The following is a description of a ticket issuing system for rail travel: The ticket issuing system is intended to automate the sale of rail tickets. Users will be able to select their destination and input a credit card and a personal identification number. The rail ticket is then issued, and the user's credit card account is charged with its cost. When the user presses the start button, a menu display of potential destinations is activated along with a message to the user to select a destination. Once a destination has been selected, the user is requested to input his or her credit card. Its validity is checked and the user is then requested to input a personal identification number. When the credit transaction has been validated, the ticket is issued. List the inconsistencies, ambiguities, or omissions in the above statement of requirements. Rewrite the statement (750 - 1000 characters) to clarify the description and correct the problems you found.
