Metal Rfid Credit Debit card holderA metal RFID blocking card is a thin, credit-card-sized device made from aluminum or shielded alloys designed to fit inside wallets and protect contactless cards from unauthorized skimming. It works by creating a, Faraday cage effect, jamming or blocking, radio frequencies (typically 

) that thieves use to steal data from RFID-enabled credit cards, passports, and ID cards.
