The Ruby 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.
Bank Account Details sample

Quick-Start

require 'mindee'

# Init a new client
mindee_client = Mindee::Client.new(api_key: 'my-api-key')

# Load a file from disk
input_source = mindee_client.source_from_path('/path/to/the/file.ext')

# Parse the file
result = mindee_client.parse(
  input_source,
  Mindee::Product::FR::BankAccountDetails::BankAccountDetailsV2
)

# Print a full summary of the parsed data in RST format
puts result.document

# Print the document-level parsed data
# puts result.document.inference.prediction

Output (RST):

Field Types

Standard Fields

These fields are generic and used in several products.

Basic Field

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

value (String, Float, Integer, Boolean): corresponds to the field value. Can be nil if no value was extracted.
confidence (Float, nil): the confidence score of the field prediction.
bounding_box (Mindee::Geometry::Quadrilateral, nil): contains exactly 4 relative vertices (points) coordinates of a right rectangle containing the field in the document.
polygon (Mindee::Geometry::Polygon, nil): contains the relative vertices coordinates (Point) of a polygon containing the field in the image.
page_id (Integer, nil): the ID of the page, always nil when at document-level.
reconstructed (Boolean): indicates whether an object was reconstructed (not extracted as the API gave it).

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

String Field

The text field StringField only has one constraint: it's value is a String (or nil).

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:

bban_bank_code (String): The BBAN bank code outputted as a string.
bban_branch_code (String): The BBAN branch code outputted as a string.
bban_key (String): The BBAN key outputted as a string.
bban_number (String): The BBAN Account number outputted as a string.
