Firstly, I believe the QI scheme includes a process for communication, mostly restricted to "how much power should I send" for now, but it's obvious this will be expanded to more functionality as people basically replicate NFC over it.
Second, I'm still waiting to see a QI charger than just pumps 100W of power straight through any piece of metal above it. Don't know what would happen, but I naively imagine forced induction would brick most devices.

- im3w1l 3y agoHard disagree. If physical proximity was all it took to compromise a phone everyone would immediately protest. USB requires an active action. Blaming the user is still wrong, it really should be safe to charge in a mall or get a file from your friends usb stick. But it's less obvious so here we are.
- amluto 3y agoAs I understand it, Qi has a digital communication channel from the phone to the charger but no digital communication from charger to phone. So any exploit over Qi would have to somehow compromise the phone’s charging system with just analog field variations (frequency, field strength, or whatever else the phone measures).
