How to distinguish true from false with Shuang Yan mouse

How to identify the authenticity of "Shuangfeiyan" mouse products? Here are some ways to identify the mouse:

First, the product will expire at the end of May 2000.

Using the technology of "Laser A4 Trademark Brittle Encryption Anti-counterfeiting", its features are as follows:

A "A4" has three layers of radial rings with opposite rotation directions.

B The word "tech" is surrounded by clear and exquisite patterns drawn by computers and passes through a radial halo.

C. irradiate the rotating halo of "A4" inner layer with a laser pen from a certain angle on the right. Take a piece of light-colored paper with good transparency in your left hand and put it directly above the trademark and keep a certain distance. On the paper, you will see the laser-encrypted "Double Flying Swallow" mark refracted.

D. Rapidly tearing off the anti-counterfeiting trademark sticker will destroy the sticker, and the words "A4 genuine" with fragile encryption will appear.

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 2000, a new "code anti-counterfeiting" technology has been adopted:

1. On the front of the color box, there is an eye-catching sign "This product is coded for anti-counterfeiting", which is a small rectangle with black characters on a yellow background.

(Note: OK series 2D products are accompanied by small advertising color pages with instructions of "code anti-counterfeiting". )

2. There is a circular sticker on the bottom of the mouse with the trademark "A4":

A. Uncover the surface layer of the "A4" trademark on the bottom of the mouse, and a 20-digit mouse anti-counterfeiting identity code appears. Call the 800-82853 15 toll-free number prompted on the phone, enter the 20-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 are inquiring about is a genuine product produced by Dongguan Zhongyu Electronics Co., Ltd., thank you for using it. This survey has been completed. Please call 025-43 15365 if you have any questions. Goodbye. "

3. Each mouse has only one ID code, and each ID code can only be queried once.

Third, however, in order to make huge profits, counterfeit products also use the "code anti-counterfeiting" technology, but their identity codes are limited. When calling 800-82853 15 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 for system protection since September 2000. It only modifies the telephone number on the original basis, and the operation method is the same as the voice prompt. Now, you can enter your ID number at 800-82893 15 for free, and consult at 025-3682686.

4. While adopting the above anti-counterfeiting technology, the following points have been maintained:

1. The color box has the bar code sign approved by China Article Coding Center, and the production standard number with address, factory name and product name approved by Technical Supervision Bureau: Q/ZY 1- 1999.

2. The bottom of each mouse has a product model sticker and a "qualified seal" sticker; There is a small advertisement "Digital Anti-counterfeiting" on the box of OK series 2D products.

3. The external and internal manufacturing processes of the mouse are very fine, and there is no trace of cutting corners: the trademark printing of the mouse shell is clear and bright, and there is no shadow blur; Plastic products are tightly combined with uniform seams; The arrangement of circuit board parts is standardized, with standard solder joints, 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 in the cable has nylon wire to increase the 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, the colors are layered and not dull, the definition is high, there are no spots and color lines, and the printed fonts are clear and unambiguous.

No matter what is fake, without advanced production technology and strict quality control, the products can only be rough, low in function, short in life and even carry viruses. In addition to the help of the above aspects, the most intuitive way to identify counterfeit goods is to look at the appearance (including plastic, trademark printing and outer packaging), and the outer packaging is the most intuitive. Because of fake color boxes, brochures, color pages, etc. They are all taken from pirated photos, and 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 is not well adjusted, neither thick nor light; Piracy can't keep up with the speed of the revision of the original version, and internal and external configurations are often inconsistent. In short, as long as we are vigilant, take a closer look and be careful of fakes, even the best fakes have nowhere to follow.

6. According to the market survey, Zhongyu Company hereby declares that:

All products that are still using "laser A4 trademark anti-counterfeiting" should be suspected to be fakes. Please pay attention.
