Ocean Medallion from Carnival Corp. & PLC hangs on a lanyard, cool and smooth against your chest as the cabin door clicks open without you touching a thing. No key card, no rummaging in pockets, just a quiet green light and a soft beep.

How the Medallion changes a day onboard

The Ocean Medallion is a waterproof, coin-sized disc with an embedded chip that identifies you everywhere on participating Princess Cruises ships. It replaces the classic cruise card for cabin access, onboard payments and check-in.

Passengers can wear it as a bracelet, clip, or necklace, and the system talks to thousands of sensors across the vessel to locate guests within a few meters. On a sea day, that means a waiter can walk straight to your lounger with the latte you ordered in the app.

What the tech can actually do

Carnival’s platform, branded “MedallionClass” on Princess Cruises, links the Medallion to the MedallionClass app for iOS and Android. Guests order food and drinks, book excursions, or chat with guest services without queuing at the desk.

The chip inside the Medallion uses short-range wireless technology and works without a battery, powered inductively by readers installed throughout the ship. John Padgett, former chief experience and innovation officer at Carnival, framed it as “frictionless” travel where the ship recognizes you before you even reach the counter.

Privacy trade-offs and first impressions

Onboard, some screens show your name and photo as you approach, which feels almost like walking into a hotel lobby where the receptionist already knows you. For some guests that is convenient, for others it raises privacy questions.

Carnival says the system tracks location only on the ship, uses encrypted data and stores payment information in line with PCI standards. Reviewers note that you can opt out of certain personalization features, though you then give up some of the smoother service.

Where the Medallion is available

The Ocean Medallion currently runs on Princess Cruises ships designated as MedallionClass, including Discovery Princess, Enchanted Princess and Sky Princess. It is automatically included in the fare, so there is no extra rental charge for the device itself.

German guests typically encounter the Medallion when booking Princess itineraries via local travel agencies or cruise portals rather than directly through Carnival in Miami. The wearable ships to the home address in many markets or is handed out at the terminal.

Impact on Carnival’s bigger picture

Carnival uses MedallionClass to differentiate Princess Cruises in a crowded premium segment and to nudge passengers toward higher onboard spending. Sensors and app data show where guests move and what they order, which helps fine-tune bar staffing and retail offers.

In the latest quarterly update, management highlighted record onboard and other revenue across the group, with new technology and experiences playing a role. For chief executive Josh Weinstein, such digital projects are part of driving yields rather than simply adding gadgets.
