MJCS has a capability to open biometric chips for documents that have it

Once backend asks for NFC, you should create the scanner and present it on the screen. Since NFC component requires backend integration, you need to pass some information from the previous response as well.

Swift

let nfcScanner = IDSNFCScannerViewController(credentials: IDSEnterpriseCredentials, lastStepResponse: IDSEnterpriseResponse, completion: @escaping CompletionHandler)  

The completion handler will return the outcome of the step. It could either return failure (please refer to interface documentation) or success with the next required action that the backend asked to perform if there’s any.
