This document provides specifications for a fingerprint car security system with mobile alerts. The system can store up to 9 fingerprints, lock/unlock the car with a keychain remote, cut fuel to the engine if triggered, and send status alerts via SMS. It uses a 315MHz radio frequency for the remote, rolling code encryption, and has inputs for a 12V car battery with a working temperature range of -15 to 65 degrees Celsius. A professional installation is recommended to properly set up the fingerprint reader module, system controller box, and SIM card functionality for SMS communication.
