手机NFC车钥匙来了，比亚迪将与华为智卡联手推出
日前，比亚迪宣布比亚迪DiLink和华为智卡HUAWEI AI PASS联手，将推出手机NFC车钥匙功能，产品正式上线后，比亚迪车主将能够通过华为或荣耀手机解锁和启动车辆，即便在手机没电的时候，照样能解锁汽车。此项服务将利用手机的安全芯片和NFC来实现手机NFC车钥匙的操作，用户可以在比亚迪云服务App上关联华为钱包，激活车钥匙功能，并在汽车左前后视镜附近刷手机完成解锁、锁车的一系列动作。而且，NFC功能不受手机电量的限制，不需要通过手机App和蓝牙，即使在手机息屏、电量少、没电、甚至关机24小时内的状态下，也可实现解锁、上锁的操作。自此，比亚迪DiLink将提供实体钥匙、蓝牙钥匙及NFC钥匙三种车钥匙服务，满足用户在不同场景下的使用需求。
至于网络安全方面的考量，华为手机的NFC功能遵循全球车联网联盟CCC规范，将密钥和算法逻辑保存在手机芯片中，不会被任何第三方应用访问，无需担心被复制或暴力破解。关于手机NFC车钥匙支持的车型，目前官方暂未透露，我们也将持续关注。
