From today (24^th September) certain businesses in England are required by law to display NHS Test and Trace QR codes so customers with the NHS COVID-19 app can use them to check-in. QR codes will help businesses meet their legal requirement to log contact details and allow public health leads to send alerts based on whether people have checked in at venues. So far, more than 160,000 businesses have already downloaded QR codes. Venues in Wales that are legally required to collect and keep a record of visitors will still need to do so.

The NHS Test and Trace team behind the app has worked closely with major tech companies, including Google and Apple, scientists within the Alan Turing Institute and Oxford University, Zuhlke Engineering, medical experts, privacy groups, at-risk communities and teams in countries across the world using similar apps – such as Germany, to develop an app that is safe, simple and secure.

The app has been through successful trials in the Isle of Wight, Newham and among NHS volunteer responders. Lessons learned have informed the final version now launched.

The app is available to those aged 16 and over in multiple languages. It forms a central part of the NHS Test and Trace service in England and the NHS Wales Test, Trace, Protect programme – identifying contacts of those who have tested positive for coronavirus.

The app has been designed with user privacy in mind, so it tracks the virus, not people and uses the latest in data security technology to protect privacy. The system generates a random ID for an individual’s device, which can be exchanged between devices via Bluetooth (not GPS). These unique random IDs regenerate frequently to add an extra layer of security and preserve anonymity.

The app does not hold personal information such as name, address or date of birth, and only requires the first half of a user’s  postcode to ensure local outbreaks can be managed. No personal data is shared with the government or the NHS.

UK government Health and Social Care Secretary Matt Hancock said:

“We are at a tipping point in our efforts to control the spread of this virus. With infection rates rising we must use every tool at our disposal to prevent transmission, including the latest technology.

“We have worked extensively with tech companies, international partners, and privacy and medical experts – and learned from the trials – to develop an app that is secure, simple to use and will help keep our country safe.

“Today’s launch marks an important step forward in our fight against this invisible killer and I urge

As well as contact tracing, the app has a range of additional, enhanced features that will help to reduce personal and public risk from COVID-19 as part of the wider testing and contact tracing service:

• alert: letting users know the level of coronavirus risk in their postcode district
• QR check-in: enabling users to check-in at a venue and alerting them if they have recently visited somewhere they may have come into contact with someone who later tests positive for COVID-19
• symptoms: allowing users to check if they have coronavirus symptoms and see if they need to order a free test
• test: helping users book a free test through the app and get results to know whether they have COVID-19
• isolate: if a user is told to self-isolate, a timer feature will help count down that period and access will be provided to relevant advice
