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.
