Customers of Permanent TSB can now use Apple Pay to carry out transactions.
The service will be available to both the bank's personal and small and medium sized enterprise customers.
Apple Pay is a contactless method of payment that enables customers to pay for goods and services using their iPhone, iPad or Apple Watch.
It can also be used to pay for goods on certain websites using an Apple Mac computer.
"We continue to work quickly on bringing a broader range of innovative, customer-friendly features to our digital banking offering and will make further announcements shortly," said Jeff Harbourne, Head of Personal Banking at Permanent TSB.
Permanent TSB is the last of the five main retail banks here to offer the service, which launched in the Irish market in 2017.
Two weeks ago, Bank of Ireland began rolling it out to its customers.
Permanent TSB does not yet, however, offer Google’s alternative service, Google Pay.
Apple Pay is considered a safe method of payment as it biometric or passcode-based methods are used on the device to confirm the transaction.
A one-time unique dynamic security code is also generated by the system, so card details are not communicated in the process, stored on the device or on Apple’s servers.
Customers with Permanent TSB's Explore Current Account will earn 10 cent cashback every time they use Apple Pay to make contactless payments linked to their debit cards, which also attract a 10 cent incentive when they are used.
