Medical monitoring devices may be able to read a wireless tag and determine an identity of a patient wearing the tag based on the information read from the tag. The tag may be an RFID tag, a barcode, etc. The tag may itself include identifying information for the patient, or the tag may include an identifier that allows the patient information to be retrieved from a remote storage device via a network. The medical monitoring device may also be able to retrieve configuration information using the identifier. The configuration information may include settings for the medical monitoring devices and/or may include destinations for physiological data measured by the medical monitoring devices. Destinations may organize data based on the patient and may use the patient identifiers transmitted by the medical monitoring devices to associate data from separate medical monitoring devices attached to the same patient.
