Abstract: A method and system for obtaining payment from a customer that includes receiving a collection request at a payment facilitation device from a payment collection request device of a merchant, storing the collection request in a collection request repository, determining, using the collection request, a location of the customer, and determining, using the location of the customer, that an in-person payment device of a collecting entity is located near the location of the customer. The method also includes transmitting a notice of collection request to the in-person payment device and receiving a payment request from the in-person payment device at which the customer made a payment via the in-person payment device after the notice of collection request was received by the in-person payment device. Additionally, the method includes transmitting, based on the payment request, a payment to a merchant account associated with the merchant.
