The short answer
Pick the method that fits the moment
Sharing a digital business card takes one gesture. In person, an NFC tap or a QR code is instant. Remotely, a share link, an email signature, or a social bio link does the job. However you share it, the other person lands on your smart profile in their browser and can save your contact in a single tap.

Seven ways to share your card
Tap with NFC
Hold your NFC card or Phone Tap card against the top of the other person’s phone — their profile link pops up to open, no app needed.
Show your QR code
Open your QR code on screen or print it anywhere. The other person points their camera at it and taps the link that appears.
Send your share link
Copy your profile URL and paste it into any message, text, or chat. One tap opens your full card in their browser.
Add an Apple Wallet pass
Keep your card as a Wallet pass with a built-in QR on your Lock Screen. Pull it up in a second — it works offline and updates itself.
Put it in your email signature
Add your profile link and QR image to your signature so every email you send becomes a one-tap way to save your details.
Add it to your home screen
Save your profile as an icon on your phone’s home screen. Open it and turn the screen toward someone to share your card in one tap.
Drop it in your social bio
Paste your profile link into your Instagram, LinkedIn, X, or TikTok bio so anyone who visits can open and save your full card.
Questions
Sharing FAQ
How do I share a digital business card?
Pick whichever of the seven methods suits the moment: hold your NFC card to the top of the other phone, show your QR code, send your share link by text or email, hand over an Apple or Google Wallet pass, put the link in your email signature, add the profile to your phone home screen, or drop it in your social bio. All seven open the same smart profile in the other person’s browser, and nobody needs an app.
How do I share my digital business card without meeting in person?
Copy your share link and paste it wherever the conversation is happening — a text message, an email, a LinkedIn message, a Zoom chat, or your email signature so it goes out with every message you send. The link is permanent, so one paste keeps working even after you change jobs or numbers.
What is the fastest way to share my digital business card?
An NFC tap is fastest when you are face to face — just hold your card to the top of the other phone. When you are remote, sending your share link takes one paste.
Does the person I share with need an app?
No. Every method opens your profile in their normal phone browser. There is nothing for them to download or install — they just tap, scan, or click.
What if their phone does not support NFC?
Show your QR code or send your share link instead — both work on any smartphone. That is why every profile ships with a QR, a link, and a Wallet pass alongside the NFC tap.
