RFID NFC card sleeves | TÜV approved - 12 + 3

Similar to the lead coat for x-rays in a hospital or a Faraday’s cage shield the RFID NFC protective covers 13.56MHz signals and thus prevent your bank cards from being read and the passport through readers. Communication between Reader and bank card / passport is through the protective covers interrupted because the radio waves from the special material of the Protective covers are absorbed and reflected, in a nutshell not be allowed through. As long as your bank card (EC or credit card) or your passport is in the protective cover, as long as it is before reading protected. To use the bank card for contactless payment as usual all you have to do is remove it from the protective card cover remove.
