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

1. The product is valid as of the end of May 2000

It adopts "laser A4 trademark brittle encryption anti-counterfeiting" technology, its characteristics are:

a. There are three radial halos outside "A4" that rotate in opposite directions to each other.

b. The word "TECH" is surrounded by clear and exquisite computer-drawn patterns and passes through a radial halo.

c. Use a laser pen to illuminate the rotating halo inside the "A4" from a certain angle on the right, hold a piece of light-colored paper with good transparency in your left hand and place it directly above the trademark and keep a certain distance. You will see the laser-encrypted "Shuangfeiyan" mark reflected on the paper.

d. Quickly peel off the anti-counterfeiting trademark sticker, which will destroy the sticker and cause the brittle and encrypted "A4 Authentic" words to appear.

2. Since counterfeit products also adopt the above-mentioned anti-counterfeiting features a and b (which are superficial anti-counterfeiting), it is difficult for non-professionals to distinguish the authenticity. Based on this, starting from June 2000, a new "electrical code anti-counterfeiting" technology was adopted:

1. On the front of the color box, there is a small rectangular piece with black characters on a yellow background saying "This product is anti-counterfeiting by electronic code" eye-catching logo.

(Note: OK series 2D products come with a small advertising page with "code anti-counterfeiting" instructions.)

2. At the bottom of the mouse, there is a circular printed "A4" trademark label:

a. Peel off the "A4" trademark label surface at the bottom of the mouse. A 20-digit mouse anti-counterfeiting ID code will appear. Call the toll-free number 800-8285315 prompted on the surface. According to The phone voice prompts, enter the 20-digit mouse anti-counterfeiting identity code, and press # to end.

b. After entering the correct ID code, the 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 your use. This inquiry is completed , if you have any questions, please call the consultation hotline 025-4315365, goodbye. ”

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

3. However, in order to make huge profits, counterfeit products also use "code anti-counterfeiting" technology, but their identity codes are limited. When calling 800-8285315 toll-free to inquire, there is no such identity code at all. . In order to prevent accidents, Zhongyu Company has selected another "digital anti-counterfeiting" technology that is the best and most advanced in system protection since September 2000. It only modified the phone number and the operation method on the original basis. Like the voice prompts, the current free ID code entry phone number is 800-8289315 and the consultation phone number is 025-3682686.

4. While using the above anti-counterfeiting technologies, the following points are maintained:

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

2. There is a product model sticker and a "Quality Inspection and Seal" sticker on the bottom of each mouse; the packaging box of OK series 2D products comes with a small advertisement "Digital Anti-Counterfeiting" instructions for use.

3. The manufacturing process of the exterior and interior of the mouse is very fine, and there is no sign of shoddy workmanship: the trademark printing on the mouse shell is clear and smooth, without double shadows and blurred edges; the plastics are rigorously assembled and the seams are even; the parts of the circuit board are The arrangement is standardized, standard solder points are used, and the board body is neat and clean; the head of the mouse connection cable is engraved with an "A4" pattern, and each copper core wire inside the cable has nylon wire to increase the tensile strength.

4. Exquisite outer packaging: the pattern imaging of the color box, instructions, color pages, and small advertising pages (especially the dot imaging of the mouse pattern) is smooth and delicate, the colors are layered, not dark, and the definition is high. There are no color spots or color lines, and the printed fonts are clear and not blurry.

5. No matter how fake products are copied, they do not have advanced production technology and strict quality control. Their products can only be rough, have low functions, have a short lifespan, and even carry viruses. When we want to identify fakes, in addition to the help from the above aspects, the most intuitive way 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, manuals, color pages, etc. are all photographed by pirates, the printed effect is very different from the real thing. There will be spots, color lines, color distortion, blurred fonts, etc., just like the color of a color TV that has not been adjusted. It doesn’t matter whether it’s good, strong or light; and the replicas can’t keep up with the speed of revisions of the real ones, and there are often inconsistencies in internal and external configurations. In short, we only need to be more vigilant about fakes, take a closer look, and be more careful. No matter how good the fakes are, there is nowhere to follow them.

6. Based on the market survey, Zhongyu Company now declares:

Any products that still use "laser A4 trademark anti-counterfeiting" should be suspected of being fake. Please take note.
