🔐 What are Payment Service Providers (PSPs)? 🤔

Introduction

In the world of Fintech and crowdfunding platforms, the role of Payment Service Providers (PSPs) is essential. These players act as intermediaries between investors and funding platforms, ensuring that all transactions are processed smoothly, securely, and in compliance with regulatory requirements. Without PSPs, it would be difficult to ensure transaction security and adhere to the applicable laws. 📊

PSPs provide a range of services that enable investors to deposit money, project owners to receive funds, all while ensuring a secure framework. But their role goes far beyond financial transactions. Let's take a closer look at why PSPs are crucial for the proper functioning of funding platforms and how they contribute to the security of investment flows.

The Crucial Role of PSPs

PSPs are responsible for several key aspects of the financial process on crowdfunding platforms and other types of funding:

  1. KYC (Know Your Customer):
    Security first! One of the first roles of a PSP is to verify the identity of users, whether they are investors or project owners. To do this, rigorous KYC procedures are put in place. PSPs must verify identity documents, proof of life, and other elements that can confirm the user's identity. This step helps prevent fraud and ensures that transactions are carried out by legitimate individuals. 🔒

  2. Creation of Wallets:
    PSPs facilitate the management of funds by creating wallets (virtual accounts) for investors. These wallets are used to deposit money, make investments, or transfer funds between the investor's wallet and the funded projects. These virtual accounts enable seamless and fast management of investments, while maintaining a high level of security.

  3. Transaction Security:
    PSPs ensure that all transactions between investors and projects take place in a secure environment and comply with international standards such as PSD2 in Europe. In addition to ensuring payment security, PSPs also enable real-time transactions and provide complete traceability of operations.

Investment Flows: How Does it Work? 🔄

Financial transactions between investors and projects are carried out in different ways. Here's an overview of the main payment flows:

  • Pay-in:
    This term refers to the process by which an investor credits their account on the platform by transferring money from their bank account or credit card. This flow is essential to fund the investor’s wallets before they make investments in projects.

  • Pay-out:
    After investing, the pay-out refers to the debit of funds from the investor's wallet to an external bank account. This can be a refund of investment or withdrawal of earned returns.

  • P2P Transfer (Peer-to-Peer):
    This is the transfer of funds between the investor and the project. These transactions allow funds to be transferred directly from the investor's wallet to the project, creating a direct financial link.
