Apple Pay just got another boost in institutional support.

Almost 40 banks and credit unions have been added to Apple Pay’s already considerable roster of supports in the US – largely regional firms like Sanborn Savings Bank and Regional Missouri Federal Credit Union, since the country’s biggest banks were already on board. Abroad, Danske Bank in the UK, China’s Bank of Hainan, and Canada’s MBNA have all added their support for Apple’s digital payment service, as well.

Meanwhile, as part of a larger effort to improve its public image, Uber has launched a new tipping feature for its mobile app, which supports Apple Pay payments.

Available in 16 markets around the world, Apple Pay is thought to be leading the emerging mobile payments industry, with Apple CEO Tim Cook having asserted in his company’s Q1 update that Apple Pay transactions were up 450 percent compared to a year ago. The new support thus bolsters the service’s position, and points to continuing momentum in its growth.
