Now a leaked memo from the burger chain pegs 26 August as the date when Android Pay is going to greet the world (in the US at least): AndroidPolice has received several tip-offs about the same date in the calendar.

The same memo also lists 21 August as the launch date for Samsung Pay - the service doesn't actually go live until 28 September in the US, but the Note 5 and the S6 Edge+ arrived on 21 August, so that might explain the discrepancy in the note issued to store staff.
