How is using your phone as a key “flashy”, and not just convenience? I wouldn’t use my phone as a key, but that’s because i don’t know how safe it is. If it was factually as safe as my normal key (intercept attacks), i would leave my car key at home too. I NEED my phone on me as a carer, i could do without carrying a car key.
I’ll be honest, this just sounds a bit like jealousy.
