How to identify the authenticity of Kingston USB flash drive

The method of identifying the authenticity of Kingston USB flash drive;

① Anti-counterfeiting labels (Kingston anti-counterfeiting, general anti-counterfeiting, provincial and municipal anti-counterfeiting)

At present, it is impossible to distinguish the true from the false only by the anti-counterfeiting verification behind Kingston's shell, and the fake has been completely done. So we should start with the source of goods.

It can be seen that Kingston has four agents: AVNET, Hengying Electronics, Hejun Industry and Lianqiang International. The goods on the market are generally Lianqiang International, Hengying Electronics and AVNET.

Let's take a closer look at the label status of these agents.

Lianqiang International: Rectangular Anti-counterfeiting (see the figure below for the international source of U disk Lianqiang in U disk mass production tool network DT1KLOC-0/G2 4g);

As you can see in the picture, the first small anti-counterfeiting label is the agent of Lianqiang International, and the label with the words "National Joint Guarantee" below is the anti-counterfeiting label of Lianqiang International.

Hengying Electronics: It is a paper rectangle with Hengying's 400 security code and verification phone printed on it, which looks a bit ugly (see the following figure for the supply of Hengying Electronics on the U disk mass production tool network DTI G3 8GU);

Hengying Electronic's anti-counterfeiting supports telephone and SMS verification. The small label on the left is the anti-counterfeiting of Hengying's agent (Zhongbang), which you will see below.

You can see that on the outer packaging, the label of Hengying Electronics is attached to the upper left corner.

AVNET: rectangular anti-counterfeiting, without 800 certification (products are not common, no photos are taken for the time being);

JD.COM Industry (Zanhe): At present, this product appears in the mall.

These agents are first-class agents. Under the premise of not affecting the appearance of the U disk, the anti-counterfeiting label of the first-class agent is generally attached to the U disk; First-level agents will develop agents, usually provincial and municipal agents. When the goods circulate to provinces and cities, the label of the second-level agent will be produced. So Kingston USB flash drive generally has two labels.

This identification method mainly lies in identifying whether the source of the product is formal or not.

② Appearance identification

(3) technical identification-master identification (take group connection as an example, please bypass other masters)

Tools needed: Chip Worry-Free, Chip Wizard, Group GETINFO.

When the USB flash drive can be used normally, the download chip wizard detects whether the master control is connected in groups. If yes, use the special main control detection tool for group connection for detection. If you can't read the main control information, the USB flash drive is faulty.

Use a dedicated master detection tool (GETINFO) for group association to

Under normal circumstances

Exception, device not found.

If you can't find the device through GETINFO, please try to change the USB port again. If it doesn't work, try another computer. If not, there is a problem. The device could not be found for the following reasons:

1, too many bad blocks;

2, disguised as a master, it is not a group master at all, and it is definitely not a genuine Kingston.

④ technical identification-serial number identification

Required tools: chip wizard, group connection GETINFO master control detection

Read the serial number of the device through the chip wizard; If it is the group owner, use the group GETINFO main detection tool to read SN.

As long as it is genuine and licensed in Kingston, and it is not artificially mass-produced, its SN code (serial number) must be 24 digits, of which the thirteenth letter is B, which means the group leader, A, Qingtai leader and F, the new founder. Kingston authentic licensed only uses the above three kinds of master control. If not, it is a fake. (Note: SN will become 16 bit after mass production, and cannot be restored to 24 bit).

⑤ Technical appraisal-expansion detection

Required tools: MyDiskTest, U disk tester.

Many fake USB flash drives are expanded to 2GB, 4GB and so on. Pass 1GB, but it can't be used normally after expansion. If the extension is detected by MyDiskTest, it is false.

This is a USB flash drive test result of Kingston MINI FUN, which passed the test and did not expand.

⑥ Note: General agent anti-counterfeiting labels are attached to removable U disk (such as DT 10 1G2, DTIG3, etc.). ), but it can't be attached to non-detachable packages (such as DT200, DT500, etc.). ); Software USB flash drives such as waterproof and anti-fall are generally not labeled because they are easy to fall off after being labeled.
