Non Functional Requirement
Non-functional requirements for a payment middleware (opuspay), which acts as a bridge between different systems and the payment processing infrastructure needs to follow below.
Security: The payment middleware should implement robust security measures to protect sensitive data during the payment process. It should support encryption protocols, secure communication channels, and comply with relevant security standards and regulations (e.g., PCI DSS).
Reliability: The middleware should be highly reliable, ensuring that payment requests are processed accurately and consistently. It should minimize errors, interruptions, and system downtime to maintain a smooth payment flow.
Performance: The payment middleware should be capable of handling a high volume of payment requests efficiently and with low latency. It should have sufficient processing power, memory, and network bandwidth to handle peak loads without significant performance degradation.
Scalability: The middleware should be scalable to accommodate increased transaction volumes and growing user demands. It should be able to handle increased load by adding resources or scaling horizontally without impacting performance or reliability.
Compatibility: The payment middleware should be compatible with various payment gateways, processors, and financial systems. It should support standard payment protocols and formats to ensure seamless integration with different payment service providers and platforms.
Flexibility: The middleware should be flexible and configurable to support different payment methods, currencies, and transaction types. It should accommodate customization requirements and allow for easy integration with existing systems and workflows.
Audit-ability: The payment middleware should have auditing capabilities to track and log payment-related activities. It should record transaction details, errors, and system events for troubleshooting, reconciliation, and compliance purposes.
Compliance: The payment middleware should comply with relevant financial regulations and industry standards. It should support compliance with data protection laws, anti-fraud measures, and transactional regulations specific to the regions or industries it operates in.
Integration: The middleware should support seamless integration with various systems and applications, including e-commerce platforms, point-of-sale (POS) systems, and customer management systems. It should provide well-defined APIs and data exchange mechanisms to facilitate data flow and synchronization.
Disaster Recovery: The middleware should have robust backup and disaster recovery mechanisms to ensure business continuity in the event of system failures, natural disasters, or other disruptions. It should have data redundancy, backup procedures, and failover capabilities to minimize downtime and data loss.
Localization: system needs to be compatible with local specifics
Usability: System needs to be easy to use.
Data Capacity: The payment middleware should have sufficient storage capacity to handle the volume of payment-related data it needs to store. This includes transaction records, payment details, user information, and any additional metadata required for reporting or auditing purposes. The capacity should be able to accommodate current needs and allow for future growth.
Backup and Recovery: The payment middleware should have robust backup and recovery mechanisms in place to safeguard payment data. It should support regular backups, incremental backups, and automated recovery processes to minimize data loss and facilitate business continuity.
Data Retention and Archiving: The storage solution should support appropriate data retention and archiving policies for payment-related information. It should allow for the retention of transaction history and other relevant data for auditing, dispute resolution, and reporting purposes.
Accessibility: The storage system should provide reliable and accessible storage for the payment middleware. It should ensure that authorized users can retrieve and update payment data efficiently, with appropriate access controls in place to protect data confidentiality and integrity.
Disaster Recovery: The payment middleware should have a disaster recovery plan that includes storage replication or offsite backup strategies. It should ensure that payment data can be restored and accessed in the event of a catastrophic failure or disaster.
UI Consistency: opuspay should maintain UI consistency within the system
These non-functional requirements are essential for a payment middleware (opuspay) to ensure secure, reliable, and efficient payment processing while seamlessly integrating with different systems and payment service providers.
