Latest Patents

Yanqing Du holds a patent for a "Shield for radio frequency ID tag or contactless smart card." This invention addresses the effective shielding of inductively coupled RFID systems. It reveals that a shield does not need to cover all sides of the device completely. The design allows for a shield of any shape that facilitates current flow in a closed loop. The primary requirement is that the back electromagnetic field (EMF) from the shield induces sufficient flux to cancel the magnetic flux from the reader. Notably, the shield can function even with a small induced flux, as it can shift the self-inductance of the RFID or contactless card coil. This shift can alter the resonant frequency of the circuit, impacting the power delivered to the chip. The invention allows for optical and mechanical access to the smartcard or RFID tag, leading to significant cost savings by using less shielding material.
