Abstract
Methods and apparatus for correlating physical and logical attributes of devices include associating logical-tags (L-tags) and physical-tags (P-tags) with electronic devices. A P-tag includes a P-tag identifier, which can be read by a P-tag reading device, regardless of whether power is applied to the electronic device. In one embodiment, a system includes a P-tag comprising a radio frequency identification (RFID) tag having a non-volatile memory to store physical and logical attribute information; and an electronic device associated with the RFID tag, the electronic device having a processor and a bus, and being communicatively coupled to the RFID tag over the bus, the processor to execute instructions to read information from and write information to the non-volatile memory of the RFID tag.
