According to an aspect of an embodiment, a method may include obtaining, at a mobile biometric-data hub, a first biometric reading of a user. The method may also include, based on the first biometric reading, associating the mobile biometric-data hub with the user. The method may also include wirelessly receiving, at the mobile biometric-data hub, a second biometric reading from a biometric sensor distinct from the mobile biometric-data hub. The method may also include determining that the second biometric reading is of the user. The method may also include, based on the second biometric reading being of the user and based on the association between the mobile biometric-data hub and the user, tagging the second biometric reading with an identifier of the user. The method may also include communicating the tagged second biometric reading from the mobile biometric-data hub to a network-attached device.
