Transportation fares

Being and staying mobile is very important – whether by car, bus, or train. As an operator of public transport such as buses and trains, you offer your customers a high-quality service. You in turn rely on the payment of transportation fares. Specialised in the transport sector, ETI experts ensures that you can credit outstanding receivables from unpaid annual subscriptions or other infringements.

Private parking surveillance

Parking offences on private parking lots are increasing. Do you provide parking spaces in business parks, shopping centres, supermarkets, hospitals, or residential buildings? We support you in claiming default charges from parking offenders. Your private parking surveillance pays off.

ETI experts has successfully specialised in the field of parking space monitoring in the traffic and mobility industry. Record the parking offender quickly and easily with the ETI park App – we take care of everything else.

ETI park APP – in cooperation with WINOWIG.

In 3 steps to success

Parking Signs

Your rules apply to your parking areas. Violations of proper parking will result in a penalty for breach of contract or damages for breach of title. We provide a legally compliant text for your signs for free.


Capture unauthorized parking vehicles easily via app on your smartphone. The app is available for free from us. The car data will forward you to us. Our employees take care of everything else: the identification of the car owner at the Federal Motor Transport Authority, the necessary communication with regard to questions and objections, the monitoring of the payment period and the booking of incoming payments.

Parking Ticket

Stick the "nodule" in the form of a notification card to the windshield of the vehicle. She is friendly formulated and notifies the car driver about his breach of contract. You will receive free notification cards from us in the event of an ownership offense as well as for a contractual penalty.
