Sonal Surana of Commonwealth Bank of Australia (CBA) describes how the bank scaled H2O's Document AI into a production capability processing millions of documents a day, four months after early access. The talk walks through concrete use cases: extracting data from payslips and bank statements for credit assessment, reading and verifying customer ID documents like passports and driver's licenses for KYC, and automating invoice processing for accounts payable. It closes with a live demo of signature detection and forgery comparison, run against a CBA colleague's own signature as a test case.
