=begin Advanced Features

DBKK is very happy with their new public transportation system. Now they want more. 1. Card Expiry and Renewal Implement a mechanism for card expiration and renewal. Riders should be prompted to renew their cards when they expire, and their balanace journey history should be carried over. 2. Multiple Card Types Introduce different types of cards (e.g., student card, senior citizen card) with varying fare discounts. Extend the project to handle differenet card types and their respective discounts. 3. Advanced Error Handling Implement more robust error handling mechanisms, such handling edge cases, input validation, and better error messages for user intereactions. 4. Multi-Zone Fares Introduce a fare structure based on multiple zones crossed during a journey. Extend the fare calculation logic to account for different fare rates based on the number of zones. 5. Fare Discounts and Promotions Introduce periodic fare discounts or promotional offers for riders. Implement a mechanism to apply these discounts during fare calculation.
