What is a RFID Sleeve?
In today's electronic age, cards namely credit cards remain in your purse or wallet but did you know they can still be scanned by readers and card skimmers.
RFID blocking sleeves show to reduce the readers transmitted signal power, thus preventing the microchip in the RFID card from working; this means your data is safer. Essentially RFID readers transmit signals which powers up the microchip in the card, when the microchip in the card powers up it then sends data back to the reader.
This card sleeve can be used to block RFID scanning on cards which store electronic information including credit cards, security cards, ID cards, membership cards etc
