Which type of Navy Cash card is intended solely for purchases onboard the ship?

The correct choice is the temporary card, which is specifically designed for purchases made onboard the ship during a sailor's deployment or while on active duty. Temporary cards are generally issued to personnel who may not have a permanent card due to the nature of their assignment or because they are new to the ship. This card serves the purpose of enabling transactions for onboard amenities such as the ship's store, vending machines, and other services without the need for cash.

In contrast, permanent cards are issued to sailors who will remain aboard for an extended period and are typically tied to their service records. A standard card might refer to a more general usage card that could be valid both on and off the ship, while a disposable card usually has a one-time use or is intended for temporary, low-balance uses, making them less suitable for regular transactions on the ship. Understanding these different types of cards helps ensure that personnel use the appropriate card type as intended for their specific needs while aboard.
