Abstract: Improved systems and methods are described for improving patient care, safety, and workflow. In particular, a rewritable identification device is provided. In some examples, identification data is exchanged between an identification device and a bidirectional device. At the outset, the identification device may receive a request for identification data from the bidirectional device. In response to the request, the identification device may retrieve the requested identification data as well as supplemental data associated with the identification data. After retrieval, the identification device may transmit, within an ultra-high frequency range, a radio frequency identification tag containing the requested identification data and the supplemental data to the bidirectional device.
