Portable device for the functional linking of a chip card with a central processing unit
First Claim
1. A portable device for functionally linking a chip card with a central processing unit, the portable device comprising:
- a pack adapted for receiving the chip card;
a first wireless linking device disposed between the pack and the central processing unit, the first wireless linking device being adapted for establishing a first type of wireless communication link with the central processing unit, the first type of wireless communication link corresponding to a first application stored in the chip card;
a second wireless linking device disposed between the pack and the central processing unit, the second wireless linking device being adapted for establishing a second type of wireless communication link with the central processing unit, the second type of wireless communication link corresponding to a second application and being of a different type than the first wireless communication link;
a detector which detects the type of wireless link which enables the chip card and the central processing unit to communicate, the detection being a function of the application contained in the chip card, and the detection device being adapted to carry out a reading of an information element determining the type of wireless link to be used; and
a selector which selects one of the first and second wireless linking devices based on the type of wireless link detected, the selection thereby being a function of the application in the chip card.

Abstract
Portable chip-card readers enabling a remote link to be set up with a central processing unit. It consists in providing, in a pack, for at least two different types, radiofrequency or infrared for example, of communication with the central processing unit. These communications means are selected from the chip card or for detecting signals of the central processing unit, or from both together. An activation circuit is used, if necessary, to activate the reader only on the detection of these signals. It enables the use of a signal reader for different applications, such as permission for entry or the payment of highway toll fees.
