NFC vs QR business cards: which should you use?
NFC and QR are two ways to open a digital business card. Choose for the way you meet people: NFC for presenting a physical card in person, QR for a visible code, and a direct link for online conversations. Adaivo’s NFC card and QR code open the same approved online card.
What changes when you choose NFC?
An NFC card contains a chip that lets a compatible phone read the card’s link at close range. You need the actual physical card for that interaction. Pressing a button on a website cannot demonstrate whether your phone reads that chip.
With Adaivo, Digital only gives you a hosted card to share by link or QR. Digital + NFC adds a custom-printed physical card. The NFC chip opens the online card; it does not hold a separate contact list that automatically appears in the recipient’s address book.
When QR or a link is the better starting point
If most introductions happen through email or messages, a direct link is often all you need. If you want someone to open the card from a screen or printed material, a QR code gives them a visible target. A physical NFC card is optional for both uses.
Keep a link or QR available even when you use NFC. A recipient may have a phone that cannot read NFC links, or device settings and antenna position may prevent a successful tap. Opening the online card requires an internet connection; no Adaivo app or account is needed to view a public card.
Three ways to open the same online card
| Method | What the recipient needs | A useful moment |
|---|---|---|
| NFC tap | A physical NFC card and a phone that can read NFC links. | A face-to-face introduction where you can present your card. |
| QR scan | A visible QR code and a phone with a camera or QR reader. | A meeting, event or printed material where the code is easy to scan. |
| Direct link | The card’s URL and a web browser. | An email, message or online meeting where a clickable link is convenient. |

Fictional design preview
Open the interactive sample on this device, or scan this QR code with another phone. No account is needed to view it.
Open the interactive sample
This preview uses the Adaivo card renderer. Open the sample to change its design, share it or download the fictional contact.
- Compare the design.
Under Layout, choose a different layout. Under Theme, choose another colour. Look at the name, introduction and contact area as the card changes. These choices only affect your current preview.
- Open Share.
Select Share below the sample card. Scan the QR with another phone, or use Copy Link and open that link in another tab. The shared sample starts with its original design; your layout and theme choices are not included.
- Try Save Contact.
Close the share panel and select Save Contact. Open the downloaded vCard in a compatible contacts app and inspect it before confirming an import. It is labelled as a fictional sample and contains no phone number or email.
The sample’s contact buttons are disabled. It does not test a physical NFC chip. Sample choices do not carry into your own card: sign in to create and preview your design. Publication requires a purchase and Adaivo review.
Enable JavaScript in the sample to change its design and open Share. The sample card and contact download remain available without it.
Check the QR and contact download yourself
Use the sample above to check each result. These checks cover the web link and vCard, not a physical NFC chip.
The QR destination
The QR and the sample button open this same address:
https://card.adaivo.ai/demoThe page you should see
Look for Maya Sethi and the fictional-sample label. No sign-in is needed. Change a layout or theme, then open Share: its link starts the sample in the original design, rather than preserving your preview choices.
The contact you should download
Choose Save Contact in the sample and inspect the vCard before importing it. The name includes Maya Sethi and a fictional-sample label. The file has the sample website link, with no phone number or email. Downloading the file does not automatically add it to your contacts.
Check a physical NFC card in person
Once you have a physical card, test it with the phones you expect people to use. Follow the phone maker’s guidance for reading NFC links and where to place the card near the antenna. Open the detected link and check that the intended approved card appears.
If the tap does not work, try the QR or direct link. If those open the card, you have checked the online destination, but you have not proved the NFC chip and phone work together. If neither opens, check the internet connection and the link. The sample above only demonstrates the web and QR paths.
Opening a card is different from saving a contact
A tap or scan opens the card in a browser. The recipient then chooses Save Contact, opens the downloaded vCard in a compatible contacts app and confirms the import. Contact photo display and merging depend on that app.
A saved contact is a snapshot. Later approved edits appear at the same online card address, but they do not automatically update another person’s address book or text already printed on a physical card.
