| There's no point asking sailors aboard the USS Harry S. Truman for some cash. They don't need to have any. The aircraft carrier is among the first wave of cashless ships, with its crew relying instead on debit cards. Everywhere dollars and cents had been used before - from the vending machines on the mess decks to the ship store to the ticket booth at the carrier's recreation department - now takes only plastic. For the past two months, more than 5,000 sailors and Marines carried the debit-only MasterCards at sea. The cards were loaded with cash by crew members, who transferred money from their personal bank accounts by using one of five automated teller machines on board. The Harry S. Truman is one of 24 Navy ships that no longer use cash on board. With the card, sailors at sea can receive pay, access home bank and credit union accounts, transfer and withdraw money, and make purchases. |
