ABSTRACT:
A product for electronic transmission of handwritten information, a user unit for recording and sending the information, and a computer program for controlling a user unit are disclosed. The product may include at least one writing area for the handwritten information and an address area indicating an address to which the handwritten information is to be sent. A position-coding pattern in the form of a plurality of symbols may be reproduced in the writing area, an arbitrary position area of a predetermined size of the position-coding pattern unambiguously defining a position on the product. The address area may include an address-coding pattern with a plurality of symbols, an arbitrary address portion of a predetermined size of the address-coding pattern unambiguously defining part of the address.
