content: The microwave did work for an RFID Sticker, but we have a RFID Chip that is ceramic coded. We need a solution for the Chip.

content: Put the RFID chip in the path of a tesla coil discharge may work (ESD to the max).Is this a chip imbedded in your body, by chance? And are you afraid of being tracked? If so, cut out the chip and leave it in a Uber car or a long haul truck or train.

content: Do you want to deactivate one RFID semiconductor or a tag (a chip plus antenna), or a bunch of RFID chips or tags?Why?Without knowing more about your objectives it might be worth noting that most RFID tags that operate in the 915 MHz range are passive, which means they have no battery and they can't transmit unless they are energized from a reader (interrogator), and generally that needs to be within 30 feet of the tag, and sometimes within 10 feet or so. So unless you have a reader nearby nothing on the tag is likely being read. Additionally, what is on most tags is an Electronic Product Code (EPC) which is vendor/product info and a serial number unique to the item it was attached to - so the value of the info on the chip is generally pretty low.Other RFID chips that operate in the Near Field (known as "NFC" for Near Field Communications) typically have a much shorter read range (a few inches or less), so again unless a reader is in pretty close proximity the info on the chip is likely difficult to access. Info on NFC chips might be of greater value than EPC tags but the NFC chips used for sensitive applications are likely to be encrypted.There are various RFID standards which are published specifications and some versions are designed to enable RFID info to be "killed"/disarmed once the tag (generally on a consumer item) moves past the manufacturing and distribution supply chain and beyond the retail point of sale into the consumer's possession.So, what do you have in mind?
