An RFID transponder (T) suitable for communication with a reading device (RD) and adapted to be connected to a monitored unit (MU) is provided. The RFID transponder (T) comprises a comparing unit (CU) adapted to and arranged to receive a status signal from the monitored unit (MU) and configured to compare a value of the status signal to at least one predefined reference value and a state machine circuit (STM) connected to the comparing unit (CU) and configured to determine, based on a result of the comparison, whether the value of the status signal lies outside a range of operation defined by the at least one reference value. The state machine circuit (STM) is further configured to indicate the reading device (RD) that the value of the status signal lies outside the range of operation if the value of the status signal lies outside the range of operation.

A wearable RFID device is configured with a geometry and materials that allow an HF RFID system and a UHF RFID system to operate in close proximity to a human body and to each other with minimal impact on performance. An RFID device may have a three-dimensional, multi-planar UHF antenna incorporated into a dielectric core with an HF antenna, or a single-plane UHF antenna separated from an HF antenna by a rigid spacer. A conductive metal backplane is disposed adjacent the wearable RFID device to improve antenna performance when disposed in close proximity to an absorbing body, such as a human being.
