CNET -- Apple Pay has a new credit card in its fold, namely the American Express corporate card.

Unveiled last October, Apple Pay enables owners of the iPhone 6, iPhone 6 Plus and Apple Watch to pay for items on the go via a wireless technology known as near-field communication, or NFC. Other Touch ID-enabled devices, such as the iPad Air 2 and Mini 3, can use Apple Pay for in-app transactions.

In the US, Apple Pay already supports Visa, Mastercard, Discover and American Express for consumers and small businesses. With the new move, American Express becomes the first corporate credit card to work with Apple Pay, potentially opening up a whole new and wider audience.

Apple has been striving to expand Apple Pay support among credit card companies, bank and retailers, both in the US and the UK. The company has been successful at winning over credit card providers and financial institutions -- more than 400 banks and credit unions are onboard.

Signing up retailers is a more complex matter.
