In one embodiment, an apparatus includes a first assembly, a second assembly, and a coupling element coupled to the first assembly and the second assembly. The first assembly includes a processor, a memory, and a radiator module, the processor operatively coupled to the memory and the radiator module. The second assembly includes a radiator operatively coupled to the radiator module. The second assembly is movable relative to the first assembly about the coupling element between a first configuration and a second configuration. The processor is configured to interrogate a radio-frequency identification module via the radiator module and the radiator when the second assembly is in the second configuration.
