Why Teams Choose Nexus Over QR TIGER
Four key areas where GDK Nexus offers capabilities QR TIGER does not.
Client-Side Encryption
GDK Nexus encrypts QR content using AES-256-GCM directly in your browser. The encryption key exists only in the URL fragment, which browsers never transmit to servers. QR TIGER does not offer any client-side encryption capability.
Digital Business Cards
While QR TIGER can generate vCard QR codes, Nexus provides a complete digital business card platform with contact exchange, team management, and lead capture. Share cards via QR, NFC, or direct link with full analytics.
Built-In Lead Capture
Attach customizable lead capture forms to any QR code or business card. Captured data flows directly into your CRM through native webhooks. QR TIGER focuses on QR generation and does not include lead capture forms.
A/B Testing
Run A/B tests on your QR code destinations to find what converts best. Split traffic between variants and measure results with real scan data. QR TIGER does not offer A/B testing for QR code destinations.
Frequently Asked Questions
Common questions about choosing between GDK Nexus and QR TIGER.
Does QR TIGER offer client-side encryption?
No, QR TIGER does not offer client-side encryption for QR code content. GDK Nexus uses AES-256-GCM encryption that runs entirely in your browser, with the encryption key stored only in the URL fragment. The server never sees your plaintext content.
Can I create digital business cards with QR TIGER?
QR TIGER offers limited vCard QR code functionality but does not provide a full digital business card platform with contact exchange, lead capture forms, or team management. GDK Nexus includes dedicated business card creation with vCard export, two-way contact sharing, and organization management.
How does password protection compare between QR TIGER and GDK Nexus?
QR TIGER offers basic PIN protection for QR codes. GDK Nexus uses bcrypt cost-12 password hashing combined with AES-256-GCM encryption, providing significantly stronger security. With Nexus, the password is used to derive an encryption key, so content is cryptographically protected rather than just gated behind a PIN.
Does GDK Nexus support lead capture like QR TIGER?
Yes, and GDK Nexus goes further. While QR TIGER focuses primarily on QR code generation, Nexus includes built-in lead capture forms with custom fields that can be triggered by QR code scans. Captured leads flow directly into your CRM through native integration, without requiring third-party connectors.
Which platform is better for bulk QR code generation?
QR TIGER has a strong reputation for bulk QR code generation and is a solid choice if that is your primary need. GDK Nexus also supports dynamic QR generation but differentiates with client-side encryption, A/B testing, lead capture, and digital business cards, making it the better choice for teams that need more than just QR codes.
