It is now mandatory for hospitality venues to keep a temporary record of your customers and visitors for 21 days, and assist NHS Test and Trace with requests for that data if needed.
As part of this, the government has produced NHS QR code posters for visitors to use. You can use this as well as, or instead of your existing system, but you should ensure you have an alternative if anyone cannot use / scan QR codes.
Blackburn BID is offering free access to a customer recording system – please contact Catherine.firstname.lastname@example.org if you would like to be set up for this.
