Why Security is Crucial for Robust Payment Gateway Software Development

Payment gateway software development requires following security standards and protocols since it is crucial to protect sensitive financial and personal information for any financial app.

  • Multi-factor authentication

    Protect your customers’ online accounts with additional security through multi-factor authentication. With this feature, users undergo two or more forms of identification, such as a password and a fingerprint. It allows the prevention of unauthorized access and protects sensitive information.

  • Configurable data-level permissions

    Control your data distribution via configurable data-level permissions. This feature allows businesses to specify who can access and modify the chosen information. Data-level permissions are one of the best ways to ensure that sensitive information is only accessible to authorized users.

  • Role-based access control

    Keep your organization secured with digital role-based access control. Assign different levels of access based on employees’ roles and responsibilities. Provide employees with data crucial to perform their job duties, reducing the risk of unauthorized access and data breaches.

  • Payment data encryption

    Encrypt payment data during transmission and storage, and enable additional data protection. This can help you ensure your compliance with GDPR. Protect your customers' payment information with payment data encryption.

  • Customer data retention and deletion policies

    Maintain customer privacy with customer data retention and deletion policies. These policies specify how long customer data is retained, as to when and how it’s deleted. Ensure your customers’ safety and comply with data privacy regulations such as GDPR and CCPA.
