Photographs of internal memos informing McDonald’s managers and crew members about the procedures for accepting Samsung Pay and Android Pay may hint toward the latter mobile payment option launching in the U.S. very soon – some reports have even suggested tomorrow, Aug. 26.

“This month, customers will be able to start using Samsung and Android mobile devices to pay for their orders, Samsung Pay begins August 21 and Android Pay begins August 26. Service procedures are the same as with Apple Pay,” read one of the notifications reportedly sent out to McDonald’s staff, as reported by Android Police.

An additional photo on Android Police’s site, which was originally taken by a reddit user named BlackMartian, further supports that McDonald’s is distributing the memo to multiple stores.

Android Police’s spottings, along with the provided photos, shows participating Android Pay partners will also receive decals for point-of-sale terminals (POS) to inform customers of the mobile payment options, Mashable reported yesterday.

But there is already one factual error in the leaked staff memos. Samsung Pay, Samsung’s own mobile payment system, did not launch on Aug. 21. The payment platform did in fact launch in Korea on Aug. 20, but will not be available in the U.S. until Sept. 28.

Mashable said it is likely McDonald’s internal communication mixed up Samsung Pay’s launch date with that of the Galaxy Note 5 and Galaxy S6 Edge+ mobile devices, which did hit the market last week.

Whenever it does actually launch, Android Pay will go head-to-head in the in-store mobile payments battlefield with Apple Pay and Samsung Pay and PayPal.

Google’s mobile wallet option will allow consumers to pay via their mobile device in store using NFC technology. It will be available at the same stores that enable the acceptance of every other mobile payments technology that leverages NFC technology, including Apple Pay. Android Pay will work with any phone that has an NFC chip installed and will run on KitKat operating systems or newer.

Google has yet to announce an official launch date for its mobile payment system which allows users running Android on their smartphones to make purchases.
