NHS COVID Pass Verifier terms and conditions

Updated 23 Jan 2023

By using this Verifier app, you agree to these terms.

1. Introduction

1.1. These are the terms of use (“terms”) for the NHS COVID Pass Verifier app (“Verifier app”). The Department of Health and Social Care ("DHSC", "we", "our") has overall responsibility for the Verifier app, which has been developed by, and will be operated by NHS Business Services Authority.

1.2. These terms apply to the Verifier app only. There are separate terms of use that apply to the NHS COVID Pass Service (“Service”).

2. Purpose of the Verifier app

2.1 The purpose of the Verifier app is to allow the device onto which the Verifier app is downloaded to scan and read a 2D barcode produced by the Service, which shows whether or not the user has a COVID Pass. A COVID Pass confirms that the Service user has been fully vaccinated against COVID-19 or has met negative testing requirements. The Service user can use the COVID Pass to demonstrate their COVID status for international travel or for domestic purposes which the government may approve from time to time.

2.2 The Verifier app is only designed for use in conjunction with the Service, or with compatible COVID passes that are equivalent to the Service (where such compatibility has been approved by DHSC), but not for any other purpose. Notwithstanding that the Verifier app may be available for download in other countries or territories, it has been designed for use in the United Kingdom.

2.3 The Verifier app is provided by DHSC free of charge, and it is expressly prohibited to attempt to sell or license use of the Verifier app to any person, or to include the Verifier app as part of a paid-for service or product.

2.4 International barcodes are only to be checked by travel operators, for the purposes of verifying an individual's COVID Pass and determining if it meets the international destination’s requirements, or by venue operators, where no domestic alternative is available. The service must not be used for any other purpose.

3. How to use the Verifier app

3.1. To use the Verifier app, you must first download it from the Apple App Store or Google Play Store. You should refer to the terms of use and privacy notices applicable to each app store when visiting those stores to download the Verifier app.

3.2. Upon navigating to the 2D barcode verifier, you will first be met with the initial landing page. This page is the first page in the application where you are always able to navigate back to or progress to the 2D Barcode verifier.

3.3. The “Check 2D barcode” button will navigate you to the 2D barcode verifier where you will be able to direct the camera at a user’s COVID certificate. To do this, the user's 2D barcode, which will be either on their device or printed out, will need to be placed inside the four blue square guidelines.

3.4. International results: the international 2D barcode represents the COVID status of an individual person. It follows set international standards designed by eHealth Network (part of the European Commission), and all developers who develop COVID related applications follow this set standard. It is intended to be used for international travel.

3.5. Domestic results: the domestic results of a COVID-19 2D barcode can hold two possible statuses. The first status is valid, which represents a valid certificate (based upon vaccination, exemption or testing) of an individual user. The second status is expired, showing an expired certificate of an individual user. When represented on the app, the verifier (the person, organisation or business using the Verifier app) will see the name, status, and date of expiry.

3.6. About your data: The NHS COVID Pass Verifier application reads 2D barcodes that store personal data and allow the app to display this information. However, this information gathered from the 2D barcode is never stored or transmitted on the NHS COVID Pass Verifier application. App permissions are used to securely store keys that are used to verify that a 2D barcode has been signed by a trusted authority. These permissions are not used to store any data related to the user or app usage. The storage used does not hold any personal data. Nevertheless, in using the app to read the personal data contained in the barcode, the verifier (not DHSC) may owe obligations to you under data protection laws, and you may have rights in relation to their use of your personal data. You should refer to the verifier's notices and policies for more information.

4. Your right to use the Verifier app
