Have you ever lost your car on a parking lot? You don’t have a clue where your car is after shopping. Then you start walking around clicking on your car keys so the alarm goes off. It can be annoying, especially on a hot sunny day.

No, you needn’t install(安装) an expensive GPS system to keep track of your car. That’s too expensive. You would need to pay a monthly fee to use it.

But is there a way to track your vehicle without spending a fortune? Yes, now there is! A California-based company has created a tiny device that works with your smartphone, which could be exactly what you’re looking for!
