Digital business card
One QR. A live page. Call, WhatsApp, email, website, and save-to-contacts — then change any information without reprinting. Built by StackGB for people who still hand out paper and regret it later.

Why this exists
Paper freezes. Static QRs freeze. A live card does not.
Most “digital cards” encode a vCard or PDF at print time. Ours open a page you control. That is the whole product: print once, revise forever, and give every visitor every channel — not just WhatsApp.
Paper card
- Wrong number means a reprint
- Usually one channel (phone or email)
- Easy to lose; hard to update
Static QR → PDF / vCard
- Details frozen at print time
- Often dumps into one action
- Ugly defaults; weak branding
StackGB live card
- Edit anytime — same QR
- Call, WhatsApp, email, web, save
- Designed QR + public slug
Capabilities
Everything that ships today
Not a roadmap slide. These are the controls and actions in SuperDash and on the public card page right now.
01
Live page, not a dead QR
The code opens your card on stackgb.com. Change phone, email, website, or name later — the same print still works.
02
Every channel, equal weight
Call, WhatsApp, email, website, and save contact. Visitors pick how they prefer to reach you — none of them is second-class.
03
Save to contacts (Android & iPhone)
One tap hands a real vCard to the device contacts app — phone numbers, WhatsApp link, email, and website included.
04
Branded QR designs
Five colour presets, square / rounded / dot modules, optional centre brand mark, and a print caption you control.
05
Download print-ready PNG
Export a high-error-correction QR for flyers, booth banners, email signatures, and packaging — not a screenshot from a phone.
06
Your public URL slug
Share /card/your-name as well as the QR. Useful in bios, invoices, and places a camera is awkward.
07
Company or person cards
Lead with the company, or add a name and job title when the contact is a specific person. Optional note on the page.
08
Mobile and work numbers
Store both. Call and WhatsApp use your primary number; both appear in the saved contact when they differ.
09
Free plan — up to 3 cards
Personal card, events booth, and a side brand — without a subscription wall on day one.
10
Sign in your way
Username and password. Edit your cards from any device once you are in.
11
Details that stay honest
Wrong number after a rebrand? Fix it in SuperDash. Scanners always hit the current page — no reprint cycle.
12
Built by a software engineering firm
StackGB ships production systems for clients. This free tool uses the same product discipline — not a throwaway landing page.
How it works
Four steps. No app for your visitor.
01
Sign in with email
Sign in to SuperDash with your email and password. No app install for you or your visitor.
02
Build the live card
Company, phone, email, website, optional person details. Pick a public slug and QR style.
03
Download the QR
PNG with high error correction when a centre label is set — ready for print and screen.
04
Share and revise
Booth, packaging, LinkedIn, invoices. When information changes, edit once — codes keep working.
Where it earns its keep
Built for real handoffs
Events and trade shows
Print one badge QR. Collect interest without typing numbers under fluorescent lights.
