Please help draw the activity diagram and sequence diagram for this case, ASAP

An automated ticket machine sells rail tickets. Users select their destination and input a credit card and a personal identification number. The rail ticket is issued and their credit card account charged. When the user presses the start button, a menu display of potential destination is activated, along with a message to the users to select a destination and the type of ticket required. Once a destination has been selected, the ticket price is displayed and customers are asked to input their credit card. Its validity is checked, and the user is then asked to input his or her personal identifier (PIN). When the credit transaction has been validated, the ticket is issued.
