The answer will depend upon the timeframe in which it is used and the environment in which you are testing. - For ongoing development and testing, you can purchase a license from the online store to cover your usage. If you expect to consume a large volume of scans or browser clients during your dev or testing, please contact us for a discount. - For evaluation, you can use the 30-day free trial SDK provided by Dynamsoft. - For temporary development and testing, you can contact support@dynamsoft.com or log into the customer portal to get a 15-day (max. 30 days) temporary license.
