One single key can have multiple transactions - e.g. each time the key was used for a new installation or a regular online check was done, a new transaction for this key is generated. The transaction list gives you a complete history of the key usage.

 

In the example below the transactions tell the following story:

 

•Ryan made a product activation on computer 8604.fritz.box and it was successful

•Alisa tried to use the same key on computer e5b5.fritz.box but the product activation failed because the key was already used

•The key ID / usage was changed because a few minutes later the product activation was successful

•The column Effective Key / ID usage indicates, that the key was used on 2 different computers

•The column Next date of license check indicates, when the next online check would be due. This is only relevant if the online check is enabled in the application
