Embodiment Construction

[0031] The present invention proposes an electronic circuit for interconnecting a smart card chip with peripheral devices. The electronic circuit includes a configurable communication interface for communicating with peripheral devices. The electronic circuit also includes a dedicated communication interface for communicating with the smart card and for receiving configuration requests for the configurable communication interface. Based on the received request, the configuration module configures the communication protocol of the configurable communication interface using the peripheral device.

[0032] According to the present invention, the smart card can communicate with a wide variety of peripheral devices without requiring its smart card chip to have multiple specific interfaces. The smart card is thus able to interface to peripheral devices without changing the interface of its smart card chip. It is thus possible to use very standardized smart card chips. When the sm...

Abstract

The invention relates to an electronic circuit (3) for interconnecting a smartcard chip with a peripheral device, comprising: -a dedicated communication interface (31) adapted to communicate with a smartcard chip; -a configurable communication interface (33,34,35) adapted to communicate with a peripheral device; -a configuration module (32) adapted to receive on said dedicated communication interface a request for configuring the configurable communication interface, adapted to configure the communication protocol of the configurable communication interface with the peripheral device based on the received request; -a bridging module (32) adapted for converting data exchanged between the peripheral device and the smartcard chip through the dedicated communication interface and the configurable communication interface.

Description

technical field [0001] The present invention relates generally to a smart card, and more particularly to a smart card controlling a peripheral device. Background technique [0002] Smart cards are usually plastic cards with an implantable open chip. A smart card chip is an integrated microcontroller that usually includes a central processing unit, random access memory, ROM memory, and RRPROM memory. [0003] Smart card readers must be recognized by the infrastructure before any transaction involving a smart card can be performed. The infrastructure runs an application in which the smart card is incorporated. A smart card reader expects a card reader. The half-duplex protocol between the smart card and the smart card reader does not start until the smart card is detected in place into the smart card reader, where the smart card sends information to the smart card reader or the card reader sends information to the smart card. The infrastructure manages, for example, authen...
