Purchase an electronic Oyster card at a Tube station for £3, charge it with a cash value, and use it on the Tube or on buses around the city. You reload it with money as needed. Another option is a Travelcard, sold for a specific number of days (even one day) of travel and good for buses and for specific zones in the Tube system.
