The document describes a workflow for managing business cards in a cloud-based service: 1. Business cards are scanned and undergo OCR processing and operator input to extract text and image data. 2. The data is stored in a database and can be searched, viewed, and edited through an application. 3. The service manages over 1.5 million business cards as searchable "assets" in the cloud.
