How do QR code vaccine cards work?

Many governments adopted the QR code for verification during the COVID-19 pandemic to streamline entry at airports, workplaces, and public venues.

The QR code serves as an authentication tool for the certification, guarding its integrity against forged copies, illegal distribution, and inconsistent vaccination reports.

QR code statistics before and after COVID-19 show a significant increase in their adoption, particularly in healthcare, where they help verify vaccine authenticity and streamline record-keeping.

To access the QR code, you can use your smartphone and see if the details of the vaccine distributed are reliable and legit. 

For example, the dynamic URL QR code on vaccine cards leads to a landing page from the government or a health agency, showing the information and health status of the vaccine card holder. 

A QR code vaccine card or certificate provides a secure and scannable way to verify an individual’s vaccination status for travel, work, or entry into public venues.

The integration of QR codes in healthcare services solves issues of duplicity and falsification of vaccine records.

How to get QR code for COVID vaccine

Depending on where you are located, you may request a QR code for your immunization certificate from your local government or health agency.

Some countries may require you to download an app and use its QR code generator to create a QR for your vaccination. Others provide it readily for its citizens and residents.

Reminder: Only use the vaccination QR code provided by official government health offices or their affiliated hospitals.

How QR codes assist in vaccination roll outs

QR codes are easy-access tools to use in regulating vaccination roll-out drives.

One of the advantages of QR codes is their ease and speed of use and simple QR code generation.

Furthermore, QR codes can be decoded quickly using a QR code scanner, making them more efficient than traditional barcodes. 

They can store more information, allowing vaccine details to be embedded on vials and providing digital pamphlets about medical immunization.

Many countries introduced a QR code for COVID vaccine to verify vaccination status quickly and securely during the pandemic.

It is a reliable tool to verify vaccine distribution and provide legitimacy to its medical use.

Integrating QR codes into vaccination identification cards for immunized individuals in your country instills regulatory protocols.

Governments that incorporate vaccine QR codes on certificates and health cards

To maintain security and safety for every individual in a certain country, the dissemination of a travel QR code with vaccination details is greatly useful.

Here are some countries that incorporate QR codes for their vaccines and vaccination roll-out drives:

United States 

The Centers for Disease Control and Prevention, a public health agency of the United States federal government,  lets users access their COVID-19 vaccination certificate and generate a QR code as proof of vaccination.

When the health care provider records your vaccine dose in the agency’s Vaccine Administration Management System, the certificate is automatically created. 

The information in the certificates include vaccine date, manufacturer, clinic name, and lot number.

Meanwhile, California residents can get a Digital Vaccine Record (DVR) through the state’s official vaccine record website. 

The DVR contains a scannable QR code. This code can later be used for digital verification. 

European Union

The EU regulation establishing the EU digital COVID certificate was valid from 1 July 2021 until 30 June 2023.

The EU citizens who have been vaccinated, have tested negative or recovered from COVID 19 were issued a digital certificate.

The certificate consists of a QR code and a digital signature. To check the certificate, the QR code could be scanned. 

Ontario QR code 

In Ontario, Canada, the government implements the enhanced vaccine certification with an official QR code. Along with this is the launch of the free app called “Verify Ontario.”

These offer an easier, more secure, and more convenient proof of vaccination to their residents.

They also help businesses and organizations to quickly verify immunizations while protecting people’s privacy.

Saskatchewan Government

Residents of Saskatchewan in Western Canada can use their COVID vaccine card as supporting documentation when updating or verifying their immunization records.

A MySaskHealthRecord account at Saskatchewan Government eHealth provides a new format for COVID-19 vaccination records, including a Quick Response (QR) Code.

It has available information about the person’s immunization if they have been vaccinated outside the province or if their immunization record is missing.

Quebec Government

Quebec uses the VaxiCode application for its digital proof of vaccination during the COVID-19 pandemic.

The government also uses vaccine passport QR codes. The code imports information from the application. It reveals less personal information.

The implementation of a vaccine passport helped avoid widespread infection of the virus.

Update: The Government of Quebec no longer requires a proof of COVID-19 vaccination for travel outside the city as of April 19, 2025. The VaxiCode app has been phased out. 

Netherlands Government

In the Netherlands, citizens can convert their proof of vaccination into a COVID certificate using CoronaCheck QR Code.

This serves as a gate pass for an individual to travel within the European Union or Schengen and to enter events, food, and drink venues in the Netherlands.

On how to get QR code for COVID vaccine, the Dutch authorities instruct to either download the app or go to the CoronaCheck.nl website and log in using DigiD, an identity management platform used by government agencies in the country.

Then, people must upload any proof they have, such as proof of vaccination, proof of recovery, or negative test results. The app or website automatically creates a QR code.

Philippines’ Vax Cert

The official Philippine COVID-19 Vaccination Certificate—called VaxCertPH—is a digital proof of vaccination issued by the Department of Health (DOH) and the Department of Information and Communications Technology (DICT).

The vaccination certificate issued by the agency contains a QR code. It can be used for verification using an online or offline system.

To verify the QR code, users can visit the VaxCertPH website or install the eGovPH mobile app to scan it.

Government of India

The Government of India launched the COVID-19 Vaccine Intelligence Network (CoWIN) on January 16 2021.

CoWIN serves the function of registration, appointment scheduling, identity verification, vaccination and certification of each vaccinated member.

CoWIN issues a digitally verifiable vaccination certificate featuring a QR code. It enables secure and efficient proof of vaccination.

Government of Nepal

When an individual gets vaccinated from Nepal, they can get a COVID-19 vaccination certificate with a QR code through the government’s official portal. 

The QR code is linked to the official record stored in Nepal’s vaccine management system. 

It is used to digitally verify vaccination status, especially for international travel and official purposes.

The QR code also helps prevent fraud or document tampering.

Laos Government

In Laos, health authorities launched a new enhanced COVID-19 vaccination certificate with a QR code that allows the immunized individual to have greater authenticity and digital verification.

Benefits of using QR codes for vaccines and immunizations

QR codes have been a great help in securing and regulating vaccines and vaccination roll-out drives to any part of the world.

Here are some of the essential uses of QR codes in immunizations.

Prove the authenticity of the vaccine

Since the COVID-19 pandemic went on for three years, it was hard to prove whether the medicine is reliable for human consumption.

With the help of QR codes, healthcare brands are able to redirect healthcare professionals and patients to a custom landing page with essential vaccine information.

It shows the chemicals used inside the vaccine, its allergen factors, and others beneficial to human curiosity.

Quick access and verification to vaccination records

QR codes on vaccination cards make it easy to confirm someone’s vaccination status with just a quick scan.

Some countries in the Asia Pacific use QR codes for their vaccination identification cards instead of printing it on physical ones.

They already store necessary information about the immunization a certain individual has gone through during their primary and now years.

There is no need to manually check documents or enter data. It saves time at airports, workplaces, or event venues.

Fraud prevention 

Paper vaccine certifications can be lost, damaged or even forged. Since QR codes are digital databases, they are secure and authentic. 

Scanning the QR code will reveal real time data, making it harder for fake records to pass through checks.

You can also ensure that personal health information remains confidential and protected from phishing attacks by protecting it with a password.

Integration with apps

QR codes can be stored and scanned via apps like Apple Wallet or government health apps. This makes carrying it easier. 

Health providers and authorities can also sync QR data with vaccination databases or contact-tracing platforms, making it a seamless digital experience.
