How to set trial license

To use a trial license, you can follow the steps below:

Get a trial license key.

You can log in the customer portal and request for a trial extension online.

Note: If the trial license expires or it is missing, you can still get barcode reading results but partial of the result will be masked with “*”.

Update the license key in source code.

You can use initLicense() or ProductKeys to set the license.
