comment Proof of SIM card possession on iOS devices
A SIM card is not just a dumb memory storage, it's actually a smartcard with a CPU, RAM, ROM, and tamperproof storage area, and has an embedded OS and is capable of running applications written in a subset of Java.

comment How should passwords be stored if they must be recoverable?
The security of such system is basically the weakest link. You might as well not bother with saving it in non-recoverable format and simplify your system with just the PKI-encrypted password.

comment How to secure a public device against abuse?
Banks manage to put camera in ATMs. Also, maintenance isn't an issue, the charging station needs maintenance even with no camera anyway.

If they're really concerned about damages, they should have just added a camera to the station. That'll protect the user and the station, and cuts down the complexity of having to have a separate app to charge a car.

comment Is it legal to “use” security vulnerabilities
It might seem ridiculous that you can be sued for doing the right thing, but that's just the way things are in certain jurisdictions

If you're really concerned about it, you may be able to report the security vulnerability anonymously. Just make sure to take some precautions that make it not easy for them to track it back to you. Make sure the tone of the report couldn't be misinterpreted as a threat or blackmail.
