The paper is both very thin and flexible—but it is also an amazing piece of technology. Sandwiched between the inner and outer layers of paper is the nano thin layer of metal—and it is precisely this metal layer which provides the barrier for RFID protection. This combination of paper and metal bonded together creates an exceedingly durable sleeve. The sleeves are designed to only hold one credit card per sleeve. It does not matter how you insert a credit card into the sleeve. The entire sleeve is constructed with a 3-layered material (the inside layer is a metal coating). This envelopes and protects the entire card. Protects from RFID scanning. RFID chips are being embedded in many credit cards, ID's, passports, transit cards & more. RFID scanning has now advanced so much that this personal information can be read from a distance.
