At present, there are more and more businesses in China going to Brazil to do e-commerce, foreign trade, games, media and so on. In Brazil, these businesses will involve a cross-border payment problem, that is, Brazilian users pay online or offline to e-commerce platforms or game businesses. Generally, this kind of cross-border payment needs to be paid by a third party. As far as China is concerned, only Pagsmile, a platform in the cloud, supports all credit card types in Brazilian local currency and credit cards issued by major banks in Brazil. Therefore, if a domestic company that goes to sea wants to do business in Brazil, it is best to take the payment platform pagsmile, which is the only one that has obtained the payment license in Brazil, that is to say, local banks in Brazil are authorized and Brazilian users trust it. In this way, the company has solved a big problem of payment.
