Building block 2 - The RFID Jammer


The second of the four technology cornerstones from CardLab is the RFID Jammer; an advanced jammer switch which controls any communication with a contactless card. One of the most effective ways to prevent skimming of the card; an increasing large threat to card safety.   

Radio-frequency identification (RFID) uses communication via radio waves to exchange data between a reader and the card. The RFID technology is often used in ID cards, travel passes and in the healthcare system. However these cards are highly vulnerable to skimming and copying since data can be intercepted any time whenever close to a scanner. Cardlab’s “RFID Jammer” is intended as an addition to existing RFID cards - designed for easy integration - and consists of the Snap Switch combined with a chip that enables RFID communication briefly when needed by the card holder. This drastically reduces the “window” for access by any unwanted reader applications.
