Abstract: A product exchange system includes a controller and a memory coupled to the controller. The controller is configured to provide an interface configured to receive a request from a first user for purchase of an item; assign a unique transaction code to a transaction associated with the request, wherein a plurality of parties scans the unique transaction code during a process of the transaction; receive a notification in response to the scanning of the unique transaction code by one of a plurality of parties; and trigger an action, upon receipt of the notification, in connection with the one of the plurality of parties.

Abstract: A product exchange system comprising a controller and a memory coupled to the controller. The controller is configured to: provide an application programing interface configured to receive a delivery request from a first user for delivery of an item, wherein the delivery request includes an identifier of a second user, and wherein the API is configured not to receive a physical address of the second user; in response to receiving the delivery request, access a data storage system that stores an association between the identifier and the second user, and further stores one or more permission settings associated with the second user defining delivery requests to allow in response to receipt of the identifier from the first user or in response to receipt of one of the item and product characteristic; and, in response to receipt of the delivery request, tests the permission settings.

Abstract: The present disclosure provides systems and methods for an address exchange system including a controller configured to provide an API configured to receive an identifier from a user and further configured not to receive a physical address from the user, wherein the user provides an item for shipment to the physical address. In response to receiving the identifier, the controller is further adapted to calculate a maximum cost of the item, including one or more of a maximum sales tax and maximum shipping cost. The systems and method receive payment for the maximum cost and then refund the difference between the maximum cost and actual cost after the item has shipped.

Abstract: The present disclosure provides systems and methods for an address exchange system including a controller configured to provide an API configured to receive an identifier from a user and further configured not to receive a physical address from the user, wherein the user provides an item for shipment to the physical address. In response to receiving the identifier, the controller is further adapted to request the physical address from a data storage system wherein the data storage system stores an association between the identifier and the physical address and further stores one or more permission settings defining situations in which the physical address is to be provided in response to receipt of the identifier. In response to receipt of the identifier, the data storage system tests the permission settings to determine whether or not to provide the associated physical address.
