A housing (e.g., a wearable structure) includes one or more sensors operative to capture sensor data and a plug operative to electrically communicate data (e.g., the sensor data) to another device via a hard wired connection. A wirelessly enabled cap may be removably coupled with the housing and may include: a cavity operative to house the plug; a RF chip disposed within the housing; and one or more antennas electrically coupled with the chip. The chip is operative to wirelessly communicate data (e.g., the sensor data) in accordance with one or more wireless communication protocols (e.g., short-range, long-range, near field). The one or more antennas may form an exterior portion(s) of the housing and/or may be embedded in a portion(s) of the housing. The chip may be passive powered from an external RF source (e.g., an externally generated RF signal electrically coupled with the chip through one or more antennas).
