The .NET OCR SDK supports the Bank Account Details API.

Using the sample below, we are going to illustrate how to extract the data that we want using the OCR SDK.

Quick-Start

using Mindee;
using Mindee.Input;
using Mindee.Product.Fr.BankAccountDetails;

string apiKey = "my-api-key";
string filePath = "/path/to/the/file.ext";

// Construct a new client
MindeeClient mindeeClient = new MindeeClient(apiKey);

// Load an input source as a path string
// Other input types can be used, as mentioned in the docs
var inputSource = new LocalInputSource(filePath);

// Call the API and parse the input
var response = await mindeeClient
    .ParseAsync<BankAccountDetailsV2>(inputSource);

// Print a summary of all the predictions
System.Console.WriteLine(response.Document.ToString());

// Print only the document-level predictions
// System.Console.WriteLine(response.Document.Inference.Prediction.ToString());

Output (RST):

Field Types

Standard Fields

These fields are generic and used in several products.

BaseField

Each prediction object contains a set of fields that inherit from the generic BaseField class.
A typical BaseField object will have the following attributes:

• Confidence (double?): the confidence score of the field prediction.
• BoundingBox (BoundingBox): contains exactly 4 relative vertices (points) coordinates of a right rectangle containing the field in the document.
• Polygon (Polygon): contains the relative vertices coordinates (Polygon extends List<Point>) of a polygon containing the field in the image.
• PageId (int?): the ID of the page, always null when at document-level.

Note: A Point simply refers to a List of double.

Aside from the previous attributes, all basic fields have access to a custom ToString method that can be used to print their value as a string.

StringField

The text field StringField extends BaseField, but also implements:

• Value (string): corresponds to the field value.
• RawValue (string): corresponds to the raw value as it appears on the document.

Specific Fields

Fields which are specific to this product; they are not used in any other product.

Basic Bank Account Number Field

Full extraction of BBAN, including: branch code, bank code, account and key.

A BankAccountDetailsV2Bban implements the following attributes:

• BbanBankCode (string): The BBAN bank code outputted as a string.
• BbanBranchCode (string): The BBAN branch code outputted as a string.
• BbanKey (string): The BBAN key outputted as a string.
• BbanNumber (string): The BBAN Account number outputted as a string.
