For architects

The project outlasts the card you handed over.

A job you win in March is still running two years later, and by then your practice has moved, your extension number has changed and the card in the contractor’s van is wrong. Cardr keeps one card correct for the whole project and opens on a site with no reception.

Architecture is the trade where a business card has to stay right the longest. A residential project runs eighteen months and a commercial one runs years, across a cast of contractors, engineers, planners and clients who each took your details once at the start. Any of them changing is a chain of wrong numbers. Cardr is one card that corrects itself on every phone that holds it, and it opens on a site with no signal because the pass is stored on the device.

The real scene

A site, a hard hat, and no bars on the phone.

Half-built, steel-framed, below ground or behind hoarding. Reception on a live site is not a given.

Where it happens

The site visit

Half-built, steel-framed, below ground or behind hoarding. Reception on a live site is not a given.

  • Eighteen months The person you meet at Stage 2 needs to reach you at Stage 5, long after the details on the card went stale.
  • No bars Steel frames, basements and hoardings. Reception on a live site is not something to design around.
  • A whole cast Engineers, contractors, planners and clients all took your details once, at the start, and none of them will ask again.

Every constraint above is what decides the format. A card that fails any one of the three does not get used a second time, however good it looks.

A site visit is a bad environment for anything that has to load. Steel frames, basements, hoardings and rural plots all kill reception, and you are wearing gloves and holding a drawing. A pass that is already on the phone opens anyway; a card that is only a web page does not.

The longer problem is time. You meet the structural engineer at RIBA Stage 2 and they need to reach you at Stage 5, eighteen months later. In between, practices move office, people change roles, and direct dials get reassigned. Every one of those changes silently breaks a card handed over at the start.

The fix is unglamorous and it is the entire point of putting a business card in a wallet rather than on paper: you edit it once, and every consultant, contractor and client who saved you gets the corrected version without being told.

The card itself

What it looks like on the phone.

Not a mock-up. The artwork below is drawn by the same function that draws the inside of the signed .pkpass file, in the same colours the real pass carries, so this is what Wallet shows.

What you get

For a job that runs longer than your details do.

  • Correct for the whole project. New office, new number, new job title. Edit once and every phone holding your card updates. On a two-year job that will happen at least once.
  • Opens on site. The pass is stored on their device, so it works in a basement, behind hoarding, or on a plot with one bar.
  • The consultant team captured. Engineer, QS, contractor, planner: the exchange returns their details to you as a list rather than as a signature block you have to dig out of an email chain.
  • Which project, against the name. Notes and tags on Pro, so a contact reads “M&E, the Peckham job, prefers WhatsApp” rather than just a name and a firm.
  • Portfolio behind one link. A practice site or a project page, tapped from the card, rather than a PDF you have to remember to send.
  • Nothing to install for a client. Apple Wallet is already on their iPhone, which matters when the person you are handing to is not in your industry.
Questions

Architects, answered.

Will it open on a site with no signal?

Your own pass will, because Apple Wallet holds it on the device. Someone scanning your QR code for the first time needs enough signal to load the page once, which on a bad site can be the constraint. The reliable pattern is showing the pass, capturing their details through the exchange, and letting them add yours when they are back in the car.

Can I put my practice branding on it?

You can set the card’s colour to your practice colour and add your logo, and there are sixteen finishes to choose from. What you cannot do yet is host it on your own domain: every card lives at cardr.co/yourname. If a custom domain is a requirement, that is a real gap and we would rather say so here than have you find out afterwards.

Is this useful for a whole practice rather than one person?

Today it is built around an individual card. There is no team management, no shared contact pool and no admin console, so a practice would be running several individual accounts. If you need central control over a team’s cards, Blinq and Popl are both further along and our comparison pages say so.

Does it integrate with our project management software?

No. Cardr has no integrations at all today. Pro exports contacts to CSV and vCard, which covers getting them into most other systems manually, and that is the honest limit of it.

What does it cost?

Free forever for the card, the Apple Wallet pass and the two-way exchange, with no card details taken. Pro is £12 a month, or £9 billed annually, and adds the contact memory, drafted follow-ups and reminders. Sixty-day money back guarantee.
