A server and rack system includes at least one server rack; multiple server slots within the rack; multiple near field communication (NFC) tags; a server located within one of the server slots; an NFC reader within and powered by the server; and an entity that needs to receive locations of servers within racks of the system. Each of the multiple NFC tags is positioned on the rack so as to individually correspond, on a one-to-one basis, with each of the multiple server slots, and each of the NFC tags is programmed with an identifier of the specific rack and slot with which it corresponds, and the NFC reader is positioned such that, when power is supplied to the NFC reader by the server, the NFC reader will read the identifier that corresponds to the slot the server is located within and automatically communicate that identifier to the entity.
