How to send text messages to city bar codes?

Sending text messages is generally a short message number, and barcodes cannot send text messages.

You can use my search, WeChat and other apps to scan. You can usually find commodity prices and information. If you can't scan, it's usually because fewer people use the product, so the information entered by the system is incomplete.

To be clear: barcodes cannot be used as anti-counterfeiting! Don't be fooled by bad businesses. Because the general bar code information is public, anyone can copy it, so many unscrupulous merchants copy other commodity bar codes and paste them on their fakes, pretending to be genuine. The result of barcode scanning is actually the product number, and the function of APP is to query the product information corresponding to this number.

Generally, QR codes cannot be used as anti-counterfeiting basis. In one case, if the two-dimensional code information of each package of the same commodity is different (there is an encryption number, and the manufacturing cost is high), that is, the commodity number is unique (these numbers are stored in the database by the merchant, and there is a query record).

So it's best to go to formal channels to buy things, and don't buy them when you see that they are cheap.
