Methods and devices for assigning RFID device personality
First Claim
1. A method, comprising:
- receiving a message on a network; and
automatically determining a device identity of a device configured to capture information regarding environmental changes according to a media access control (“
MAC”
) address and a product code included in the message.

Abstract
Methods and devices are provided for identifying, locating and provisioning individual RFID devices in a network with “personalities” that are appropriate for the roles of the RFID devices. According to some implementations of the invention, a combination of EPC code information and existing networking standards form the basis of identifying and provisioning methods. For example, MAC address information and EPC information can be combined to identify a particular device and its location in a network. For implementations using the Dynamic Host Configuration Protocol (“DHCP”), DHCP Options may be used to pass provisioning information. Some implementations employ Domain Name Service (“DNS”) and dynamic DNS (“DDNS”) to allow easy identification of RFID devices.

13. A method, comprising:
-
forming a DHCPDISCOVER request that includes an electronic product code (“
EPC”
) of a device;sending the DHCPDISCOVER request to a Dynamic Host Configuration Protocol (“
DHCP”
) server; andreceiving provisioning information from the DHCP server that corresponds with the EPC, the provisioning information enabling a functionality that corresponds with a device identity. - View Dependent Claims (14, 15, 16)
