BlinkBarcode (PDF417.mobi) licenses are based on the number of users and one license is valid for only one app. The license is tied to the app Package Name (Android) and Bundle ID (iOS).
B2C, B2B or Perpetual license
If your app is available on Google Play/App store, then B2C licenses apply. If your app will not be available on Google Play/App store and/or if it will be used for internal users, in an enterprise, B2B environment or banking industry, then B2B licenses apply. B2B licenses are perpetual on annual basis. For inquiries about licenses please contact us.
If you are developing a library that would include PDF417 SDK inside, then you would need an embedded license. For inquiries please contact us.
The end-user count is done by the number of installs.
If you have a license for a certain number of users and your install base exceeds that number, then you should upgrade to the next license level. In that case, you will only pay the price difference from the previous license. To achieve this please contact us.
