RFID-Zapper
`The RFID-Zapper is a gadget to deactivate (i.e. destroy) passive RFID-Tags permanently. The development-team presently consists of two people. Goals are a proof-of-concept and the construction of at least one functioning and appealing prototype, as well as a documentation of the project, so that everyone can build an own RFID-Zapper. [..]
The RFID-Zapper solves this dilemma. Basically it copies the microwave-oven-method, but in a much smaller scale. It generates a strong electromagnetic field with a coil, which should be placed as near to the target RFID-Tag as possible. The RFID-Tag then will receive a strong shock of energy comparable with an EMP and some part of it will blow, most likely the capacitator, thus deactivating the chip forever.’
