Counterfeit check methodologies

When cracking down on check fraud, more attention is paid to whether the form of the check itself is difficult to imitate and whether cutting-edge technologies such as chemical methods have been applied. However, once a check has been produced using a production method, the cheque printing method is barely noticed. Printing a check using a 9-pin, high-speed dot-matrix printer or laser printer is very common, and removing the payee and data information on the check is also a simple matter. Fraud in South Africa is a chronic problem. According to official statistics, the total amount of fraud in the country exceeds the gross domestic product, and the overwhelming majority of them are fraud checks. The danger of check fraud is very large. Criminals intercept them during the check transfer process, and then change the payee or amount information, and even both are modified, causing the parties to suffer huge losses. It is almost impossible to completely eliminate this kind of fraud, but it is feasible to take appropriate precautions to make it more difficult for fraudsters to operate. The multi-color high-security printing system developed by Cirrus-Tech Vue is the most effective in the contemporary era. One of the systems to prevent check fraud. The cheque printing method is an important step for cheque anti-counterfeiting and it needs to be combined with the anti-counterfeiting measures of the cheque itself. First, the printing method There are three methods of check printing: laser printing, ink-jet printing and pressure-sensitive printing. First of all, for laser printing, we recommend that you do not use this method because it uses an ink that is not composed of fine plastic powder. After melting, it is attached to paper to form a graphic. In the best state, the diagram The text can be scraped off by a knife or removed by freezing, and it is easy to replace it with false information using a widely used desktop laser printer. Under unfavorable conditions such as high paper humidity or incorrect laser melting temperature, the text will naturally fall off or be easily replaced by Prestik or a similar method. The method of ink jet printing is better because the wet ink will in some degree penetrate into the paper fibers (the paper surface to be used should have open pores, no gloss) and it is not easy to remove. However, it is recommended not to reverse the printing of the image, because it is so easy to operate by completely blackening the printed area and pasting it with white characters. The advantages of pressure-sensitive printing are many, but it should be noted that this method uses a carbon tape typewriter or printer, which is generally not suitable when the letters are easily moved. The use of dot matrix printing is recommended. The font is black (coarse). A higher dot density will cause the paper to undergo slight denaturation, causing the ink to penetrate into the paper fibers. The Cirrus-TechVue development technology adds color to another layer of protection: it prints through ribbons of characters. This has a dual role: any fraudulent activity must either duplicate the original effect, or it must erase all old information and replace it with new data. In the latter case, due to the lack of unique identifiers, The possibility of being discovered at the time of settlement increased. Second, the security of multi-color high-pressure printing on the sheets can also be removed by superb technical means. Therefore, the paper anti-counterfeiting technology can be applied to make it more safe, and it is a very effective measure to mix the fading background of the ink and the chemical sensitivity. Variable inks are very sensitive to any liquid, so trying to use chemical methods to transfer printed information will change the background color. Chemical sensitivity, such as the use of a substance to soak paper, when the image is exposed to the information to remove chemical substances will emit a strong fading reaction, so as to achieve the purpose of anti-counterfeiting. Third, the printed information should be printed in as large a font as possible, and as close as possible to the edge of the check. The easiest way is to print large letters and digits out of range. This preventive measure makes counterfeiting more difficult. Secondly, the amount figures should be clearly and completely expressed. For example, using English numbers is better than writing Roman numerals. Generally speaking, changing English numbers is more difficult than changing Roman numerals because more letters need to be changed and the grammar is correct. Fourth, the text anti-counterfeiting continuous letter form is better than the single-letter anti-counterfeiting effect, because the concatenated word has a continuous path, in general, it is not easy to remove without leaving any traces.
