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.
