The banking industry is rapidly evolving to adopt secure and efficient methods that enhance client onboarding experiences. This project introduces a Unified Know Your Customer (KYC) Verification System aimed at automating and streamlining the account opening process for banks. Traditionally reliant on manual data entry, which is susceptible to delays and errors, KYC procedures are now reimagined using cutting-edge technologies. The proposed system integrates nationallevel APIs to authenticate key identity documents such as Aadhaar, PAN, and driving licenses. Additionally, it employs Azure Cognitive Services for Optical Character Recognition (OCR) to extract and validate data from submitted documents against official records. Upon successful cross-verification, the system generates a unique identifier (UID) for each client, enabling secure, reusable digital identities for future banking operations. This not only simplifies client access to multiple services but also enhances data integrity and regulatory compliance. The methodology ensures reduced manual workload, faster onboarding, and increased accuracy in identity verification processes. Results demonstrate improved operational efficiency and stronger adherence to Anti-Money Laundering (AML) standards. In conclusion, the Unified KYC Verification System offers a scalable, secure, and user-centric solution that transforms traditional banking processes while aligning with digital transformation goals in the financial sector.
