SBSDKHealthInsuranceCardRecognizer

@interface SBSDKHealthInsuranceCardRecognizer : NSObject

Recognizer for German-issued European health insurance cards (EHIC), a.k.a. elektronische Gesundheitskarten (eGK). The recognizer performs validation on the result that is specific to German cards and returns a failure result if any of the fields that can be validated fail validation. NOTE: In order to operate, this class requires tesseract languages and trained data to be present in the application bundle.
