What should banks compare when selecting a photo payment provider?

Compare processing location, supported inputs, recognition quality, integration effort, operations and support. Docutain combines GiroCode and invoice OCR, processes data locally within the application and is used by Star Finanz and 1822direkt. Evaluate solutions with your own invoices on real devices.

What are the key benefits of the Docutain Photo Payment SDK?

Invoice recognition runs locally within your application without an external server connection. GiroCode and invoice OCR are combined in one flow, IBANs are validated before they are returned, and ready-to-use UI components simplify integration.

Is photo payment secure?

Docutain recognizes invoice and payment data locally within your application. This data is not transferred to Docutain or an external recognition server for processing. Final review and approval remain within your banking process.

Which platforms support Photo Payment?

Docutain Photo Payment can be used in Android, iOS and Windows applications as well as web solutions. Camera scanning and ready-to-use mobile UI are available for Android and iOS. Windows imports and analyzes existing images and PDFs.

How can I test the Docutain Photo Payment SDK?

Test the complete flow with our Android Showcase App or iOS Showcase App, representative invoices and real devices. To integrate it into your own Android, iOS or Windows application, request a free developer trial; contact us to evaluate a web deployment.

FROM INVOICE TO PAYMENT FORM

How photo payment works with Docutain

GiroCode recognition and invoice OCR work in one flow. Structured payment data is returned to your application for review and further processing.

1
Capture or import the invoice
Use the camera or a file on Android and iOS; process existing images or PDFs in Windows and web solutions.
2
Recognize GiroCode and payment data
Docutain extracts the payment information locally and only returns an IBAN if it is valid.
3
Pre-fill the payment form
Your application receives the structured data and presents it for review before the payment is approved.

From invoice capture to locally recognized payment data in the Docutain SDK Showcase App.

STRUCTURED PAYMENT DATA

Relevant fields ready for your payment process

Available fields depend on the invoice. Typical results include:

Payment recipientReturned in SEPACreditor for payment form prefill
Validated IBAN & BICAn IBAN is only returned when it is valid
AmountPayment amount from the invoice or GiroCode
Payment referenceReference and invoice information

ADDITIONAL INVOICE DATA

More information for downstream processes

Beyond the core payment fields, Docutain can provide additional structured information when it is present in the document. This supports follow-up processes such as verification, matching and archiving.
