The product

QR and NFC are only ways into the system. The durable thing is the profile URL you own and can update at any time.

The card is not the product. The link is.

01

Profile

Name, role, location, phone, email, and website live in one structured record.

02

Permanent URL

Each person gets a clean public path at /c/[slug] that stays under your control.

03

Share anywhere

Put the URL behind a branded QR, an NFC tag, a screen, or a plain link.

04

Save natively

A carefully formatted vCard opens the phone’s native add-contact flow.

For the organization

The authenticated admin dashboard is deliberately simple: create a contact, edit details, open the public profile, or download its QR code.

CreateProvision a card from the person’s real contact record.
UpdateChange the profile without changing the printed object.
ReuseThe same URL works across QR, NFC, email, and web.
