Latest Patents

McGoran holds a patent for a "Shield for radio frequency ID tag or contactless smart card." This invention addresses the effectiveness of shielding 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 a current to 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 while leading to significant cost savings due to reduced shielding material usage.
