Update: Apple has removed support for prepaid cards from American Express. It also added a column for corporate cards, hinting that support for those cards might be on the way.

With Apple’s launch of its new Apple Pay payments service in the US yesterday, it has now published a support document detailing supported card types from each of its initial banking partners. We already knew that MasterCard, Visa, and American Express cards would be supported initially through a growing list of banking partners, but the support document shows certain types of cards, like business and corporate cards, aren’t yet supported through some banks.

While Apple said that it has 500 banks signed up for the service, it currently only lists American Express, Bank of America, Capital One, Chase, Citi, J.P Morgan, Merrill Lynch, U.S. Trust, and Wells Fargo. Of the currently supported banks, only American Express and Capital One are listed as supporting small business credit cards, for example. Capital One and J.P. Morgan, on the other hand, don’t support Co-branded cards (Airline, hotel, retail, rewards), while the other banks do.

Other limitations are outlined in Apple’s support doc (pictured above) and the company confirms that “Corporate cards can’t be used with Apple Pay.” Some of the other banks don’t support prepaid cards, small business debit cards or personal debit cards. 

You can expect Apple to add many more banks to the list in the coming weeks as Visa and MasterCard have already confirmed support for a long list of banks. Visa announced support for Barclaycard, First National Bank of Omaha, M&T Bank, PNC, Navy Federal Credit Union, Regions Bank, USAA, and U.S. Bank in the coming weeks, and MasterCard provided an even longer list of banks for the “coming months”: Cardholders with a MasterCard consumer credit or debit card from Barclaycard, USAA, PNC, Navy Federal Credit Union, US Bank, Fifth Third, First Hawaiian, First National Bank of Omaha, First Niagara, Key Bank, Silicon Valley Bank, SSFCU, SunTrust and Synchrony Financial

Earlier today we noted that readers reported using the service successfully abroad through supported NFC terminals using US-based cards, but Apple and the credit card companies aren’t yet talking about international availability.
