How To Disable Rfid Tags

Date:Aug 11, 2020

As more and more products and devices with built-in tags are created, the potential for abuse of this technology only grows. 


What you do with your credit card: Melt the chip's antenna and unscrew the magnetic strip on the back so that it becomes unwipeable. If you kill the RFID chip in this way, there is enough space to never be able to read it again. What to do with a passport: Make it as easy as possible to kill the RFID tag on your passport.


The problem with this method is that it is not permanent and you can probably reactivate it without your knowledge. One that can be offered by industry is an RFID deactivator that sends the RFID tag to sleep but is only turned on for a short time. If you cut the antenna off from the microchip and fry it in an ordinary microwave oven (which you need), you know you have permanently disabled it. 

Basically, the microwave oven method copies the RFID deactivation method, but on a much smaller scale, and copies it to a different type of RFID tag


The reader converts the radio waves of the RFID device into a form that can then be used by a computer. Chip and antenna are called "RFID" devices or RFID tags together with the carrier substrate. One of the most important aspects of identifying an object using RFID is the storage of serial numbers and other information that identifies the object on the microchip attached to the antenna. 

With a modified antenna structure, it can be converted into one that has a range of about a few centimetres. The ability of the base station reader to query the RFID tag transponder wirelessly has been greatly reduced, but not eliminated. Although some antenna structures are still in place, RFID tags can still be read with the help of a computer. 


In addition, some data protection countermeasures, such as the use of an RFID chip, can be abused to achieve the same effect. This changes the tag in a similar way to the FIGS. 


A trivial example of removing labels is when a thief in a supermarket exchanges the RFID tag of an expensive product for a cheaper one and pays less at the checkout. An RFID tag that is not embedded in an article can be removed from the article and attached to another to change the price tag. 


The identification of articles with RFID tags allows users to identify and track inventory values automatically and uniquely. RFIDs adopt auto-ID technology by allowing the tag to be read from the line of sight. Depending on the type of RFID, you have access to a unique identifier (ID) for each element in your inventory as well as the location of the element. If the RF-ID system cannot correctly associate a tag ID with an object, the integrity of the data in the back-end system is compromised and the object can easily be found. 


RFID was used in aircraft to identify friends and enemies during World War II and in the military during the Cold War. 


The technology has continued to improve year after year and the costs of introducing and using RFID systems continue to fall, making them more cost-effective, effective and efficient. The need for a base station reader to wirelessly query RFID tags and transponders has thus been greatly reduced, but not eliminated. While some antenna structure is still in place, RF-ID tags can be read out in the same way as a traditional radio signal. 


With a modified antenna structure, you can be transformed into one with a range of about a few centimetres. The tag is changed similar to FIGS. 343, filed by 11-482, for the purpose of which all references contained herein are incorporated in their entirety into this content. 

The present invention concerns a technique which enables a device to advertise its functioning by means of an RFID tag attached to the device. It is known that RFID chips are only readable from a distance of a few centimetres when coupled to an antenna. If the antenna is properly mounted, it is not too much visible from the outside. 


RFID tags are attached to objects to be tracked with an RFID reader and an antenna. They transmit the data about the object via radio waves to the antenna - reader combination via the radio wave. It consists of a transmitter and receiver (antenna) for sending and receiving signals and the RFID chip (integrated circuit or IC) that stores the tag ID and other information, as well as the reader (or reader) connected to it. 


RFID tags do not have a battery as specified by Active BAP tags but receive energy from the radio waves generated by the reader.
