Method and apparatus for a USB and contactless smart card device
First Claim
1. An apparatus for a smart card, the apparatus comprising:
- an access interface including an antenna and a wired interface;
a mode detection circuit coupled to the access interface to detect a wireless communication mode and at least one wired communication mode to the smart card;
a switching block coupled to the mode detection circuit to send a set of mode operation signals based on a type of mode detected by the mode detection circuit; and
a controller coupled to the switching block and the mode detection circuit to enable operation of the smart card in a first mode based on the set of mode operation signals, and further to enable change of operation of the smart card to another mode after the first mode.

Abstract
An apparatus for a Universal Serial Bus (USB) and wireless smart card is provided. The apparatus includes a mode detection circuit, a switching block, a controller, an antenna, and a wired interface. Furthermore, an apparatus for a triple-mode smart card is also provided herein. The apparatus for the triple mode smart card includes a mode detection circuit, a switching block, a controller, an antenna, and a wired interface. The apparatus for the triple mode smart card operates in one of a wireless mode, a USB mode and an International Standards Organization 7816 mode or other wired mode. Furthermore, the apparatus for any of these smart cards could operate in both the wireless and wired mode(s) without conflict, and without switching power off and on to change configuration.

13. A method for a smart card, the method comprising:
-
determining whether a wireless signal is detected;
operating the smart card in a wireless mode if the wireless signal is detected;
operating the smart card in a wired mode if the wireless signal is not detected and if a wired connection is detected; and
automatically allowing operation of the smart card in a different mode after operating in one of either the wireless mode or the wired mode. - View Dependent Claims (14, 15, 16, 17)

18. An apparatus for a smart card, the apparatus comprising:
-
a first detection circuit to detect a wireless connection to the smart card;
a second detection circuit to detect a wired connection to the smart card;
a switching block coupled to the first and second detection circuits to generate a first signal that corresponds to a type of connection detected by one of the detection circuits; and
a controller coupled to the switching block and responsive to the first signal to allow operation of the smart card in a first mode that corresponds to the type of detected connection, and to allow the smart card to support a second mode that corresponds to a second signal provided by the switching block and to automatically transition operation of the smart card to the second mode in response to the second signal. - View Dependent Claims (19, 20)

21. An apparatus for a smart card, the apparatus comprising:
-
a means for receiving a signal sent to the smart card;
a means for determining whether the signal corresponds to a wire or wireless connection;
a means for automatically switching operation of the smart card between modes in response to the determined connection; and
a means for operating the smart card in a first mode and for supporting simultaneous operation of the smart card in a second mode, including a means for blocking detection of the second mode if the smart card is operating in the first mode and for automatically transitioning from the first mode to the second mode if the signal to the smart card changes. - View Dependent Claims (22, 23, 24)
