From another perspective, payment solutions are eCommerce services that verify and approve (or, if necessary, reject) the transfer of funds between buyers and sellers through various payment methods, such as bank transfer or card payment. We should not confuse them with wallets (such as Apple Pay or Google Pay), which are limited to enabling payment management between individuals or businesses.
They are important because, in addition to providing a great payment experience for customers, they can help significantly reduce credit card fraud within eCommerce. Specifically, payment solutions act as intermediaries that ensure customer data is encrypted and secure.
