Look at the barcode to distinguish fake goods from genuine goods
(Baonghean.vn) - The traditional Tet holiday is approaching, shopping demand is increasing dramatically. In that context, fake and counterfeit goods are mixed in a lot. So how to distinguish fake and counterfeit goods from genuine goods?
Almost every item has a barcode, if any item doesn't have a barcode then be careful it's most likely a fake.
We will identify real and fake products by looking at the barcode, this method is absolutely 100% correct.

There are 2 types of barcodes: 8-digit barcodes and 13-digit barcodes. These numbers will tell us everything about the product. 8-digit and 13-digit barcodes have the same identification method.
We should remember this saying, it's very simple and easy to remember: "Even times three plus odd" then add the last number, if the sum ends with 0 it's real, if it's different from 0 it's fake, very easy to remember!
1st:To know the origin of the item, we just need to look at the first 3 digits of the barcode. For example, if the first 3 digits are 893, we know immediately that this item is made in Vietnam. If it is 690, 691, 692, 693, it is from China, 880 is from Korea, 885 is from Thailand.

Looking at the picture above, I see 893 and know right away this is a Vietnamese product.

| Chinese product barcodes |
If it is 690, 691, 692, 693 like the picture, it is a Chinese product.

| Korean product barcode |
And this is 880, definitely Korean product
Monday:Once you know where it comes from, consider whether it is genuine or fake.
We take the sum of the even digits multiplied by 3 plus the sum of the odd digits (except the 13th number, the 13th number is the number to check and compare)
For example, we will calculate whether the Korean barcode above is genuine or not.
Sum of odd numbers (except the last number): A=8+0+0+3+5+4 = 20
Sum of even numbers: B=8+9+1+3+0+2=23
Now we get: C=A + B*3 = 20+ 23*3= 89
Then I take this number plus the 13th number. If this number ends with 0, then it is genuine. If the end of this sum is different from 0, then it is definitely fake or counterfeit.

Next D= C + 1 (the number in the last position) = 89+1=90, this number ends with 0 so I can conclude that this is a genuine product.

Some people wonder why counterfeiters don’t also counterfeit the barcode of the real product. The answer is that they would never dare to counterfeit the barcode because the genuine company would immediately sue the counterfeit company for stealing and copying the barcode. Therefore, the barcode is always correct and cannot be counterfeited.
And why is it that when even numbers are multiplied by three plus odd numbers and then added to the last number, the number ending in 0 is genuine? Why is this formula always correct? Because this is an international convention, called EAN.
