The present disclosure involves solutions for dynamically connecting a customer-owned mobile device, a cloud-based service, and one or more particular physical payment devices located at an entity. In one example, as executed at a cloud-based payment service, a unique identifier associated with a location of a mobile device of a customer is received. An entity and a first location within the entity is determined based on the unique identifier, and a particular payment device at the entity is determined. The cloud service transmits, to the particular payment device, information to be used by the particular payment device to perform the payment transaction. A second signal is transmitted to the mobile device of the customer, and includes an indication of the particular payment device at which the payment transaction is to be completed. The payment transaction can then be completed at the particular payment device.
