Enable Vaccine Passport Verifier in Your App

With many businesses already mandating vaccine proof or COVID-19 testing to go back to work, and get into public areas. The adoption of implementing vaccination certificates is widely spreading. Rapidly build a vaccine passport checker with our enterprise-grade SDK to enforce health security protocols.

How the International COVID-19 Vaccination Certificate works

The International Civil Aviation Organization (ICAO) has specified a worldwide standard for digital vaccination certificates. It has a built-in QR code in a format called VDS-NC, which protects against forgery in the same way as the chip in a passport. Authorities can verify that the certificate is true and unaltered by checking the QR code against the Country Signing Certificate Authority (CSCA) public key.

Contact us if you need to support other common certification standards.

Implement Your Vaccine Passport Checker

Turn any camera-equipped mobile device into a vaccine verification system. Integrate our fast and robust QR code reader SDK into your existing mobile, web, or desktop application. Easily verify the vaccination status to protect the public health within your facility.

Step 1: Scan the embedded dense QR code

Supports All Platforms

Read QR code on any devices such as web apps on Windows, Mac or Linux, native apps on iOS or Android.


High-density QR Code

Built-in optimized algorithms to read high-density VDS-NC QR codes on the Vaccination Certificate.

Paper or Digital Certificate

Built-in optimized algorithms to read VDS-NC QR codes on paper certificates or mobile screens.

High Accuracy and Speed

Scan QR codes in milliseconds with the highest industry-leading accuracy with our enterprise-grade barcode detection algorithm.

Step 2: Verify the vaccine status by parsing the encoded information

Server-side Parsing

Conduct vaccine status verification regardless of the format the VDS-NC is presented in.

Client-side Parsing

Client-side parsing is currently under development.

  • 1. What is a vaccine passport ?
  • A vaccine passport is proof that you’ve tested negative for, recovered from, or been protected against certain infections. It can be digital, like a phone app, or physical, such as a small paper card. You can carry it with you and show it if requested, like before you go into the office, board an airplane, or visit a restaurant.
  • 2. What software development kit (SDK) does Dynamsoft provide for reading vaccine passport?
  • Dynamsoft provides a fast and highly accurate barcode reader SDK that scans QR Codes and decodes the information. Once the QR Codes are read, a separate module then parses the encoded information according to the certification standards.
  • 3. Which international and regional intergovernmental entities have released digital COVID-19 certification ?
    • World Health Organization (WHO)
    • International Civil Aviation Organization (ICAO)
    • European Union (EU)
