20 Brand New Tyvek® RFID Secure Credit or ID Card Protector Sleeves

My Chase credit card recently expired and when I received a new one, I noticed that it had an RFID (radio frequency identification) chip embedded in it (your card sends out a signal and can be read by putting it near a reader instead of swiping it). I did not feel safe with this information being transmitted and found these Tyvek RFID security sleeves that limit the transmission of this data. These sleeves are made of Tyvek (which is an extremely durable, tear resistant and water resistant fiber) on the outside and has a special inner lining which blocks the transmission of the RFID signal.
