发明名称 Code reader and method
摘要 A method for reading a code, which code comprises code elements and the first part of the code elements is substantially conductive and the conductivity of the second part is substantially different from that of the first part, in which method the reader couples to the code in a capacitive manner, in which case the signal level of the signal formed by the reader varies according to the conductivity of the code element, and a correction factor is determined of at least one code element for correcting the signal. ln addition, the invention relates to a code reader and electric ink.
