FIELD: information technology.
SUBSTANCE: mark has first sections lying at a distance from each other on a base, the said sections including at least one electroconductive material whose electroconductivity exceeds a given threshold value, and second sections lying between the first sections and having electroconductivity which is less than or equal to the said threshold value. According to the invention, at least two first sections are essentially distinguished from each other by electroconductivity.
EFFECT: mark provides data storage volume which is many times greater than that of existing electrical marks.
