A thin client may be utilized to facilitate data exchanges between two devices (e.g., a remote computer and a portable device). In some embodiments, the two devices may utilize differing communications protocols. The thin client may further be configured with a rules engine that determines one or more actions to be performed in response to one or more stimuli. The thin client may manage the processing flow between the two devices according to one or more predefined rules that are interpretable by the rules engine. The rules may be pushed to the thin client via any suitable device enabling the functionality of the thin client to be configured and/or modified without having to update the hardware and/or software of the thin client.
