Would you like to find out for yourself how C-Compact can be used for pool vehicle optimization? We are happy to introduce you to the features of our fleet management system in detail.

Fleet management with C-Compact – Fleet management system with sophisticated access control

Maintain automated access control and increase vehicle utilization

C-Compact's integrated access control only gives authorized and identified persons access to your (pool) vehicles. When using the system with reservations, these are transmitted to the vehicle and assigned once and unambiguously in this way.

The use of the wrong vehicle or at the wrong time, as well as double bookings are no longer possible and prevent operational follow-up problems and costs. Existing reservation/fleet management systems can be used to manage time dependent bookings. Alternatively, your own booking or fleet management tool can be connected to our server. Thanks to the uncomplicated and flexible vehicle allocation, our pool vehicle optimization system can significantly increase the utilization of your fleet and significantly reduce operating and acquisition costs.

Access via App or RFID-cards

  • ​​​​​​Convadis smartphone app: The app enables vehicle access via the Bluetooth function of the smartphone. Since encrypted bookings or access tokens (digital keys) can be forwarded to the vehicle via smartphone, access via app also works in underground car parks without mobile phone reception.

    The Convadis app is freely available on the Apple Store (iPhone) and in Google Play (Android). If desired, the app can also be adapted to the CD/CI of your company (white labeling) or fully integrated into your company app as a fleet management system (see “CAppLib”). Personalization of the app is conveniently done via QR codes or deep links.

  • RFID cards: Access to the vehicles in your fleet is possible via RFID cards or badges. Existing badges/cards e.g., for building access, time tracking, beverage vending machines, etc. can also be used. This means that no additional cards need to be purchased and managed.

    Our fleet management system can easily be used mixed with app and RFID cards. 

Time-independent access via "white-list"

Depending on the application, unrestricted access to the vehicles is often sufficient – i.e., without prior reservation for a certain period of time. In this way, for example, the handover of keys between different drivers can be simplified, for example in large areas or when drivers are frequently changing. In contrast to a fleet system based on bookings, the IDs of up to 1200 users are stored as a “whitelist” in the memory of our devices and conveniently managed via CCom. Access can therefore be granted without instant cell phone communication.

As a result, no connection to a booking system is required for this type of use, which significantly reduces system costs. Of course, vehicle and usage information are also available with this solution via our CCom web interface or the interfaces to third-party systems. Thus, our fleet management system provides a complete overview of the respective drivers and their use at all times.

Reservations and permanent access control can be used in a mixed way without any problems. When used with time-dependent bookings, “whitelist” access is often used, for example, to give employees or technicians permanent access to the vehicles. With C-Compact, you get a strong and very flexible fleet management system.

No need to hand over the keys

The vehicle key is placed in the glove compartment as standard, so the handover is completely omitted. Unsafe handover locations, high effort and long waiting times for handover, as well as missing vehicle keys are a thing of the past with our fleet management system. However, many vehicle models are also used completely keyless in combination with our system.

Fleet Management System – detailed information on location and usage

With C-Compact you have full control and overview of your entire fleet – regardless of the respective location. Our system for pool vehicle optimization can easily be used for a large number of vehicles regardless of location and allows not only the location determination but also an exact recording of all trips and vehicle data.

  • Multiple users/separation of trips: Multiple users can access the vehicles by using RFID cards and/or the app. Reservations can include several (max. 13) authorized users. Every user change, even within a reservation/usage, automatically generates a partial trip data record in our fleet management system, which contains all relevant data for the logbook or billing. For example, business and private trips can be separated by storing a private and a business ID for each user.
  • Location determination: C-Compact is also optimized for fleet operation with many different locations. These do not have to be fixed: one-way trips are also possible. The exact position of the vehicle is known at all times thanks to GPS determination, which means that you always have a clear overview.

Pool vehicle optimization - fleet optimization based on collected data

In addition to enhanced security and a high-level of operating comfort, the collection, transmission, and evaluation of trip and vehicle data are among the core elements of a strong fleet management system and thus create the basis for fleet optimization. The data helps you to optimize your fleet size – with exact usage data, unused reservation times, unused bookings, and repeated long periods without usage can be detected and tracked.

This detailed tracking is actively enabled and supported by our intelligently designed fleet management system: Each access, whether based on reservations or via permanent access generates one or more driving data records, containing all relevant (partial) usage data for analysis for internal billing and, if necessary, the designation or charging of private trips. This provides you with a strong database for the long-term planning and optimization of your fleet.


If required, the fleet management system provides all data for a recognized logbook. It completely eliminates the need to keep a logbook manually, missing or incomplete entries, and the associated administrative effort can simply be avoided. Depending on the configuration, it is also possible to provide the necessary data for partial journeys, e.g., to record every logout of the user or ignition on/ off event or send part trip data after some time without vehicle movement.

Instead of access control based on bookings or whitelists, the device can be configured in a way that the user must re-identify certain time after ignition was switched off. Thus, our fleet management system provides full support for a very detailed logbook that can be easily used for internal and tax purposes. In logbook mode, the effort required to install the device is reduced to a few minutes, as the device only has to be plugged in and attached to the windscreen.

Diagnostics and vehicle status

The available diagnostic and vehicle information enables the timely initiation of repairs and prevents corresponding vehicle failures. If desired, information about driving behavior can also be recorded, e.g., for CO2 reduction measures or for Corporate Social Responsibility projects.

C-Compact gives you the ability to configure all the details of data collection according to your needs to perfect fleet optimization and reduce TCO. Below you will find a selection of the available information:

Start time of trip

End time of trip

Driven distance

Total mileage at the start and end of the journey

Information about removal and return of fuel/charging/parking cards

Fuel level at the end of the journey or in the case of electric vehicles battery level and status of the charging plug

GPS coordinates/tracking information

The GEO coordinates of the vehicles can be requested at any time or, depending on the configuration, transmitted to the server periodically or on event (e.g., at every ignition on/off or login/out event). This function can be restricted or completely switched off, for example for data protection reasons


Information about ignition (on/off), doors (open/closed/locked), windows (open/closed)

Fuel or charge levels for electric and hybrid vehicles

Battery voltage, alarm if battery level is too low

Diagnostic information / diagnostic trouble codes (DTC) recorded by the vehicle

Information about harsh breaking, rapid acceleration, harsh cornering

Damage detection


Fuel consumption

Vehicle Speed / engine speed / Direction of travel

Operating Hours

Idling time (engine runs without movement)

Excessive acceleration and harsh braking

Detection and alerting in the event of unauthorized vehicle movements



The “Always on” technology implemented in our fleet management system guarantees the prompt transmission of data to the head office. As a fleet owner, you are always informed about all the details about your vehicles and can take short-term measures, as well as plan a long-term optimization of your pool vehicles.

Cost-effective data transmission

Due to our specially compressed and data-saving transmission method, the communication costs remain extremely low. We are therefore also offering a very cheap SIM card including data volume starting from € 0.50 per month and vehicle. Of course, you can also use our fleet management system with your own SIM cards.


All data transmissions to and from the vehicle are pseudonymized and encrypted. The access to the CCom web interface is finely scalable by roles and domains. The transmission of position data can be completely switched off or adapted to your needs. This means that you can easily meet all the requirements of the EU data protection directives (GDPR).

Our fleet management system –That’s what C-Compact is all about

Only about 0.5 to 1 hour is usually needed to install C-Compact in a vehicle. The device is supplied with a suitable connection cable, on request also with OBD plug, and preferably attached to the windscreen of the vehicle.

Everything integrated in one device unit

In addition to the actual electronics, our C-Compact main unit also contains all antennas for GPS, cell phone, and Bluetooth communication.
