## What is ID2D?

EcoQCode ID2D is the next-generation QR code solution for secure data sharing. With ID2D, you can generate QR codes containing both public information and encrypted secret data, protected by a unique EcoQCode encryption key. Built for the UKSG Co innovation project.

How It Works:
Generate Secure QR Codes – Create QR codes that include public data, secret data, and an encryption key.
EcoQCode Key Protection – The encrypted portion can only be unlocked by scanning or uploading the matching EcoQCode key.
Scan & Reveal – Users can scan/upload a generated QR to view public data and, if they have the correct EcoQCode key, decrypt the hidden data.

Why Choose EcoQCode ID2D?
Unlike traditional QR codes, EcoQCode ID2D lets you securely share sensitive information while keeping public data easily accessible.
Only users with the correct EcoQCode key can unlock encrypted secrets, making it ideal for businesses, private communications, and personal data protection.
