Many of today’s top credit cards come with RFID chips. These might be convenient, but it is easier for the data on your chips to be stolen by electronic pickpockets.
You can use an RFID blocker to prevent your data from being stolen by thieves. A blocker can include anything from an aluminum wallet to metal card sleeves inside your existing wallet. Some wallets may come with small chips that can identify RFID readers and block their signals from getting into your cards.
