Design a system for reloading bus transit cards using an ATM-like interface.

To design a system for reloading bus transit cards via an ATM-like interface, we need to consider two primary components: the user's bank account and the bus transit card system. The bus transit card system would maintain an account for each card, linked to the card's unique identifier. Users would link their bank accounts to this system, similar to adding a beneficiary in online banking. The ATM interface would then facilitate the transfer of funds from the user's bank account to their bus transit card account. This involves authenticating the user, verifying their bank account and transit card details, confirming the reload amount, and executing the transaction.
