In 2026, almost all cruise lines use a "cashless" onboard payment system that is linked to your room key or a wearable device (like a MagicBand or OceanMedallion). When you check in for your cruise, you must provide a credit card or a cash deposit to open your "onboard account." For every drink at the bar or meal in a specialty restaurant, you simply scan your card or medallion, and the charge is added to your final bill. Cash is not accepted for individual transactions at bars or dining rooms, though it is still used for "extra" tips or in the casino on some ships. Many travelers in 2026 opt for pre-paid beverage packages or "all-inclusive" deals that cover most food and drinks, meaning your scan will show a $0.00 charge. At the end of the cruise, you will receive a statement of all your purchases, and the total will be automatically charged to the card on file. This system is designed to make the vacation feel seamless, though it's easy to lose track of spending, so most cruise apps now allow you to monitor your real-time balance on your smartphone throughout the journey.
