What's the difference between high-speed card and ordinary speed card in appearance and performance? How to tell?
Analysis:
At present, there are many brands of CF cards on the market, among which SanDisk is undoubtedly one with excellent quality. So how to tell the true from the false? It's actually very simple. As long as you look at the following identification methods, you can practice a pair of "critical eyes"
At present, there are many brands of CF cards on the market, and SanDisk is undoubtedly one of them with excellent quality. So how to tell the true from the false? It's actually very simple. As long as you read the following identification methods, you can practice a pair of "critical eyes".
"golden eye" 1: Look at the card body, the real thing is pressed into two pieces!
If you look closely, you can see that the CF card of genuine SanDisk is two pieces, and traces can be seen on the side and bottom.
Therefore, if the merchant sells you a "seamless" Sandisk CF card, then your "golden eye" will play a role, and you can judge that it is definitely a "demon"-a fake.
"golden eye" 2: Look at the number, the genuine products are all under the side!
Sandisk's CF card, whether new or old, has a product number, and its position is fixed-below the side of the card body.
What needs to be explained to you is that many brands of CF cards have no product number, and some are printed on the bottom of the card body or elsewhere. Although it is not excluded that other manufacturers may print the product number on the lower side of the card body in the future, if the merchant sells you a SanDisk CF card with a number printed on the bottom or no product number, you can judge that it is absolutely fake.
"golden eye" 3: Look at the metal sheet, the bending is fake!
Through the picture, we can see that there is a metal plate on the front of the CF card, which indicates the brand and capacity information. What I want to tell you here is: First of all, all the CF card metal parts of Sandisk are straight on the left side.
Fake ones are generally curved.
Therefore, if the merchant sells you an "arc" Sandisk CF card, you can judge that it is absolutely fake.
If you use the above three identification methods when purchasing, you can identify the authenticity of SanDisk CF card and see through JS at a glance.
At the same time, checking whether there is a laser anti-counterfeiting mark on the memory card is the first step to judge the authenticity of the SanDisk memory card. Because it is not excluded that a large number of counterfeiters may forge laser anti-counterfeiting marks, it is the second step to judge the authenticity of cards by checking the uniqueness of the serial numbers of anti-counterfeiting marks on different cards sold by retailers. Of course, to be on the safe side, users can call Acer and quote the serial number of the anti-counterfeiting logo of the purchased memory card to judge the authenticity. In addition, it should be pointed out that because the number sprayed on the memory card itself is a group number, it is not unique, so it cannot be judged by this.
Because the manufacturing, transportation and sales costs of counterfeit SanDisk memory cards are low, the prices on the market are relatively cheap. However, due to the inherent shortcomings of the fake card, it is very different from the real card in stability and transmission speed. Therefore, users must not be greedy and cheap when buying, in case they buy fakes. For parallel imports, although the quality of the card itself will not be problematic, because it is not a product of Acer, it cannot enjoy the warranty commitment of SanDisk. As one of the few well-known brands in the global brand memory industry, Kingston, like other famous brand products, is inevitably harassed by counterfeit goods from time to time. As a well-known brand, the biggest advantage that distinguishes it from other similar products in the market lies in its excellent after-sales service and excellent product quality. Therefore, consumers who are unfortunate enough to buy fake Kingston products lose not only economic benefits, but also reliable guarantee for after-sales service and quality assurance. Therefore, only by choosing genuine Kingston products can we obtain reliable quality assurance from Kingston Technology Company of the United States.
In order to help consumers identify the authenticity of Kingston products more intuitively, Kingston recently launched its latest color-changing anti-counterfeiting label around the world. The new anti-counterfeiting label adopts the patented SecureShift anti-counterfeiting technology provided by American Flix Company (JDS Uniphase Company, NASDAQ: JDSU), which is similar to the anti-counterfeiting technology used in currency manufacturing, and can produce a unique visual effect of color change, making it easier to identify the authenticity. Consumers only need to rely on the naked eye to judge the authenticity of products very conveniently. The specific method is very simple. Come with me ... ...
The first is the anti-counterfeiting method of Kingston memory products:
Step 1, open the Kingston product packaging box, take out the Kingston memory inside, and find the product information label printed with Kingston LOGO pattern on the memory;
The second step is to make the line of sight perpendicular to the memory PCB in a well-lit place. At this time, the identification color on the color-changing anti-counterfeiting label should be rose red (as shown in the figure);
Step 3: Turn the PCB at an angle and the color will change. At this time, the observed color-changing anti-counterfeiting logo will immediately turn into olive green (as shown in the figure);
Through the above simple and easy steps, I believe that every consumer can easily identify the authenticity of the purchased Kingston memory in less than half a minute, and because of the leading edge of this anti-counterfeiting technology, there is almost no possibility of counterfeiting at present, and consumers can rest assured to buy Kingston memory with a brand-new color-changing anti-counterfeiting mark.
At the same time, Kingston's flash memory products in the domestic market also adopt this latest color-changing anti-counterfeiting label, and its anti-counterfeiting method is similar. Taking Kingston's CF card products as an example, the general identification method is as follows:
Step 1: Take out the Kingston CF card product in the package and find the words "Kingston" LOGO, "digital memory card" and "MB" on it;
Step 2: Make the line of sight perpendicular to the color-changing safety sign on the front of the CF card. At this time, the above words should be rose red (as shown in the figure):
Step 3: flip the CF card, and the word rose will change color to olive green (as shown in the figure):
Through the above simple and easy methods, Kingston provides consumers with the simplest and easy anti-counterfeiting method to identify Kingston memory, and provides an effective way for consumers to buy genuine Kingston memory with lifetime warranty. At the same time, for Kingston's memory products, the "website authentication" method started last year is still effective. Please refer to Kingston's verification website: kingston/china/verify for details.
After the end of February, 2004, all Kingston products sold in China will bear the brand-new color-changing anti-counterfeiting label of the above Kingston memory. After that, consumers can sit back and relax when they buy Kingston memory.
Kingston provides a wide range of memory products for many systems. For more information about Kingston's new color-changing safety sign, please call Kingston Company at 800-8 10- 1972 (Beijing: 0/kloc-0-8488-2188) or visit Kingston/China or Kingston's website.
