I think you can purchase a ticket on your phone, then use the phone to pass through the ticket barrier at arrival.So in theory you can buy a ticket from Vauxhall to Waterloo from your home in say, Portsmouth, then use the phone to pass through Waterloo. Ticket inspectors on the train may help, but on ultra crowded commuter trains ticket inspectors have small chance of catching fraudsters.Before the BR police come knocking, I don't use BR anymore, and have a freedome pass if I need to go to London
