As a rule, RFID protection cards (RFID blockers, blocker cards) are the size of a credit card and are intended to prevent unauthorized reading of credit and giro cards as well as identification documents (e.g. carried in a wallet) – which are now usually equipped with Near Field (NFC) technology.
Whether the blocker cards are electrical devices as contemplated by the Electrical and Electronic Equipment Act (ElektroG) depends on their internal structure. RFID blocker cards with an integrated chip are active cards that send meaningless signals to readers. RFID blocker cards with an integrated aerial are passive cards that are supposed to interfere with readers using the built-in aerial. Both types of Blocker cards, cards with chips or aerials, are electrical devices and fall under category 6.
In contrast, RFID blocker cards that contain neither a chip nor an aerial, but only a metal foil to shield an electromagnetic field, do not fall under the ElektroG as they do not constitute electrical devices.
