What type of payment can customers use to purchase merchandise on properly equipped ships?

The Navy Cash card is specifically designed for use on Navy ships that are equipped with the Navy Cash system. This system facilitates transactions aboard ships in a secure and efficient manner, allowing sailors and service members to make purchases without the need for physical cash, which can be difficult to manage in a ship's environment. The Navy Cash card operates in a similar fashion to a debit card, where funds are preloaded onto the card, and users can spend against the balance.

While credit cards, cash, and debit cards may be commonly used in civilian contexts, the specific infrastructure and protocols on Navy ships emphasize the use of the Navy Cash card for transactions. This approach helps streamline purchasing and ensures that financial transactions are conducted safely and efficiently.
