The RFID Card Holder is a slim credit card holder that protects your ID and credit cards from digital skimmers. The 210D exterior makes it sturdy enough to be a stand-alone wallet, while the flat design allows it to be stored in your favorite wallet. Four internal sleeves can hold multiple cards or folded cash, while a diagonal elastic loop keeps it closed. It's also a super handy size that will no doubt become your everyday go-to. Features Lined with RFID-proof fabric for digital credit card protection Sturdy 210D® exterior Four internal card sleeves Please note: RFID-protected products will only offer protection against scanning of the very low-power signal emitted by a credit card or passport chip. They will not block a higher power radio signal (for instance a Smartphone or a Car-Key or Garage remote)
