Abstract: A server exchanges information between one or more wireless devices to complete a transaction. The server receives second device identifier information from a first wireless device using a wide area network. The second device identifier information was previously provided to the first wireless device using short range wireless communication. The server then uses the second device identifier information to determine additional information concerning an entity or object located in proximity to the second device, and then the server delivers information to the first wireless device based at least in part upon both (a) the second device identifier and (b) a current step in a multiple step process for an ongoing electronic commerce transaction.

Plain-Language Overview of Independent Claims:

• Claim 1: This claim describes a method for exchanging information between wireless devices using a central server. A first device detects a unique identifier from a second device using a short-range wireless connection (like Bluetooth or Wi-Fi). Instead of communicating directly, the first device sends this detected identifier to a central server via a wide area network (like cellular data). The server then uses the identifier to find relevant information about the second device or its associated entity, applies policies to determine what information can be shared, and sends that information back to the first device. The crucial part is that the identifiers are dynamic and only the server can associate them with specific accounts over time, enhancing security and allowing for policy enforcement. The communication between devices for substantive data happens via the server over the wide area network, not directly peer-to-peer.
• Claim 12: This claim describes a system that performs the method of Claim 1. It includes a first wireless device, a second wireless device, and a central server. The first device has both a short-range radio (to detect identifiers from the second device) and a wide area network radio (to communicate with the server). The server manages user accounts, device identifiers (which can change over time for anonymity), and policies for information disclosure. The system facilitates the exchange of information and services based on proximity detection but brokered through the central server.
• Claim 23: This claim describes a server for managing information exchange between wireless devices. The server receives a detected identifier from a first device (which the first device obtained via short-range communication from a second device). The server then uses this identifier to retrieve information about the second device's associated entity or object, applies disclosure policies, and sends relevant information back to the first device. The server also manages the dynamic updating of device identifiers to enhance security and anonymity.
