Revolut users are set to experience a major change to the financial institution's services, with the impact to be felt within weeks.
Some users' cards will no longer be valid after an announcement from the company following its official launch as a bank earlier this year.
Customers will need to update their current, older cards to continue to use Revolut's services soon as these will cease to work after June 21.
In an email, the company said: "We got in touch not long ago to let you know we've made some changes to improve your card payment experience.
"We want you to benefit from these changes, so don't forget to order your free replacement debit card…"
It added that existing cards will continue to work until June 21 and that it would be issuing a warning before they stop working.
"Your Revolut account and any other Revolut cards you have will still work as normal," it said.
"Order your free replacement cards and we'll deliver them to an address that suits you in any of the 150+ countries we deliver to. Track your delivery in app and remember to add your card to Apple Pay or Google Pay to start using it straight away."
If a customer did not receive a communication from Revolut, there is no need to order a new card or take any action.
