• other trying for over-the-air power

However, the post is not about going over this technology itself - if you want to explore, check the links provided at the end.

To the point

Several couple of years proved consistently that wireless technologies (WiFi, RFID, remote controls, GSM, etc.) are very prone to security vulnerabilities (sadly, most often by design, rather by implementation).

The types of attack one can envision are:

• wireless power theft
