Contactless cards offer protection against card skimmers that fraudsters can install inside card readers on ATMs and payment terminals. Because you don’t insert your card into a card reader, a “skimming” or “shimming” device can’t access your card’s info. Although scanning a card with a mobile skimmer while the card is in your wallet is theoretically possible, it is not common. Skimmers have to be very close to your card to work, so using an RFID wallet can’t take the place of being careful and practicing safe habits when you’re out and about making purchases. An RFID wallet can offer an added layer of protection, but using a contactless card actually reduces the likelihood that your card will ever be skimmed.
