NFC business cards
The business card that never goes out of date
How HexaFlow designed, built and launched Nexus: an NFC card platform that runs a whole company's cards from one place, in five languages, across the UK, Europe and the Gulf.

The problem
Paper is out of date the day it's printed
People change roles and numbers, companies rebrand, and the old cards keep circulating. The details rarely reach anyone's phone, never mind a CRM, and nobody can tell which meetings turned into business.
NFC cards fix the obvious part: tap a card on a phone and a profile opens, with no app to install. The hard part is everything behind that tap.
For a professional
The profile has to look good, load instantly on any phone, save straight to contacts, and change the moment their job does.
For a company
Hundreds of cards have to stay on brand. Someone decides who can change what, and when a person leaves, their card and contacts stay with the company.
Every card already printed has to keep working. A link engraved into a metal card can't be reissued.
So every card points at a permanent address. Reassign it, offboard its owner or rebrand the company, and the card in someone's wallet still opens the right profile.Getting started
Free to start, with a card when you want one
Anyone can make a Nexus profile for free and share it by link or QR code. Every card comes with one, and the paid plans add templates, more profiles, analytics history and the tools teams need.
Pro to try, then a choice
Every new account gets 7 days of Pro, and activating a card gives 14 days from that day. When a trial ends, the owner chooses which profile stays live, and nothing hidden is deleted for 30 days.
Sign in with Google, carry it in Wallet
Sign in with Google alongside email, passkeys and company single sign-on. A Google Wallet pass carries the profile's QR code and updates itself whenever the profile changes.
Reports that actAnyone can report a profile from its page. When several different people report a free profile, it goes offline until it's reviewed, and its owner is told why.
Sign-up limitsEmail addresses are verified and sign-ups are limited per network each day, which keeps spam accounts out.
Out of search at firstNew free profiles stay out of search results for their first three weeks, and accounts unused for a year are put to sleep after an email notice.
The editor
Every colour, corner and typeface is a setting
Profiles are built from blocks: links, socials, text, images, video, files and lead forms. Every style starts at the template's value and can be changed, then restored with one click. The piece we're proudest of is automatic contrast: pick any button colour and Nexus picks text that stays readable, using a very dark or very light shade of the same hue.

The cards
PVC, wood and metal, etched to order
Eleven finishes across three materials, each with an NFC chip and a QR code that open the same live profile. PVC is printed in full colour, wood is laser-engraved, and metal can carry fine etched patterns across the whole card. Each card is a one-off purchase, delivered in 3–5 working days in the UK.

The company console
Where a card becomes a system
Companies invite staff one by one or import a whole team from a spreadsheet, group them into departments, and decide how much freedom each person gets.
Owner
Everything, including billing.
Admin
The whole company.
Department manager
Their own department, with exactly the powers the company grants.
Employee
Their own profile and card.
Access rules
Start from a preset (company controls everything, shared, or employees manage their own), then set each part of a profile to one of three levels. Exceptions can be made for one person without touching anyone else.
Approvals
An edit that needs sign-off waits in a queue, side by side with what's live, until a manager approves it. Everyone is told in the app, and each person only ever sees their own notifications.
Company cards
Cards ordered for a company land in its pool, already registered. Admins hand them out, reassign them, block a lost one in seconds, and keep a full history of who held which card.
Offboarding
When someone leaves, their cards return to the pool and their profile is archived. The old link forwards to a colleague or explains they've moved on, and every contact they collected stays with the company.
Analytics
Every tap, on a map
Nexus shows where profiles are opened, by card tap, QR scan or shared link, at city level, with filters by card and date. It tracks saves, exchanges and leads over time, and it does all of this without tracking cookies or storing a single IP address.
Analytics
Who tapped, where they were, and what they did next.

No tracking cookiesUnique visitors are counted once a day without a cookie, a promise a company's legal team can check.
Into the tools they useNew contacts flow into six native CRMs, Zapier and Make, or anything else through signed webhooks that pause themselves if the receiver keeps failing.
Integrations
One tap, and the lead is already in the pipeline
Every contact, form, booking and payment lands where the team already works: six CRMs connected natively, Zapier and Make for thousands more, and an API for the rest. No exports, no retyping after an event.

Meetings and payments
A Booking card for Calendly, Cal.com, HubSpot Meetings and Microsoft Bookings, and a Pay button for 13 providers, from Stripe and PayPal to Tap, Ziina and Thawani, paid straight to the holder.
AI that does the typing
Photograph a paper card in Arabic or English and it becomes a contact. Lead enrichment looks up company and role on the public web and shows its sources. Monthly credits on every paid plan.
An API for everything else
A public REST API with API keys and REST hooks, HMAC-signed webhooks that retry and pause themselves, and lead attribution that records the campaign each enquiry came from.
Enterprise identity
From first day to last, without a ticket
Single sign-on and SCIM are part of the Teams plan, not an enterprise upsell. The company's identity provider decides who has a card, and Nexus follows.
OktaMicrosoft Entra IDGoogle WorkspaceSAML 2.0 · OIDC · SCIM 2.0
- 01Joins
SCIM creates the account from Okta or Microsoft Entra ID.

Single sign-on with SAML or OpenID Connect; SSO or two-step can be required.

How we built it
One codebase, three faces, five markets
A single Next.js application sits behind a routing layer that decides which face each request gets and which language it's in, and applies security headers to every response.
nexustap.co
The website, in five languages, each at its own address.
app.nexustap.co
Sign-in, the dashboard, the company console and admin.
link.nexustap.co
Public profiles and card taps. Every printed link is permanent.
Built to pass a security review
Business cards carry personal data, and Nexus sells to companies with procurement teams.
- Field-level encryption (AES-256-GCM) of contact details and secrets, with keyed lookups on encrypted emails.
- Enterprise sign-in: single sign-on with SAML or OpenID Connect, SCIM directory sync that provisions and offboards people automatically, passkeys, and Sign in with Google.
- Two-step verification, breached-password checks and rate limiting on every sensitive action.
- Least privilege: every team rule lives in one place and is enforced on the server.
- Strict headers: a Content Security Policy, HSTS, and an audit log of administrative actions.
- EU hosting in Amsterdam: application, database and files, so European customers' data stays in Europe.
Reaching five markets
Found, and read, in every market Nexus sells to.
- English, Arabic, German, Spanish and French on separate URLs, so search engines index every version.
- Right to left for Arabic, and careful typography down to how long German words wrap on a small phone.
- A page for each market: the UK, Europe, the UAE, Oman and Saudi Arabia.
- Language offers, not redirects. Visitors are never forced away from the page they asked for.
