Revolut, the digital bank start-up, said it could pinpoint customers' location through its app technology and automatically turn on the coverage when required, starting at less than 1 pound ($1.38) a day.

"We wanted to create a type of insurance that uses technology to help our customers and only cover you on the days you actually needed to be covered," Revolut CEO Nikolay Storonsky said in a statement.

Revolut was founded in July 2015 and has grown quickly, with 1.2 million users globally and around 600,000 in Britain. It allows customers to exchange currencies at rates used by banks and pay by card in different countries without international fees. In December, it also launched cryptocurrency trading.

Thomas Cook Money, the new financial arm of Thomas Cook, will partner Revolut to underwrite the insurance policies.
