1. A configurable radio frequency identification (RFID) tag, comprising:
- an antenna for receiving an RFID signal;
multiple RF matching elements for operating at multiple frequency bands;
a band selector coupled to the antenna for selecting one of the RF matching elements;
a protocol selector for selecting a protocol;
a material selector for selectively tuning the RFID tag to a selected material based on an electrical or manual input from a user, wherein the selected material is a material on which the RFID tag is placed in, on, or near; and
,an RFID processor for processing the signal according to the selected protocol,wherein the band selector and protocol selector each comprises an array of manually controlled switches.

Abstract
A multi-band and/or multi-protocol, configurable, RFID tag is provided. The tag can include one or more electrical or mechanical selectors for selecting from among multiple frequency bands and communication protocols. In some embodiments, a signal band and protocol can be detected automatically and selection among bands and protocols can be performed automatically. In some embodiments, one or more externally accessibly switches can be actuated by a user to select a band and/or protocol.
