Abstract
The invention relates to the information transmission between a data-transmitting apparatus and a read- and/or write module, in particular for the use of access control. According to the invention, data to be transmitted is represented as a digital signal by the data-transmitting apparatus, and this signal is converted into an ultra-broadband signal by way of the spread spectrum method, and capacitively and/or resistively transferred via the body of the user to the write- and/or read module.
