Methods and systems are described for picking up an order using elements of a wireless node network. In one example, a master node receives order information from a server, where the order information identifies the order and a mobile user access device registered to pick up the order. The master node detects a signal broadcast from the mobile user access device identified by the order information when the mobile user access device is operating as an advertising ID node in the network and as the mobile user access device approaches the master node. The master node then associates with the identified mobile user access device. When the master node determines the identified mobile user access device is within a predetermined range of the pickup point, the master node notifies an order management system responsible for the order.
