Customers of AIB can use the Apple Pay service from today.

The bank says the mobile payment technology will work with its debit and personal credit cards everywhere contactless payments are accepted.

When Apple launched the service in Ireland in March, just two banks offered it - KBC and Ulster Bank.

AIB also offers the competing mobile payment service from Google; Android Pay.

Bank of Ireland and Permanent TSB still do not offer either Apple Pay or Android Pay to their customers.

Apple Pay enables customers to pay for goods and services by swiping their iPhone or Apple Watch over a contactless payment terminal in a participating shop.

The company says the system is secure and private, because a unique Device Account Number, not the card number, is assigned, encrypted and securely stored in the device.

Each transaction is then authorised with a one-time unique dynamic security code.

Apple Pay works with iPhone SE, iPhone 6 and later, and Apple Watch.

The system can also be used to pay for goods and services on participating apps and websites.
