I cant take my phone into my workplace at all (not even to be left at reception/entry) - I therefore have to leave it in the glovebox oy my car. What is the best way to manage this? I presume I can lock my car with a card and open it also - but will the phone in the car impact? Any suggestions - only thing I can think of is to turn off my phone (or Bluetooth) and leave it in the car, using the card to lock and reopen? Any smarter ideas? Thanks (p.s taking my phone with me onto our premise is not an option at all [security] - and I do have to lock my car on exit).
