Frequently Asked Questions

Authoritative answers for Finance & Banking stakeholders and technical decision-makers.

How do you store sensitive financial credentials and personal data?

All sensitive identifiers (PAN, bank account numbers, identification tokens) are encrypted at rest using AES-256-GCM with envelope encryption. Encryption keys are managed outside the database layer with automated rotation and zero plain-text disk storage.

Can your platform generate regulatory audit reports for statutory inspectors?

Yes. The admin portal includes tamper-proof audit trails detailing every login, balance adjustment, API transaction, and admin intervention with precise timestamps, IP addresses, and cryptographic signatures.

Do you support micro-lending and automated EMI collection?

Yes. We build loan origination and loan management systems (LMS) with dynamic EMI calculation schedules, NACH/e-Mandate automated recurring debits, and automated payment gateway webhooks.
