make a door lock …
make a door lock that changes its access code randomly every hour. when you’re outside you touch your phone to the door. the coil sends the current unlock code encrypted with? a shared secret between the arduino and your android phone. the phone receives and decrypts the code that you can then enter into a keypad. welcome home 🙂

It? can be used as QRCodes, to transfer URL information to the phone. May be with larger coils and more electromagnetic amplitude, you can just touch something with your phone and get info about it.

Yes:? one way from coil to phone unfortunately. It’s not very practical, but I can’t help thinking that there may be *some* practical application for this… I just can’t think of it 🙂

Got it, now I checked your blog. Brilliant idea !?
@Feliexxxxxxxx …
@Feliexxxxxxxx Ironically, the iPhone probably can do this. Instead of utilizing NFC dedicated tech, this solution utilizes the phone’s compass (magnetometer) to detect changes in electric fields – While the iPhone doesn’t have NFC capability, I don’t think it? would have trouble pulling off this kind of communication. Props to @jdesbonnet for the technique!
