a power circuit configured to convert the first wireless signal into electronic power;
a circuit configured to receive the electronic power and to send a second wireless signal in response to the first wireless signal;
a first switch configured to control operation of the circuit under control of a user; and
a second switch configured to control operation of the circuit under control of the user.
2 . The switchable RFID device of claim 1 , wherein the circuit includes a single RFID tag.
3 . The switchable RFID device of claim 1 , wherein the first switch and the second switch are configured for entering a personal identification number or password into the switchable RFID device.
4 . The switchable RFID device of claim 1 , wherein the circuit includes a plurality of RIFD tags.
5 . The switchable RFID device of claim 1 , wherein the first switch is further configured for ensuring the security of a financial transaction.
6 . The switchable RFID device of claim 1 , wherein the first switch is further configured for selecting a financial account.
7 . The switchable RFID device of claim 1 , wherein the first switch and the second switch are configured to control different RFID tags.
8 . The switchable RFIID device of claim 1 , wherein the first switch is configured to change the RFID tag between a first active state and a second active state.
9 . The switchable RFID device of claim 1 , wherein the first switch is a mechanical switch.
10 . The switchable RFID device of claim 1 , wherein the circuit is included in a financial card.
11 . The switchable RFID device of claim 1 , wherein the circuit is included in a remote control.
12 . The switchable RFID device of claim 1 , wherein first switch is a membrane switch.
13 . The switchable RFID device of claim 1 , wherein first switch is disposed along an edge of the switchable RFID device.
14 . The switchable RFID device of claim 1 , wherein the first switch is disposed at least partially within the antenna.
15 . A method of operating an RFID device, the method comprising:
operating a first switch and a second switch in order to enter data into the RFID device, the first switch and the second switch being included within the RFID device;
receiving a wireless signal from an RFID reader;
generating electrical power from the wireless signal; and
using the electrical power to generate a response signal, the response signal being responsive to the data.
16 . The method of claim 15 , wherein the first switch and the second switch are configured for entering a personal identification number or password into the RFID device.
17 . The method of claim 15 , wherein the first switch is configured for selecting a financial account.
18 . The method of claim 15 , wherein the first switch is further included in a communication device.
19 . The method of claim 15 , wherein the first switch is included in a remote control.
20 . An RFID device comprising:
a plurality of RFID tags;
at least one mechanical switch configured to select between the plurality of RFID tags;
an antenna configured for sending an RF signal from the plurality of RFID tags; and
a circuit configured to generate power for sending the RF signal, the power generated from a wireless signal.
