Distribution patterns that actually convert.

Four channels — QR, NFC, URL, email signature. Each has a job. Use the right one for the moment.

01The QR code — your everywhere asset

From your card's backend form view, click Download QR Code. You get a high-resolution PNG you can drop on:

  • Printed business cards (the original use case)
  • Conference badges and lanyards
  • Trade-show booth backdrops
  • Slide deck title pages and last-slide CTAs
  • Restaurant tabletops, retail signage, vehicle wraps

Print it big enough that someone two meters away can scan it. As a rule of thumb, the QR should be at least 1/10th the distance between the QR and the eye of the person scanning it.

The QR includes a small brand logo overlay by default. You can swap it for your own brand mark in the card's settings — see Setting Up Your Card.

02NFC for the in-person moment

NFC cards are the upgrade over QR for face-to-face. The other person taps your card to their phone, your URL opens — no camera, no app, no QR-scanning friction.

The full programming walkthrough lives in the NFC Card Programming guide. The short version: buy a writable NTAG215 card, install NFC Tools on your phone, write your card's URL, done.

03The URL — small, flexible, underrated

Your card has a normal web URL. Use it everywhere a link goes:

  • SMS / WhatsApp: "Here's my card: yoursite.com/jane-doe"
  • LinkedIn "Featured" section — pin it as a featured link
  • Instagram / TikTok bio — replace your linktree
  • Calendly intake page — link your card from "About me"
  • Slack / Notion profile — for distributed teams

04Drop it into your email signature

Vinc includes an email signature generator. From the backend, open your user record and use the signature builder to produce HTML you can paste into your email client's signature settings — the same flow whether you use Gmail, Outlook, Apple Mail, or anything else.

Email signatures are the most-used and most-undervalued distribution channel. Every email you send is a card share. Set this up once and forget it.
