Digital business card for architects The project outlasts the card you handed over.
A free card you correct once: everyone on the project saves it, and it stays right from the first meeting to completion.
Free forever · No card details · About a minute

Example of what happens next: Paul Grant scans Idris’s card, saves Idris to their contacts and chooses to send their own details back. The next morning at 09:00, Cardr Pro reminds Idris to follow up, with the email already drafted.
The engineer you met at Stage 2 rang your old number at Stage 5. Projects run eighteen months or more, and details change. Cardr is one card you correct once: engineers, contractors and clients save it, can send their details back, and your pass opens on a site with no signal.
One scan. You’re in their phone. They can send theirs.

Change your details once. Every saved contact links to them.
Example
A site, a hard hat, and no bars on the phone.
The site visit
- Eighteen months
- No bars
- A whole cast
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.
Each constraint decides the format. A card that fails any one of the three does not get used a second time, however good it looks.

- Edit once, it updates
- Residential, retrofit · RIBA 2 to 5
- One scan, no app
- Opens with no signal
Steel frames, basements and hoardings kill reception, and you are holding a drawing. Your pass is on your phone, so the code opens anyway; the person scanning needs signal to load your page.
The longer problem is time. You meet the structural engineer at RIBA Stage 2, and they need you at Stage 5, eighteen months later. In between, practices move office and direct dials change, and each change breaks a card handed over at the start.
The fix is plain: edit your card once, and every consultant and client who opens your link, scans your code or taps the page in their saved contact gets the new version.
Nothing for them to download.
Tap through what Tom sees when he scans your card.

Make yours in about a minute.
Free forever, and nothing for the people you meet to install.
For a job that runs longer than your details do.

Will it open on a site with no signal?
Your pass will, because Apple Wallet holds it on your phone. If their phone has no signal either, open cardr.co/me/code and switch to No signal: that code holds your contact itself, so their camera saves you. They can send their details from your page back in the car.
Does a client need an app?
No. Your QR code opens your card as a web page on their phone, iPhone or Android, and they save you to their contacts from there. Nobody downloads an app or creates an account.
Can I put my practice branding on it?
Your practice name goes on every card. A practice colour and all 16 designs are Pro; Free wears Oxford. The practice logo on every card comes with Cardr Teams. Cards live at cardr.co/yourname, not your own domain.
Can I call myself an architect on the card?
Only if you are on the ARB register (landscape, naval and golf-course architects excepted): section 20 of the Architects Act 1997 restricts the title in business (legislation.gov.uk, read 29 October 2026). Cardr shows the title you enter and does not check it.
Does it integrate with our project software?
No. Cardr has no integrations. Every plan, including free, exports contacts to CSV and vCard.
What does it cost?
Free forever, no card details: your card, page and Apple Wallet pass, the two-way exchange, and every contact with notes, search and export. Pro, £12 a month or £108 a year (£9 a month), adds drafted follow-ups, reminders and all 16 pass designs. 7 days free, then 30 days to change your mind.
Free forever. About a minute to build.
Nothing for the other person to install, and no card details to start.
