Indeed. I would think that a fair few of us have such security anyway as it is a requirement for Google/Apple Pay. What I found on my Digital Key expedition was this:Security and user experience has to be balanced.
I arrived at the Tesco car park and locked the car with the digital key.
Went into Tesco and because I have both data and wifi enabled, the phone switched from data to the free Tesco wifi.
When I left the store after a few minutes, it switched back to data. No real problem with this as it was what the phone should do.
I did find though that to unlock the car again, I had to go through the iSmart menus, re-input the 4 digit code and then wait for it to recognise through the server and unlock the car.
There is absolutely no real problem with this but it would have been quicker with the key fob.
There's no doubt it is a clever feature which would be useful in case of lost/misplaced keys.?
