Apple Pay is rolling out to all Saks Fifth Avenue, Albertsons, and Dick's Sporting Goods locations across the United States. It's also coming to McDonald's and Chipotle's order-ahead apps in several cities later this year.

Meanwhile, contactless tickets supported in Apple's Wallet app are coming to all Ticketmaster sports and concert venues in the United States.

Jennifer Bailey, Vice President of Apple Pay, revealed the news at the Money20/20 conference in Las Vegas over the weekend. On stage, she also revealed several other statistics about Apple's mobile payments service.

Namely, she said Apple Pay will be available in 20 markets after it launches in Denmark, Finland, Sweden, and the United Arab Emirates as early as this week. We've also heard rumors about Apple Pay coming to the Netherlands, Poland, and Norway, but Apple has yet to confirm a rollout to those countries.

Bailey said that Apple Pay now works with over 4,000 banks and other participating issuers around the world. She added that 50 percent of retailers in the United States now accept the mobile payments service.

As mentioned during Apple's most recent earnings call, Bailey echoed that Apple Pay is by far the most popular contactless payment service on mobile devices, accounting for nearly 90 percent of all transactions globally.

In related news, payment processor First Data today announced that Clover Go, its all-in-one contactless, chip, and swipe card reader, will be available in the coming weeks on Apple.com and in Apple retail stores across the United States.

First Data also said more than one million of its business clients now accept Apple Pay. The company plans to enable Apple Pay support for loyalty and gift cards at these merchants through integration with its Clover platform.

Meanwhile, Apple Pay Cash could launch alongside iOS 11.1 or shortly afterwards in the United States. Apple has invited both its corporate and retail employees to test the feature in beta over the past few weeks.
