Engineering DocScan: Slashing Verification Time from 30 to 5 Minutes

How Team Tekkeys built intelligent OCR and document verification for Sri Lankan National Identity Cards, bank statements, and utility bills.

In Sri Lankan financial institutions, verifying customer identity cards (NICs), proof-of-billing, and multi-page bank statements has traditionally been an excruciating manual bottleneck. Employees spend 20 to 30 minutes cross-checking numbers, deciphering skew angles, and manually transcribing text.

Solving the Low-Resource Language Moat

Off-the-shelf vision OCR models routinely fail on Sinhala and Tamil characters or blurry mobile photographs. With DocScan, we engineered a dedicated multi-stage pipeline combining image de-skewing, perspective correction, and fine-tuned multilingual Vision-Language Models. The result: end-to-end customer verification slashed from 30 minutes to under 5 minutes.
