汽车安全与防盗最初的电子化开始于1994年的引擎防盗(IMMO)，恩智浦半 导体(当时的飞利浦半导体)作为第一家半导体公司把RFID的电子标签技术成功 的应用于汽车电子引擎锁：通过汽车与钥匙间的125kHz的无线通讯实现电子身 份识别，来判断启动汽车引擎。这一技术极大的提高了汽车的安全性，很快就在 欧洲以及北美地区广泛应用，并在短短几年时间内使欧洲的汽车失窃率大幅降低 了90 ，因而成为整个欧洲的汽车标准配置(Automotive safety and anti-theft electronic originally began in 1994, engine anti-theft (IMMO), NXP (then Philips Semiconductors) as the first semiconductor company to RFID electronic tag technology successfully used in automotive electronic engine lock: By car keys between 125kHz and wireless communications for electronic identification, to determine start the car engine. This technology greatly improves the car' s safety, soon in Europe and North America, widely used, and in a few years time so that European auto theft rate significantly reduced by 90 , and thus the entire European automotive Standard configuration)
