Taken from an article in National Club Golfer last week - I used Golf Genious at an Open at Dundonald three years ago - works very well. The VMS system was going to be made available for this purpose "very soon" according to the V1 app last week (https://scottish.golf/)
"There are tournament management software providers, such as Golf Genius, that already handle hundreds of thousands of competitions worldwide completely virtually.
The firm, which powers nearly every state and regional golf association in the USA through its partnership with USGA Tournament Management, allows players to enter their scores for any type of event, and group size, through its app on a smartphone, as well as viewing live leaderboards and custom event websites.
Scotland’s Venue Management System will give participating clubs the opportunity to make their events completely digital.
From paying for a competition, to signing in, to entering scores and certifying a virtual scorecard which then uploads to the cloud, there is nothing a player won’t be able to do on a tournament day from their palm of their hand."
