Every time I finish online shopping, I get a text message reminding me how much I should pay. Does this feature cost money?

No, there are three mainstream payment methods at present. The first is Alipay payment. I suggest you apply for a green card at the Postal Bank. I also use this service, which is very convenient. ) and it's safe. Every deposit and payment is bound with SMS password verification, which is very safe. The second form belongs to cash on delivery, that is, the merchant sends you something and the courier company delivers it to your door for a fee. This is very suitable for friends who just started online shopping, with a safety factor of 100%, and can be used as a courier to open the package for inspection. The third is the form of bank payment. There are many deceived buyers and sellers in this form, and it is recommended not to use it. I also buy some small things online, and now the postal green card is very convenient and safe.
