4. The communication system of claim 1 , wherein said smartcard is operable to:
transmit a first portion of an outgoing message via a first one of said near-field radio, said far-field radio, and said contact-based radio; and
transmit a second portion of said outgoing message via a second one of said near-field radio, said far-field radio, and said contact-based radio.
5. The communication system of claim 1 , wherein said smartcard is operable to:
transmit an outgoing message via a first one of said near-field radio, said far-field radio, and said contact-based radio; and
receive an acknowledgment of said outgoing message via a second one of said near-field radio, said far-field radio, and said contact-based radio.
6. The communication system of claim 1 , wherein said smartcard is operable to:
receive parameters via a first of said near-field radio, said far-field radio, and said contact-based radio; and
configure, based on said received parameters, one or more of: modulation, frequency, transmit levels, and encoding used by a second of said near-field radio, said far-field radio, and said contact-based radio.
7. The communication system of claim 1 , wherein:
said smartcard comprises a memory;
a first portion of said memory is only accessible via a first one of said near-field radio, said far-field radio, and said contact-based radio; and
a second portion of said memory is only accessible via a second one of said near-field radio, said far-field radio, and said contact-based radio.
8. A method comprising:
in an ISO 7816 compliant smartcard, said smartcard comprising, a memory, a near-field radio operable to communicate wirelessly, a far-field radio operable to communicate wirelessly, and a contact-based radio operable to communicate via one or more metal contacts of said smartcard:
receiving data via a first one of said far-field radio, said near-field radio, and said contact-based radio; and
transmitting said received data via a second one of said far-field radio, said near-field radio, and said contact-based radio.
9. The method of claim 8 , comprising:
transcoding said received data prior to said transmitting said received data via said second one of said far-field radio, said near-field radio, and said contact-based radio.
10. The method of claim 9 , comprising:
receiving said data via said contact-based radio; and
transmitting said transcoded data via said far-field radio.
11. The method of claim 9 , comprising:
receiving said data via said far-field radio; and
transmitting said transcoded data via said contact-based radio.
12. The method of claim 8 , comprising:
transmitting a first portion of a message via a first one of said near-field radio, said far-field radio, and said contact-based radio; and
transmitting a second portion of said message via a second one of said near-field radio, said far-field radio, and said contact-based radio.
13. The method of claim 8 , comprising:
receiving a first portion of a message via a first one of said near-field radio, said far-field radio, and said contact-based radio; and
receiving a second portion of said message via a second one of said near-field radio, said far-field radio, and said contact-based radio.
14. The method of claim 8 , comprising:
transmitting a message via a first one of said near-field radio, said far-field radio, and said contact-based radio; and
receiving an acknowledgment of said message via a second one of said near-field radio, said far-field radio, and said contact-based radio.
15. The method of claim 8 , comprising:
receiving parameters via a first of said near-field radio, said far-field radio, and said contact-based radio; and
configuring, based on said received parameters, one or more of: modulation, frequency, transmit levels, and encoding used by a second of said near-field radio, said far-field radio, and said contact-based radio.
16. The method of claim 8 , wherein:
a first portion of said memory is only accessible via a first one of said near-field radio, said far-field radio, and said contact-based radio; and
a second portion of said memory is only accessible via a second one of said near-field radio, said far-field radio, and said contact-based radio.
17. A communication system comprising:
an ISO 7816 compliant smartcard, said smartcard comprising:
