What is DiagBizCard?
A free public business card for the business you built.
DiagBizCard is a free public business card and directory listing. It is a straightforward way to present your essentials in one place — contact details, services, social links, and QR codes. It is not a diagnostic, score, AI result, paid hub, subscription, or automatic marketing system.
When someone looks for your business, clarity wins. Your card gives them one clear place to find accurate details and take the next step — contact, review, or save.
Three actions that turn a listing into a working card.
Every DiagBizCard puts the three most useful customer actions one tap or scan away — so when someone finds your business, they can actually reach you.
Why a card works
Be found. Stay current. Free forever.
Print-ready QR codes for every action.
Each primary action on your card has its own QR code — so a customer can scan to contact you, leave a review, or save your details. Plus a permanent Share this card QR for printing and in-person networking.

How does DiagBizCard help with reviews?↓
Each card features a dedicated 'Leave a review' primary action with its own QR code that routes customers directly to your Google or review destination.
What is the difference between DiagBizCard and DiagLoop?↓
DiagBizCard is the public-facing customer gateway and digital business card for local businesses. DiagLoop is an independent internal system for teams to automate follow-ups and workflow management.
Does a card start marketing messages or AI?↓
No. Publication of a card does not create a paid plan, subscription, AI activation, marketing consent, voice/SMS, booking, or payment obligation. The free card remains available even if optional future services are declined.
How do I claim my listing?↓
A claim is started only from an unclaimed business card using its 'Claim this listing' button. A submitted claim starts verification — it is not ownership verification in itself.
