RFID blocking in plain words: what the lining does and does not do
Plenty of wallet marketing treats RFID like a monster under the bed. We would rather explain the mechanics and let you decide how much you care.
The thing being blocked
Tap-to-pay cards and many ID badges carry a tiny chip that answers radio at 13.56 MHz when a reader wakes it up. That is what lets you tap instead of swipe. A skimmer is just a reader in the wrong hands, waved close enough to a pocket to start that conversation uninvited.
The thing doing the blocking
Inside our lined models sits a thin metallic mesh between the leather and the fabric. Radio at card frequencies cannot usefully pass through it, so a closed wallet simply does not answer. There is no battery, nothing to switch on, nothing to wear out. You cannot feel the layer in the hand.
What it does not do
- It does not protect a card while you are holding it out to pay
- It does nothing about online misuse of a card number typed into a form
- It does not block magnetic stripes, which never spoke radio to begin with
Do you need it?
Documented skimming in the wild is rare, and card networks shoulder fraudulent taps in most places. We build the lining because it costs nothing in thickness or weight, so the question becomes: why not. If it lets you stop thinking about the subject entirely, it has done its job. Models with the lining say so right in the spec line.
