GDK Nexus

Digital Business Cards & QR Codes

Create dynamic QR codes, share contact information instantly, capture leads at events, and track every scan with real-time analytics. The modern way to connect.

The Problems We Solve

Paper Cards Are Dead

You hand out 500 business cards at a conference. Half get lost. The other half sit in a drawer. No tracking, no follow-up data, no ROI.

Static QR Codes Break

Printed a QR code on marketing materials? If the destination URL changes, every printed code is useless. Static codes cannot be updated or tracked.

No Lead Capture

You meet a prospect, exchange cards, and then manually type their info into your CRM. Leads fall through the cracks between the handshake and the follow-up.

Dynamic QR Codes That Work for You

Create, customize, and track QR codes that never go stale.

Real-Time Analytics on Every Scan

Know exactly who scans your codes, when, where, and on what device. Update destinations without reprinting. Track campaign performance across locations.

Frequently Asked Questions

What types of QR codes can I create?

GDK Nexus supports URL, vCard, email, phone, SMS, Wi-Fi, plain text, and encrypted QR codes. Dynamic QR codes can be updated after printing - change the destination without reprinting.

Is there a free plan?

Yes. The free tier includes QR code creation, a digital business card, and basic analytics. Upgrade for advanced features like A/B testing, password protection, and lead capture forms.

Can I protect my QR codes with a password?

Yes. Nexus supports bcrypt password hashing and optional AES-256-GCM client-side encryption. Protected QR codes require a password before the content is revealed - the server never sees the plaintext.

How does lead capture work?

Attach custom forms to any QR code. When someone scans it, they see your form and can share their contact information. Leads sync to your GDK-CRM pipeline automatically with duplicate prevention.

What is A/B testing for QR codes?

Split traffic between multiple destinations with weighted percentages. Test different landing pages, offers, or CTAs to see which performs best - all from a single QR code.
