COVID Registration system

We are based in the UK and have deployed our tech team who usually work on our travel business to a new COVID registration system. Essentially, this will use a method of contact for visitors to the hospitality industry to register they visited through a QR code/URL. The details are stored securely and timestamped so incase of an outbreak, they can all be contacted.
The government are likely to issue guidance that the industry must register details of visitors from when they open so this will act as a 3rd party channel.
Data is held securely and only held for a given period of time before being destroyed.
We have a simple but effective system in place that works - the key is the simplicity to deploy and the venue does not have to worry about managing.
