The invention relates to a system and a method for storing and reading information with a data storage medium for storing a piece of information and a reading unit for reading the information stored in the data storage medium, where the data storage medium has a dielectric and the information is formed by the presence or absence of at least one storage electrode in the data storage medium, and the reading unit has at least one input electrode and at least one reading electrode, the information being able to be read by coupling the data storage medium and the reading unit to one another such that the input electrode and the storage electrode form a first capacitor and the reading electrode and the storage electrode form a second capacitor. In addition, the reading unit has means for producing a digital voltage step on the input electrode and means for comparing the voltage step produced on the reading electrode with a reference voltage.

Patent is granted in Europe and China.
