Recently, Griaule released a new way of licensing, which will make much easier the license process for those who use the fingerprint sdk.
Now, when the customer buys the license, the customer receives a "product key", and the number of licenses he bought are credited in his account. The "product key" is a unique key associated with a user account, with this product key, the user can have access to all the licenses in his account. Also, now we have the "hardware key", which is an unique key associated with each computer in the world.
Combining the "hardware key" , the "product key" and the new griaule's license server, we have a robust way of licensing.
In order to use this new way of licensing , there are two main scenarios that are worth mentioning:
The application access griaule's server once
This is the easiest way. You just need to call the installLicense method at the beginning of the application.
Suppose your product key is AAAAA-AAAAA-BBBBB-KKKKK , then before initializing the sdk, you call
installLicense("AAAAA-AAAAA-BBBBB-KKKKK"); .
Notice , that this code needs to be executed at least once (if it executes more than one time, no problem ). When this coded is executed the first time, it connects to griaule's server, checks if the user still has licenses available, if the user has, it decreases the number of available licenses by one, and finally generates and installs on the computer it is being executed a license associated with the computer's hardware key.
Using griaule's license manager
If you want to manage your licenses, or if the machines that you want to install the licenses don't have internet access , you can use griaule's license manager. You just need to collect the hardware keys of your machines with the license manager, then you go to your account in griaule's website , download the license , and install in your machines.
