Document Reader SDK 9.3 — March 26, 2026

IMPORTANT changes

Introduced the Server-Side Reprocessing of the Client-Side gathered mDL data. Now, captured mDL sessions can be securely transferred to the backend server and then reprocessed in a safe trusted environment to obtain final verification results.

Prior notice: Support for Ubuntu 20.04 will be discontinued in the upcoming major release. We will provide additional notice before this change takes effect and the new minimum supported version.

    • Argentina ID Card
    • Eritrea ID Card
    • India Visa
    • Lao People's Democratic Republic ID Card

Barcode

    • Argentina ID Card
    • Democratic Republic of the Congo Voter Card
    • Lao People's Democratic Republic ID Card

  • Updated parsers:

    • Belarus Residence Permit
    • Colombia DL
    • India Haryana DL
    • QR codes generated by a Spanish government application — MiDNI

  • Improved 1D barcode detection.

Text data parsing and validation

  • Added the name prefix in a separate text field.
  • Extended logic for SPECIMEN detection.
  • Updated parsing of DG11/DG12 field values into correct field types and LCID for documents from multiple countries.

Authenticity

  • Updated the neural network (NN) for electronic device replay checks with greater accuracy.
  • Updated the neural network (NN) for the document liveness check with greater accuracy.
  • Improved detection of digitally manipulated images.
  • Fixed an issue with the missing Barcode background check as part of the Liveness checks.

Enums

  • Added new eVisualFieldType enum members:
    • ft_Expiry_Timestamp
    • ft_Data_DateOfExpiry
  • Added new eRPRM_DeviceTypes enum member:
    • RPRM_DeviceType_FX_77x4M

Other

  • Introduced the Server-Side reprocessing of the Client-Side gathered mDL data. Now, captured mDL sessions can be securely transferred to the backend server and then reprocessed to obtain final verification results using local trusted PKD, similar to electronic identity documents through signature verification with public keys.
  • Added the ability to configure the impact of the expiry date on MRZ verification and Text field status calculations. By default, this setting remains enabled—if the document has expired, the MRZ and Text statuses are set to Failed. To disable this behavior, set processParam.strictExpiryDate to false. In this case, MRZ and Text statuses are set to OK, while only the Expiry status is set to Fail.
  • Added the capability to process individual RFID data groups from an ePassport/eDL/eID, parse them and perform the corresponding checks. If EF.SOD is present, Passive Authentication (PA) is also performed.
  • Added support for the processing results in XML in accordance with the BSI TR-03135 v2.5 standard.
  • Fixed an issue where portrait comparison results were missing when a damaged image was included in the request.
  • Code quality has been improved with minor issues fixed.
  • Updated internal dependencies to improve stability, security, and maintainability.

Core RFID SDK

  • Added support for ISO/IEC 39794-4 Amendment 1 2023-08, that defines how fingerprint images and related metadata are structured and encoded for interoperability between biometric systems. — As a result, ntfLDS_Biometrics_BDB_Version_Incorrect is no longer generated.
  • Added support for DSA-SHA224 and DSA-SHA256 digital signature algorithms.
  • Added new notification codes for TCC service errors.
  • The "Profiler type" setting has been deprecated. Regardless of the selected value, it now always defaults to sptDoc9303_LDS_PKI_Maintenance.
  • Fixed an issue where the PA status was returned as successful when DTC data group validation failed.
  • Fixed an issue with incorrect certificate selection from an internal PKD storage during chain building by considering matching country codes in issuer and subject.
  • Code quality has been improved with minor issues fixed.

Enums

  • Added new eRFID_NotificationCodes enum members:
    • RFID_Notification_TCC_TA_Resources
    • RFID_Notification_TCC_TA_Signature

Desktop API

  • Fixed an issue where incorrect information about the device in use was returned when multiple devices were connected to the same application.
  • Fixed an issue where the database was not updated on Windows when a newer version was available in the “Updates” directory.
  • Memory usage optimization.

Hardware Support

  • Fixed a connection issue with Desko devices after reconnection.

Mobile API

  • Added support for the Mobile Driver’s License Server-Side reprocessing.
  • Added the ability to select the PACE and CA types from options manifested in EF.CardAccess and EF.DG14 during the RFID chip processing.
  • Added the processParam.checkVDS option to perform the Visible Digital Seal (VDS) verification.
  • Added a new mechanism for image customization.
  • Added an ability to customize multipage processing animations separately for each document type.
  • Fixed an issue with the Close button position in the right-to-left (RTL) interface.
  • Updated sample projects on GitHub to align with the latest changes.
  • Code quality has been improved with minor issues fixed.

Android

  • Reduced the closing time of the camera activity after the processing is finished.
  • Fixed an issue preventing the camera from starting.
  • Fixed an issue caused by incorrect exposure area handling for rotated documents.
  • Fixed an issue where processing failed to start when showScanner was followed by a call to startNewSession.
  • Fixed an exception that occurred when the camera was already closed.
  • Fixed an initialization issue caused by a subsequent number of calls to initialization followed by deinitialization.
  • Fixed an issue with the status message background color that appeared on certain devices in dark mode.

iOS

  • Added the ability to use any external Bluetooth device for RFID chip processing.
  • Fixed an issue with incorrect RFID animation caused by disabling the rfidScenario.autoSettings
  • Fixed an issue with the Online Processing feature used in combination with the Face SDK integration where added live and external portraits were not included in face match and search calls to Face API.
  • Fixed an issue where RFID chip processing failed to establish a connection after mDL processing.
  • Fixed an issue where the status message indicated that a document search was in progress before the transaction was created when the Complete Server-Side Verification is used.
