Hello, when planning the organization of accepting payments through the site, it is necessary to take into account the fact that there are several types of payment systems. Their differentiation largely depends on the types of means of payment with which they work. The most popular are payment cards (bank card acquiring), electronic money (e-wallets) and payment solution aggregators. If in the first two cases payment systems work narrowly and with certain payment methods - credit and debit bank cards, electronic wallets - then in the case of the latter, a full-fledged complex is provided, including bank cards, e-wallets, mobile payments, bank transfers and so on. I would recommend that you choose the pay admit payment system, in which case your customers will be able to pay in different ways and in different currencies.
