NEW YORK (AP) — U.S. users of Discover cards are getting their Apple Pay, the last holdout among major credit card networks in the country.

After months of complaints from customers, Discover Financial Services announced Monday that it has reached an agreement with Apple Inc. that will let its cardholders make payments in participating stores through Apple Pay by using an iPhone 6, iPhone 6 Plus or Apple Watch.

With Apple Pay, credit card numbers are not stored on the device or on Apple servers. A unique device account number is assigned and each transaction is authorized with a one-time unique security code. Apple Pay launched in October.

"As the mobile payments landscape matures, Discover remains committed to giving cardmembers secure options for using their cards and mobile devices," Diane Offereins, Discover's president of payment services, said in a printed statement.

American Express, Visa and MasterCard came on board late last year.

Discover customers will also be able to use Apple Pay with iPad Air 2 and iPad mini 3 when paying for goods and services within apps starting in the fall.
