BSTL – Currency Management & Card Issuance Platform

BSTL is a financial platform designed to support currency management and card issuance, serving customers, third-party partners, and internal operations within a unified ecosystem. The system enables users to manage balances, perform transactions, and control card-related activities through both web and mobile applications.

The project was delivered as a one-stop service, covering design, development, and system integration to ensure a scalable and secure financial solution.

Project Overview

BSTL web

The platform was built to streamline financial operations by combining account management, card services, and transaction control into a single system. Users can monitor balances, manage cards, and perform financial actions such as transfers, withdrawals, and payment tracking in a structured and intuitive interface.

Because the system supports multiple user groups—including end users, partners, and internal teams—it required a flexible architecture capable of handling different roles, permissions, and workflows while maintaining strong performance and security.
