The NHS COVID Pass Verifier app

The official NHS COVID Pass Verifier app is a secure way to verify an individual’s NHS COVID Pass and check that they have been fully vaccinated against COVID-19, had a negative test, or have recovered from COVID-19.

A user can use the app to scan and verify an individual’s NHS COVID Pass for use in England such as entry to venues and events.

The app can be used to scan a 2D barcode and display the data held within an individual’s NHS COVID Pass. It does not store or transmit any personal data during this process.

This user guide helps venue stewards to use the NHS COVID Pass Verifier app to show if an English or Welsh citizen is eligible to enter a venue by scanning their NHS COVID-19 Pass 2D barcode.

Visitors from other parts of the UK

From 30 September, visitors from Scotland, Northern Ireland and Jersey can show their international digital NHS COVID Pass at venues and settings in England. Users from England and Wales can use their domestic NHS Covid Pass as usual.

The NHS COVID Pass Verifier app can be used to scan the 2D barcode displayed on your customer’s phone or printed as a PDF. Scanning of these COVID Passes can be done using the NHS COVID Pass Verifier app in domestic mode.

The protection of user privacy is central to the NHS COVID Pass Verifier. Its purpose is to display COVID Pass status information in a clear and readable manner upon each scan.

The NHS COVID Pass Verifier app does not retain personal data. It only gathers metric-related information about the application itself, in order that the performance of the app can be monitored. The collected metric data cannot be referenced back to any individual NHS COVID Pass user.

Read the Verifier terms and conditions.

Step 1

Staff will need to download and install the Verifier app on a mobile device. The app is available from either the Apple App Store (for iOS Apple devices) or Google Play (for Android devices). See visual of the app in yellow.

The NHS COVID Pass Verifier app works both in offline and online mode, both with or without wifi. However please note that the app will need periodic access to the internet to download public key certificates that it uses to check the validity of the COVID Pass. A public key certificate, also known as a digital certificate or identity certificate, is an electronic document used to prove the ownership of a public key.

Step 2

Open the NHS COVID Verifier app by clicking on the yellow NHS COVID Pass Verifier app logo (step 1).

When used for the first time, the consent agreement screen will display. The first time the user applies the Verifier app, the user is asked to agree on a consent form, by clicking "I agree". The app will not function if user agreement is not obtained.

When opening the camera on your mobile device for the first time, please click "OK" to allow the app to have permission to use the camera. The screen shot below is from an Android phone. A similar screen and permission request will display on an iOS (Apple) phone.

To scan the NHS COVID Pass of your customer or employee

Your customer or employee will show their NHS COVID Pass. This will be on a smartphone, tablet or printed off as a paper PDF.

Direct your mobile’s camera at the 2D barcode displayed on the guest’s printed PDF, or at the 2D barcode displayed on their smartphone. Once the scanner has been pointed at a 2D barcode, it automatically starts scanning the code.

Note: The Verifier app can scan the NHS COVD Pass via a mobile or tablet or where someone has printed off a PDF version from their phone. It is not able to scan the 1D barcode on a letter which your customer has requested by telephoning 119.

Valid

With a "valid" screen, ensure the expiry date is still valid. If the expiry date has expired, it is likely that your guest or customer will need to take another lateral flow test.

Note the expiry date refers to the barcode and will update automatically within the NHS App. If the 2D barcode has expired, the expired screen will be shown.

Not recognised

If this screen is displayed saying "2D barcode not recognised", this may be because the scanned barcode is an incorrect code, or a section of a valid code has been obscured.

Press "Hold to pause". This pauses the screen with the result for approximately 3 seconds. You should see the screen where you can scan the barcode.

Using Apple Wallet

Your customer can store their NHS COVID Pass for domestic use into their Apple Wallet using an Apple iPhone. To do this, they will see the ‘Add to Apple Wallet’ button on their phone screen within the NHS App. If they store both international and domestic NHS COVID Passes, they will see two separate cards stored in their Apple Wallet.

You will be able to verify their NHS COVID Pass using the Verifier app by scanning their 2D barcode, as detailed in this user guide. The screen you will scan can be seen below. Please ensure you check the expiry date shown on their COVID Pass as the date does not refresh automatically. Customers need to store an updated NHS COVID Pass in their Apple Wallet before they next plan to use it, if their original COVID Pass is due to expire.
