# Paycheck

Paycheck is an example finance application, written to demonstrate OpenBanking in a minature way. The 

application is a loan-lending application that connect customers to ease access of funds - virtul currencies

in our case.

Collection of thoughts on the proposed architecture. Very high-level abstraction

of features for our application:

- Loans

- Savings

- Rewards

- KYC

## Architectural Deep Dive

- Rewards API:

    Manages user rewards for actions like early loan repayments and credit score improvement. 

    It interacts with the Rewards API for reward issuance and redemption

- Support Service: 

    Handles user support requests and communication. It connects with the Support API to manage and resolve support tickets.

- User Management Service: 

    Handles user registration, authentication, and authorization. It integrates with the Authentication

    & Authorization Service to enforce security measures like Two-Factor Authentication and Fingerprint Lock.

- Loans Service: 

    Manages loan applications, approvals, and disbursements. It interacts with the KYC Verification API

    to ensure user identity, and with the Machine Learning Service for fraud detection.

- KYC Verification Service:

    Integrates with the KYC Verification API to verify user identities using various documents and information.

- External Utils service:

    Interfaces with external services such as banking systems, credit bureaus, and third-party APIs.

    Provide service class interfaces and integrations for XML, SOAP (I think some banks uses it not sure), of course, REST APIs, maybe some GraphQL

- Threats/Security Machine Learning Service:

    Incorporates ML models to track fraud detection, detect patterns like late-night withdrawals, and ensure secure financial transactions.

- Disputes Module:

    Handles disputes related to failed transactions and loan repayments.
