The Document Intelligence business card model combines powerful Optical Character Recognition (OCR) capabilities with deep learning models to analyze and extract data from business card images. The API analyzes printed business cards; extracts key information such as first name, surname, company name, email address, and phone number; and returns a structured JSON data representation.

Business card data extraction

Business cards are a great way to represent a business or a professional. The company logo, fonts, and background images found in business cards help promote the company branding and differentiate it from others. Applying OCR and machine-learning based techniques to automate scanning of business cards is a common image processing scenario. Enterprise systems used by sales and marketing teams typically have business card data extraction capability integration into for the benefit of their users.

Try business card data extraction

See how data, including name, job title, address, email, and company name, is extracted from business cards. You need the following resources:

• An Azure subscription—you can create one for free

• A Document Intelligence instance in the Azure portal. You can use the free pricing tier (F0) to try the service. After your resource deploys, select Go to resource to get your key and endpoint.

Document Intelligence Studio

1. On the Document Intelligence Studio home page, select Business cards.

2. You can analyze the sample business card or upload your own files.

3. Select the Run analysis button and, if necessary, configure the Analyze options :

   

   Try Document Intelligence Studio

Document Intelligence Sample Labeling tool

1. Navigate to the Document Intelligence Sample Tool.

2. On the sample tool home page, select the Use prebuilt model to get data tile.

   

3. Select the Form Type to analyze from the dropdown menu.

4. Choose a URL for the file you would like to analyze from the below options:

   • Sample invoice document.
   • Sample ID document.
   • Sample receipt image.
   • Sample business card image.

5. In the Source field, select URL from the dropdown menu, paste the selected URL, and select the Fetch button.

   

6. In the Document Intelligence service endpoint field, paste the endpoint that you obtained with your Document Intelligence subscription.

7. In the key field, paste the key you obtained from your Document Intelligence resource.

   

8. Select Run analysis. The Document Intelligence Sample Labeling tool calls the Analyze Prebuilt API and analyze the document.

9. View the results - see the key-value pairs extracted, line items, highlighted text extracted, and tables detected.
