NFC card platform

A full-stack digital business card platform built around shareable online profiles and NFC cards. Users create and customize a digital identity, publish it to a unique URL, generate a QR code, and connect that profile to an NFC card. I built the profile builder, live preview, public profile, analytics, authentication, payments, admin platform, and the backend behind the whole system.

A complete full-stack NFC and digital identity platform that lets users create, customize, publish, share, and measure a dynamic digital business card.

The product

A business card that can keep changing.

This platform turns a physical NFC card into a dynamic digital identity. Users create their profile online, customize how it looks, and connect it to a shareable URL that can be opened through NFC, QR, or a direct link.

The idea

The card is physical. The identity doesn't have to be.

Traditional business cards become outdated as soon as someone's role, phone number, company, or links change. By putting the profile behind a persistent URL, the physical card can stay the same while the digital identity continues to evolve.

The builder

Build it the way you want.

The profile builder gives users control over their information, sections, links, colors, layouts, branding, and other visual details, with a live preview showing how the finished profile will look.

NFC

One tap to share everything.

The NFC card acts as the physical entry point. A tap opens the user's profile URL, where the visitor can access contact details, social profiles, websites, and other information.

Dynamic identity

Update the profile. Keep the card.

The NFC card points to the profile rather than containing the profile itself. That means the owner can change their information or design later without needing to replace the physical card.

Public profile

A digital card that behaves more like a mini-site.

The public experience brings together contact actions, social links, websites, location information, and other profile content in a mobile-friendly interface designed for quick interaction.

Sharing

NFC isn't the only way in.

Every profile can also be reached through its direct URL and generated QR code, giving users multiple ways to share the same digital identity.

Analytics

Know what happens after the tap.

Unlike a traditional paper card, the digital profile can provide insight into profile activity and interactions, giving owners a better understanding of how their identity is being used.

Under the hood

A complete platform behind a simple tap.

The product connects a flexible profile builder, backend APIs, profile data, public rendering, analytics, NFC, QR sharing, authentication, payments, and administration into one system.

Features

  • Digital profile builder

    Users create a complete digital identity with contact information, professional details, social profiles, links, and other profile content.

  • Flexible profile customization

    Themes, colors, layouts, typography, buttons, backgrounds, and branding let users personalize how the public card looks.

  • Live preview

    Profile changes can be previewed while editing so users see how the public card will look before publishing.

  • Custom sections

    Profiles are composed from content sections and blocks, so a card can fit individual or business needs.

  • Unique profile URL

    Every published profile gets a unique shareable URL that works independently of the physical NFC card.

  • NFC card integration

    The profile URL connects to an NFC card, so someone can open the digital profile by tapping the card with a compatible phone.

  • Dynamic NFC destination

    The card points to the profile URL rather than storing the profile itself, so the identity can change without replacing or reprogramming the card.

  • QR code sharing

    Generated QR codes give the same profile a second physical and digital sharing method.

  • Contact actions

    Visitors can tap through to phone, email, WhatsApp, website, social, location, and other available contact actions.
