Apple Pay users in China added three million payment cards to the mobile payment service within the first 72 hours after its launch there in February, Apple exec Greg Joswiak said at the company’s iPhone event on Monday.
That total is three times bigger than the one million cards that were added to Apple Pay in the first three days after its initial launch in the U.S. in 2014.
The context: Three million payment cards is not the same as three million users, since people can upload multiple cards to the tap-to-pay service. It’s also important to note that there are more devices that work with Apple Pay today — the Apple Watch, for example — than there were when the service was first unveiled in late 2014.
Apple Pay has also launched in the U.K., Canada and Australia.
