System, method and card for user authentication and/or authorisation

A method for user authentication and/or authorization, comprising:

• providing a card having a surface that includes a matrix of capacitive points, the card further having embedded therein a controller, a time element connected to the controller, a battery for power supply the time element and the controller, and a memory storing at least one portion of at least one authentication and/or authorization code pattern for a user;
• providing, by the controller, the at least one authentication and/or authorization code pattern by activating some of the capacitive points of the matrix of capacitive points following a given transmission sequence, said transmission sequence comprising using a reference indicator as a location and/or synchronization marker and serially activating the capacitive points, wherein when the activation of the capacitive points is completed said transmission sequence is repeated;
• and
• once the card is placed in direct contact with a capacitive screen of a computing device, the computing device sensing and translating the activated capacitive points to a corresponding user authentication and/or authorization code number.

A card for user authentication and/or authorization, the card having a surface that includes a matrix of capacitive points and including, embedded therein:

• a controller,
• a time element connected to said controller,
• a battery configured to power supply said controller and said time element, and
• a memory configured to store at least one portion of at least one authentication and/or authorization code pattern for a user, the at least one authentication and/or authorization code pattern being represented through some activated capacitive points of said matrix of capacitive points,
• the controller being configured to activate the capacitive points by of executing a given transmission sequence, said transmission sequence comprising using a reference indicator as a location and/or synchronization marker, and serially activating the capacitive points, wherein when the activation of the capacitive points is completed said transmission sequence is repeated.
