+# Desktop Passport MRZ Scanner for Windows and Linux
+This C/C++ sample demonstrates how to implement **MRZ (Machine Readable Zone)** recognition using the Dynamsoft Capture Vision SDK.
+
+## Prerequisites
+- [CMake](https://cmake.org/download/)
+- [OpenCV 4.5.0](https://opencv.org/releases/)
+- [Dynamsoft Capture Vision Trial License](https://www.dynamsoft.com/customer/license/trialLicense/?product=dcv&package=cross-platform)
+
+
+## Getting Started
+1. Set the license key in `main.cxx`:
+
+    ```cpp
+    iRet = CLicenseManager::InitLicense("LICENSE-KEY", szErrorMsg, 256);
+    ```
+
+2. Build and run the application:
+
+    ```
+    mkdir build
+    cd build
+    cmake ..
+    cmake --build .
+    ```
