For more than 20 years, WINOWIG has worked together with local communities and regulatory authorities. The proven app technology from WINOWIG and the efficient handling of ETI park guarantee above-average success.

3 Steps to Success

  1. Parking Signs: ETI park provides legally compliant text.
  2. App: Available for free. Easy installation and handling on every smartphone.
  3. Parking Ticket: Friendly ticket notifying the driver about his parking offense.

Parking space providers or managers only have to stick the ticket to the vehicle's windshield. Adress research, invoice and dunning is professionally handled by ETI park.


For operators of public transport, ETI experts provides a professional solution to credit outstanding receivables from unpaid annual subscriptions or other infringements. In traffic, offenses against the road traffic regulations are among the most frequent reasons for issuing tickets and fines. A holiday or a business trip to a neighboring European country may also result in fines due to unpaid toll charges or speeding.

ETI experts work in close cooperation with local authorities and police. As a collection service provider, we can collect from debtors on claims governed by public law within the framework of cross-border EU regulations.
