Please follow the steps below to license Dynamsoft Barcode Reader:

1. Get license key(s)

   For paid customers, you should get an email with the full license and the download link of the full version installer. If not, please contact sales[at]dynamsoft.com.

   For trial users, you can get the trial licenses at the installation directory or MyTrialLicenses site.

   • For Windows Edition, the licenses can be found at /{INSTALLATION FOLDER}/LicenseManager.exe.
   • For JavaScript Edition, the license key can be found in the /{INSTALLATION FOLDER}/DBRResources\dynamsoft.barcodereader.config.js.
   • For Mac Edition, the licenses can be found at /{INSTALLATION FOLDER}/BarcodeReaderTrialLic.txt.
   • For Linux and Mobile Edition, please contact us at support[at]dynamsoft.com for license extension.
   NOTE: If the trial license expires or the license is missing, you can still get the barcode reading results but some part of the content will be replaced with "***".

   Dim reader As BarcodeReader = New Dynamsoft.Barcode.BarcodeReader()
   reader.LicenseKeys = "88FFAA0******;9C42D5D******"

   PHP:

   $br->initLicense("88FFAA0******;9C42D5D******");

   iOS SDK:

   br = [[BarcodeReader alloc] initWithLicense:@"0C85972******"];

   Android SDK:

   BarcodeReader mBarcodeReader;
   mBarcodeReader = new BarcodeReader("B8C43F6******");

   JavaScript SDK:

   // In the dynamsoft.barcodereader.js file
