Fax OCR & Textract Prescription Workflow

The fax-based prescription approval process modernized with redesigned templates and AWS Textract OCR.

Problem
Fax prescription forms were hard to read and process, leaving pharmacy staff with manual effort and rework.
Solution
Redesigned fax templates, refactored the approval workflow and integrated AWS Textract OCR to extract structured data.

Impact

Fax forms became machine-readable, so pharmacy staff stopped re-keying and reworking prescriptions.
