Carsharing services enabling a pay-per-use access to individual vehicles are experiencing a growing pervasiveness as they can help users to enjoy a tailored experience that can optimize cost-of-ownership based on individual needs.

Companies providing this service need access to real-time information on each vehicle’s position and status as well as the ability to verify user’s rights in accessing the vehicle. Dedicated telematics systems are installed in each vehicle collect this wealth of information and make it available to the fleet manager.

ST’s wide product portfolio can help build complete on-board unit solutions for shared vehicles with a range of automotive-grade NFC transceiver ICs for smart car access, SPC5 32-bit Power Architecture microcontrollers with embedded an hardware security module (HSM), secure elements, GNSS devices and Bluetooth connectivity ICs and MEMS inertial anti-tamper sensors.
