The service runs in the cloud and in the browser, and all you need to access it is an account. You can then start uploading fines and supporting documents.
The other (legal) requirements are determined by the type of fine and the jurisdiction of the fine you wish to process. The most important data are the name and address details of the end-customer/rentee/lessee, but in some jurisdictions you also need a date of birth, for example. These requirements can be discussed in detail during the demo or any further introductions.
