Available from the Online Spy Shop, this magnetic car tracker is a credit-card sized gadget which is able to send the real-time location of a vehicle to a mobile phone.
Through either coordinates or a digital map, you can keep an eye on either where your spouse is heading to, or check on employees using company cars. Once you sent a text message to a particular number, the device immediately sends you location data.
A computer is not needed for this gadget to work, and the inbuilt battery will last one week. The car tracker uses a SiRF Star III chipset and a quad-band GSM modem.
Each tracker costs £234 ($375).
