Problems solved by technology

If all resistances are within predetermined limits, the ticket is accepted, while even one deviation can result in rejection
[0007] With many measuring electrodes, the 'digital' method occupies a large surface area on the object to be measured, while the reading device becomes complicated
Because the form of measurement takes place at close range, the resistance must be located precisely on the actual printed product, and lottery applications cannot be easily applied to other areas of use, such as post office sorting

Embodiment Construction

[0030] According to FIG. 1 , the resistor marking 6 is formed by two electrodes 2 and 3 and a resistor 1 situated between them. The attached electrodes show a test version, which has dimensions 1 x 2 cm 2 electrodes 2 and 3. The distance between electrodes 2 and 3 is 2 cm. The resistance 1 of the code resistance 6 used varies between 150KΩ-3MΩ. Based on the test, it can be observed that the working resistance value is 150KΩ-2MΩ, so the optimal measurement frequency is about 250kHz. This applies to measurements performed across 5 copies of paper, ie measuring distances < 1 mm. Output and printing technology methods can be used on for example a paper base to produce code markings according to the drawings. Combinations of printing and output technologies are also possible.

[0031] If the circuit capacitance is reduced, for example by increasing the measuring distance, or by reducing electrodes, it is worth increasing the measuring frequency. The frequency can also be incre...

Abstract

This publication discloses a method for identifying items, such as sheets of paper, or packages, a resistance mark arrangement, and reading apparatus. According to the method a mark made of electrically conductive material on the item is read contactlessly, in order to identify the item (7), or determine its properties. According to the invention, the precise absolute or relative resistance value of at least one electrically conductive mark (6) is determined and the measured resistance value is converted, for example, with the aid of a coding table or calculation formula, into information depicting the identity or properties of the item.

Description

technical field [0001] According to the preamble of claim 1, the invention relates to a method for reading a resistance marking. [0002] The invention also relates to a system for determining tagged content. Background technique [0003] According to the prior art, the output of products and documents printed using a printing press is marked with a barcode. In addition to their many good properties, barcodes also have negative properties. They are large, so they can visually interfere with the document. Furthermore, in order to read them, direct visual contact is required, in other words they cannot be read through envelopes, for example. [0004] There are also known remotely readable radio frequency tags consisting of electronic circuits which use an external energy source, such as a battery, or the radio frequency energy source of the read zone as a power source. Using these tags allows complex coding systems to be implemented because of the intelligence contained wi...
