This one is a shielded sleeve rather than an open pocket. A PET outer layer over an aluminum inner blocks the RFID signal between a contactless chip card and a reader while the card is in the holder.
Worth being precise about what that does and does not cover: it protects contactless chip cards from being read through a bag or pocket, and it does nothing for cards that are physically swiped, because those send no RFID signal in the first place. It mounts with adhesive so it fits any phone.
