Signature Card Extraction

Introduction

The Signature Card Extraction API is designed to automatically extract key information from signature card documents submitted by users. Using OCR and document intelligence techniques, the API identifies and captures relevant fields from the signature card, converting unstructured document data into a structured JSON response.

This API helps organizations digitize signature card processing, reduce manual data entry, improve operational efficiency, and enable faster verification workflows.
