Abstract
The present application presents example data routing methods and apparatuses for reducing the amount of nonvolatile memory required to store secure element application locations associated with a near-field communications device. For example, the present disclosure presents a method of communication routing in a near-field communication device, which can include receiving, at a near-field communications controller (NFCC), a routing request message (e.g. from a requesting device), wherein the routing request message includes an original application identifier (AID) associated with an application. The example method may also include generating a compressed AID by applying a hash function to the original AID, reading an entry corresponding to the compressed AID in a routing data structure, wherein the entry contains one or more secure element pointers associated with one or more secure elements, and querying at least one of the secure elements to determine whether each contains the application.
