Apple has again updated its list of Apple Pay partners by adding another 30 credit unions and banks, and is continuing to focus more lately on credit unions in the latest additions as it has done with recent updates. Personal and branded cards from the financial institutions can be added to Apple Pay in most cases, though small-business and sub-branded speciality cards may not always be compatible. Since its launch last fall, Apple Pay has nearly instantly become the most popular of the various mobile-payment services, despite only being available on the iPhone 6 (and now, Apple Watch).
