Integration​

Take a look at our example apps to see how to integrate the Medical Certificate Scanner.

Adding the feature as a dependency​

MedicalCertificateScanner is included in Scanbot SDK package 4. Therefore, add the dependency io.scanbot:sdk-package-4 or higher in your build.gradle:

implementation("io.scanbot:sdk-package-4:$latestSdkVersion")
implementation("io.scanbot:sdk-mc-assets:$latestSdkVersion")
implementation("io.scanbot:sdk-common-ocr-assets:$latestSdkVersion") // <<-- please also add this dependency
implementation("io.scanbot:io.scanbot:sdk-package-ui:$latestSdkVersion")

Some medical certificates contain additional information in the barcode. For such cases, you also have to add the dependency with the Barcode Scanner assets:

implementation("io.scanbot:sdk-barcode-assets:$latestSdkVersion")
caution

Do not use multiple scanners (e.g., MRZ Scanner and Credit Card Scanner) at the same time.

Each scanner instance requires a lot of memory, GPU, and processor resources. Using multiple scanners will lead to performance issues for the entire application.

Initializing the SDK​

The Medical Certificate Scanner is based on the OCR feature of the Scanbot SDK. Please check the OCR documentation for more details.

In order to use the Medical Certificate Scanner you, need to prepare the English OCR language file.

Place the eng.traineddata file in the assets sub-folder assets/ocr_blobs/ of your app.

Then on initialization of the SDK, call the prepareOCRLanguagesBlobs(true) method:

Initialize SDK
loading...
caution

Unfortunately, we have noticed that all devices using a Cortex A53 processor DO NOT SUPPORT GPU acceleration. If you encounter any problems, please disable GPU acceleration for these devices.

ScanbotSDKInitializer()
        .allowGpuAcceleration(false)
