Smartphone Telematics: Choosing the right sensor to collect your telematics data
The sensor you pick shapes your program’s data quality, user experience, cost profile, and compliance. A well-matched sensor delivers driving behavior insights, minimizes fraud risk, and streamlines back-office integration.
Key evaluation criterias to consider for your mobile telematics data sensor
- Accuracy: Trip detection, policyholder driving behavior data, and precision of mileage driven
- Installation & Adoption: Professional fitting versus self-install options versus no installation required
- Cost & Business Model: Hardware, connectivity (cellular or Bluetooth), and maintenance expenses
- Compatibility & Coverage: Supported vehicles and geographic regions
- Security & Fraud Prevention: Tamper detection and reliable vehicle identification
Let’s take a closer look at OBD devices. Exploring the benefits they offer, and the challenges they present for telematics data collection.
Benefits of the OBD device telematics sensor for your connected insurance program
While smartphone-only UBI programs score convenience points, OBD-based telematics remain dominant, especially in commercial fleets since they:
- Secure, Dedicated Link
OBD plugs encrypt data between the car and insurer’s server, eliminating reliance on smartphone networks. - Instant Vehicle Identification
The OBD port verifies each vehicle at ignition, ensuring you always know which car generated the data. - High-Precision Telematics Data
You’ll record mileage and trip details with exceptional accuracy. This is critical for usage-based insurance solutions focusing on distance driven (PAYD: pay-as-you-drive). - Value-Added Services
Integration with vehicle systems unlocks diagnostics, maintenance reminders, crash notifications, and roadside assistance.
Ideal Use Cases for OBD Telematics:
- Mileage-based insurance programs
- Commercial fleets and connected-car services
- Mature drivers or senior policyholders
- High-fraud-risk or multi-user vehicles needing hard-wired security
- Vehicle-centric performance evaluation
OBD Device Advantages vs. Challenges: A Comparative Table
The table below shows the advantages and challenges associated with OBD telematics solutions:
OBD Device Advantages |
OBD Device Challenges
|
| Uniformity. Using this device ensures that the data collected will be fair and unbiased across all demographics, vehicle types, vehicle uses, and drivers. |
Limited to a single port. Each vehicle only contains a single OBD port supporting one device at a time. |
| High reliability providing accurate vehicle identification and trip detection. Solutions based on OBD hardware are highly reliable, using proven methods to establish the necessary vehicle-to-insurance carrier connectivity. Data is transmitted to the insurer quickly and accurately. |
Higher hardware costs. Cellular-based OBD solutions have a higher operational cost for the hardware plus cellular service. Costs can be reduced by adopting OBD with Bluetooth, but the expense still remains higher than using the smartphone as the only trip-capturing sensor. Hardware costs are diminishing as design improvements are made, but still represent a potential obstacle for insurers seeking telematics at the lowest cost. |
| Value-added services. Integration with internal vehicle information opens opportunities to provide value-added services, such as maintenance reminders, roadside assistance, crash notification, car diagnostics, and more. |
Vehicle compatibility concerns. OBD availability is limited to light-duty vehicles manufactured later than 1995 in North America, and in the 2000’s in Europe. Mostly outside of North America, there are still a few vehicle models that don’t come with an OBD port. |
| Exceptional security. The nature of an OBD hardware-based solution minimizes possibilities for fraudulent acts. Many solutions immediately detect the deliberate removal of the OBD device. |
Policyholder installation and adoption. Policyholders may become hesitant to install hardware within their vehicle due to a lack of familiarity with different technology compared to consumer-accepted smartphone practices. |
| High trip data accuracy. This solution delivers exceptional mileage accuracy for programs that require tracking telematics data. |
Requires driver ID for multi-driver applications. A driver ID mechanism is required in scenarios where vehicles are shared, a to accurately implement the insurance program |
