Criminals are evolving every single day. Their recent craze over the last five to ten years have revolved around stealing debit and credit card information seamlessly. They could have their faces on camera, steal your information, and nobody would be aware. They use little devices (that can be bought off of eBay, as a matter of fact,) and as long as they’re within a certain proximity to you, those devices pick up your information as if you were swiping at a trusted terminal in a store.
An RFID wallet is lined with materials (which vary by the seller) that are laboratory tested and proven to either repel, or render ineffective, any incoming RFID signals that aim to steal your information and sensitive data. When you put these into a wallet, you’re also wrapped the RFID blocking wallet material in leather. Consider it a safe within a safe for extra protection of your assets.
