Digital bank Revolut is prompting some customers to upgrade their debit cards for free before June 21st.
Failure to do so could see the cards not working past a certain point.
The change is due to the British fintech company becoming a full digital bank.
Newstalk's technology correspondent Jess Kelly told Breakfast what is going on.
"It's actually a good thing, because we're going to get a whole host of new features from Revolut over the coming weeks and months.
"They're prompting customers now to upgrade their cards completely for free - you don't even have to pay for shipping.
"You'll get an e-mail or a notification within the app, saying 'Your card needs to be upgraded so you get access to these features'.
"Follow the steps, and you'll have your card within a matter of days".

"Revolut is going to merge to become an official bank, we're going to have IBAN numbers later this summer.
"So it's all good news; you just need to ensure that you have the latest version of the card to be able to access all of these features".
The new suite of Revolut services includes personal loans and deposit accounts.
Customers will have deposits of up to €100,000 protected under a guarantee scheme.
This is covered by the Lithuanian State company Deposit and Investment Insurance, where Revolut is based for its Irish customers.
