1. The product ended at the end of May 2
The technology of "brittle encryption and anti-counterfeiting of laser A4 trademark" was adopted, which is characterized by:
a."A4 "has three layers of radial rings rotating in opposite directions.
B. The word "tech" is surrounded by a clear and exquisite pattern drawn by a computer and passes through a radial halo.
C. Use a laser pen to illuminate the rotating halo of "A4" inner layer from a certain angle on the right, hold a piece of light-colored paper with good transparency with your left hand and keep a certain distance above the trademark. On the paper, you will see the "Double Flying Swallow" mark that is refracted and encrypted by laser.
D. Tear off the anti-counterfeiting trademark sticker quickly, which will destroy the sticker and make the words "A4 genuine" appear brittle and encrypted.
second, because counterfeit products also adopt the above-mentioned A and B anti-counterfeiting features (which belong to surface anti-counterfeiting), it is difficult for non-professionals to distinguish authenticity. Based on this, since June, 2, a new "code anti-counterfeiting" technology has been adopted:
1. On the front of the color box, there is a rectangular small piece of "code anti-counterfeiting of this product".
(Note: OK series 2D products are accompanied by a small advertising color page with "code anti-counterfeiting" instructions. )
2. On the bottom of the mouse, there is a circular sticker with the trademark "A4":
A. Uncover the surface of the sticker with the trademark "A4" on the bottom of the mouse, and a 2-digit mouse anti-counterfeiting ID code appears. Call the 8-8285315 toll-free number prompted on the surface, enter the 2-digit mouse anti-counterfeiting ID code according to the telephone voice prompt, and press # to end.
B. After entering the correct ID code, a system voice prompt will appear: "The product you inquired is a genuine product produced by Dongguan Zhongyu Electronics Co., Ltd., thank you for using it. This inquiry is completed. If you have any questions, please call 25-4315365. Goodbye. "
3. Each mouse has only one ID code, and each ID code can only be queried once.
third, however, counterfeit products are used to make huge profits, but their identification code is limited. When calling 8-8285315 for free, there is no such identification code at all. In order to prevent accidents, Zhongyu Company has chosen another best and most advanced "digital anti-counterfeiting" technology in system protection since September 2. It only modified the telephone number on the original basis, and the operation method is the same as voice prompt. Now, the free input telephone number of identity code is 8-8289315 and the consultation telephone number is 25-3682686.
4. While adopting the above anti-counterfeiting technologies, the following points have been maintained:
1. The color box has a bar code sign approved for filing by "China Article Coding Center" and a production standard number: Q/ZY 1-1999 with factory address, factory name and product name approved for filing by the Technical Supervision Bureau.
2. The bottom of each mouse has a product model sticker and a "qualified seal" sticker; A small advertisement "digital anti-counterfeiting" instruction is attached to the box of OK series 2D products.
3. The manufacturing technology of the exterior and interior of the mouse is very fine, and there is no trace of shoddy work: the trademark printing of the mouse shell is clear and bright, and there is no shadow and fuzzy raw edges; The combination of plastic products is rigorous and the seams are even; The parts of the circuit board are arranged in a standardized way, standard solder spots are adopted, and the board body is neat and clean; The head of the mouse connecting cable is engraved with "A4" pattern, and each copper core wire inside the wire has nylon wire to increase tensile strength.
4. Exquisite packaging: the pattern imaging of color boxes, brochures, color pages and small advertising pages (especially the dot imaging of mouse patterns) is smooth and delicate, with layered colors and no darkness, high definition, no color spots and color lines, and the printed fonts are clear and unambiguous.
5. No matter how fake it is, it has no advanced production technology and strict quality control, and its products can only be rough, low in function, short in life and even carry viruses. Apart from the help of the above aspects, the most intuitive way to identify fakes is to look at the appearance (including plastic, trademark printing and outer packaging), and looking at the outer packaging is the most intuitive. Because the fake color boxes, brochures, color pages, etc. are all taken by pirated photos, the printed effect is far from the real one, and there will be spots, color lines, color distortion, blurred fonts and other phenomena, just like the color of a color TV set is not well adjusted, neither thick nor light; The pirated version can't keep up with the speed of the original revision, and there are often inconsistencies between internal and external configurations. In a word, as long as we are vigilant, take a closer look and be careful about fakes, no matter how good the fakes are, there is nowhere to follow.
VI. According to the market survey, Zhongyu Company now declares:
All products that are still using "laser A4 trademark anti-counterfeiting" should be suspected as fakes. Attention, please.
