Keep your cards in a safe space to ensure that they do not get lost and also to ensure that your cyber hackers are not able to steal your identity with this Administer RFID Money Clip Card. This card is made of 840D polyester material with 210D polyester Lining. This card also features a rather slim and portable look to make it easy to carry around. When your cards are placed in this card, cyber hackers are not able to retrieve information from your cards as the RFID blocking system prevents this data transfer. This protective mechanism is only useful for contactless chip cards and not those that are swiped.
