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.

Our house style: deep graphite with a copper accent.
Same two people, same content, 22 templates. Each one is a complete look: colours, typefaces, button shapes and layout. Pick one to hold it.
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.
The profile has to look good, load instantly on any phone, save straight to contacts, and change the moment their job does.
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.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.

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.
Everything, including billing.
The whole company.
Their own department, with exactly the powers the company grants.
Their own profile and card.
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.
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.
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.
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.
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.
Who tapped, where they were, and what they did next.
