Scaling Customer Identity Resolution from Batch Processing to Real Time

An AAA-rated, diversified NBFC in India and the country's 3^rd largest in its category. The company approached Posidex through a group technology partner to implement real-time customer identity resolution to support growing transaction volumes and accurate customer onboarding.

‍

• Customer deduplication happened a day later, rather than during onboarding.
• The existing system could not deliver the required accuracy and throughput at scale.
• The business needed reliable matching to identify potential duplicate customers in real time.
• The NBFC needed to cross-reference both record types to establish a unified customer identity.

‍

Posidex deployed a real-time deduplication platform for both customer and contract records. Using fuzzy matching and cross-referencing logic, the platform identified potential duplicate customers during onboarding and generated a Unique Customer ID (UCIC) in real time.

The UCIC is then pushed back to the source systems, helping maintain consistent customer identities across connected workflows.

‍

• 10× increase in daily throughput: scaled from 10,000 to 100,000 transactions per day.
• 2 Cr+ customer base: supported identity resolution across a large customer base.
• Real-time: removed customer and contract checks from T-1 batch processing to at the point of onboarding, with instant UCIC generation.

With real-time customer ID in place, the NBFC can onboard customers at scale while maintaining consistent identities across customer and contract records. This creates faster lending workflows, more reliable customer data, and scalable growth as transaction volumes increase.
