An interactive ID system enables dynamic delivery of content to a mobile device of a person on a campus. The system includes an interactive ID server coupled to receive a tag ID of a near field communication (NFC) tag and a reader ID of an NFC reader in communication with the NFC tag, in which one of the NFC tag and the NFC reader is on the mobile device and either the tag ID or the reader ID is associated with the person. The interactive ID server determines and communicates the content provided to the mobile device.
