Wearable technology made from recycled ocean plastic will be introduced for passengers on Virgin Voyages first ship Scarlet Lady.
The Band will enable users to access cabins and make payments on board when the ship enters service from Miami on April 1.
An app will be available in the coming weeks for passengers to complete the check-in process and book shore excursions.
The technology was revealed ahead of the adults-only ship arriving in Dover on February 21 for a trade and media preview.
The Band will contain six grams of marine and coastal plastic, equivalent to one-half of a plastic water bottle that washes ashore, according to the line.

It has been developed by specialist material engineering company Bionic.
Virgin Voyages chief executive Tom McAlpin said: “Just like our stunning fleet of Lady ships, and through our partnership with Bionic, our wearable technology marries sustainability with smarts and style, which is quintessentially Virgin.
“The Band will be our seamless and worry-free way for sailors [passengers] to not only unlock their cabin with ease, but to explore all of the thrills and great experiences that Scarlet Lady and the rest of our fleet will have to offer.”
