Document bundle
Processing of multiple different documents.
Verification of a bundle of documents is one of the most common use cases in document processing. Companies receive large amounts of documents every day. These documents require not only to be verified, but also to be identified before undergoing a precise processing workflow.
Introduction
Datakeen's OCR service automatically recognizes the document type to select the correct endpoint. It is then able to authenticate the document and extract information from each page. The platform handles images (JPG, PNG) and PDFs of these document types:
- ID card
- Passport
- Residence permit
- Tax statement
- Proof of address
- Payslip
- Driver's licence
- Bank account details.
Setting up the API
The synchronous API model can be used to operate on multiple documents at the same time.
API token is required
In order to perform any call, you will need an API token that can be retrieved thanks your API credentials. To learn about authentification, please refer to this page
