 7%, 15%, 25% and 30% of damaged data. A center logo works because it uses some of that capacity. Keep the logo under about 20% of the code's area, and leave CardDeck's error correction setting at its default when you add one.

File format for print

Export SVG whenever possible. If your printer needs a bitmap, export PNG at 300 dpi or more at the final printed size.

Use a dynamic QR code on printed business cards. It contains a short link you can re-target, so a change of job, phone number or company does not make your printed cards useless.

What each type stores

• A static QR code stores the data itself, such as your card's link or a vCard. It works forever and depends on no service, but it can never be edited.
• A dynamic QR code stores a short redirect link. When scanned, it forwards to the destination you set in CardDeck. You can change that destination at any time and see scan counts.

Why dynamic suits business cards

• People change jobs and numbers. With a dynamic code, you point the same printed code at your new card.
• You can measure the print run. Scan counts show whether your paper cards are being used at all.
• Shorter data means a simpler code. A short redirect link produces a less dense pattern, which scans faster at small sizes.

When static is fine

If your QR code points to your permanent CardDeck card link, a static code works well too, because you edit the card itself rather than the code. Static codes are unlimited on every plan. Dynamic codes are limited by plan: 2 on Free, 50 on Pro, 200 on Team and unlimited on Business.

For the full comparison, read static vs dynamic QR codes, or see how dynamic QR codes are edited and tracked.

Put the QR code where it can be scanned without covering anything important: usually the back of the card, centered or in the lower right, with a short label. On a one-sided card, use a corner with a clear margin.

Layout tips

• Back of the card: the most common choice. The front keeps your name and logo clean; the back holds a large, easy code.
• Front corner: works on minimal designs. Keep at least 3 mm from the trimmed edge so the cutter cannot clip the quiet zone.
• Avoid folds, foils and embossing over the code; they distort the pattern.

Tell people what the code does

A label increases scans because people know what they will get. Good examples:

• "Scan to save my contact"
• "Scan for my portfolio and booking link"
• "Scan to message me on WhatsApp"

Keep the rest readable

Your name, title and one contact method should still be printed in text. Some people will not scan, and a card that is only a QR code looks unfinished.

Print specs to give your printer

• Final size and bleed (commonly 3 mm or 1/8 in on each edge)
• QR code supplied as vector SVG or PDF, not a screenshot
• Code printed in a single solid color, ideally black or a dark brand color
• Matte or uncoated stock if possible; high-gloss finishes can cause glare under bright lights

A QR code business card can work in both directions: the visitor saves your contact, and with contact exchange turned on, they can share theirs with you in the same visit.

What the visitor sees

1. They scan your code and your card opens in their browser.
2. They tap Save contact and your vCard imports into their phone.
3. They see an optional Share your details form and can leave their name, email, phone and company.

Nothing is collected unless they fill in the form. The form records consent and a timestamp with each contact.

What you see

• New contacts appear in CardDeck with their source, for example the specific QR code or card that brought them in.
• You can add tags and notes right after the conversation.
• Export to CSV or vCard; on Team plans, export to your CRM.

Contact management explains tagging, ownership and export in detail. Captured contact limits are 50 on Free, 1,000 on Pro, 5,000 on Team and unlimited on Business.

Measuring a print run

With a dynamic code, every scan is counted. If you print separate codes for different events or mailings, you can compare which one gets scanned. Analytics are aggregated: counts, dates, device type and approximate region.

Most QR business card failures come from printing problems rather than the code itself: too small, too little contrast, or never tested. A two-minute test on a printed proof prevents almost all of them.

Checklist before you print

• Size: at least 2 × 2 cm.
• Quiet zone: a clear border four modules wide on every side.
• Contrast: dark code on a light background, no gradients through the code.
• Logo: under about 20% of the code area.
• Destination: opens your digital card, not a generic home page.
• Dynamic: chosen for anything printed in quantity.
• Label: tells people what the code does.
• Test: scanned from a printed proof on iPhone and Android, in normal indoor light.

Mistakes that cost a reprint

• Pasting a QR code screenshot into a design, so it prints blurry.
• Linking the code to a page that needs a login or is not mobile-friendly.
• Using another service's short link that later expires or shows ads.
• Placing the code over a fold line, foil or textured finish.
• Encoding a long vCard directly, which produces a dense code that struggles at small sizes.

Is paper still worth it?

For many people, a small run of QR business cards plus a digital card on their phone is the right balance. For a cost and impact comparison, see paper vs digital business cards.
