RFID interference with CapSense

Last Updated: June 17, 2009

Question: Does RFID technology cause interference with your sensor technology? If so what is the effect range?

Response: When resistors are placed in series with all sensor inputs, CapSense is immune to RF interference up to 60V/m electric field. Since there are many RFID systems and standards, it is difficult to make any general statements about effect range. It can be said that through the simple technique of adding series resistors, CapSense is made compatible with many RFID schemes. There is a CapSense enabled game on the market that employs RFID tags in the game pieces.
