Document Intelligence credit card model

  • Article

This content applies to: checkmark v4.0 (preview) checkmark

The Document Intelligence credit/debit card model uses powerful Optical Character Recognition (OCR) capabilities to analyze and extract key fields from credit and debit cards. Credit cards and debit cards can be of various formats and quality including phone-captured images, scanned documents, and digital PDFs. The API analyzes document text; extracts key information such as Card Number, Issuing Bank, and Expiration Date; and returns a structured JSON data representation. The model currently supports English-language document formats.

Automated card processing

Automated Credit/Debit card processing is the process of extracting key fields from bank cards. Historically, bank card analysis process is achieved manually and, hence, very time consuming. Accurate extraction of key data from bank cards s is typically the first and one of the most critical steps in the contract automation process.

Development options

Document Intelligence v4.0 (2024-02-29-preview) supports the following tools, applications, and libraries:

  • For PDF and TIFF, up to 2000 pages can be processed (with a free tier subscription, only the first two pages are processed).

  • The file size for analyzing documents is 500 MB for paid (S0) tier and 4 MB for free (F0) tier.

  • Image dimensions must be between 50 x 50 pixels and 10,000 px x 10,000 pixels.

  • If your PDFs are password-locked, you must remove the lock before submission.

  • The minimum height of the text to be extracted is 12 pixels for a 1024 x 768 pixel image. This dimension corresponds to about 8-point text at 150 dots per inch (DPI).

  • For custom model training, the maximum number of pages for training data is 500 for the custom template model and 50,000 for the custom neural model.

    • For custom extraction model training, the total size of training data is 50 MB for template model and 1G-MB for the neural model.

    • For custom classification model training, the total size of training data is 1GB with a maximum of 10,000 pages.

Try credit card data extraction

To see how data extraction works for the Credit/Debit card service, 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 Credit/Debit Card.

  2. You can analyze the sample tax documents or upload your own files.

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

Field extraction

The following are the fields extracted from a contract in the JSON output response.

Name Type Description Example output
CardNumber String A unique identifier for the card 4275 0000 0000 0000
IssuingBank String The name of the bank that issued the card Woodgrove Bank
PaymentNetwork String The payment network that processes the card transaction VISA
CardHolderName String The name of the person who owns the card JOHN SMITH
CardHolderCompanyName String The name of the company that the card is associated with Contoso, Ltd.
ValidDate Date Valid from date 01/16
