Systems, methods and computer programs provide for automated initial and final payment for an activity based on determining the location of an activity participant's mobile communication device. The described embodiments provide for the activity participant to automatically pay for the activity based on their presence at the activity location and agreement to participate. As such, the need to check-in and/or pay for the activity at a conventional payment counter is eliminated. Further, the invention provides for an automatic final payment to be made at the conclusion of the activity as opposed to having to pre-pay for the activity prior to conducting the activity. By remitting final payment at the completion of the activity, activity pricing can be accurately determined based on the amount and/or time of the activity in which the activity participant participated.
