GOLPE do CARTÃO de APROXIMAÇÃO: PROTEJA-SE!

Learn how to protect yourself so that no one can sneak a card reader close to your wallet and steal your money! But first, let's understand how this technology works. Inside the machine there's a coil of wires through which electricity enters and exits; this coil acts like an electromagnet, creating a magnetic field. Inside the card there's also a coil, so when you bring one object close to the other, the magnetic field of the machine generates electricity in the card. This allows the card to read the information and send it back to the machine via radio. But there's something called a Faraday cage, a metallic capsule that acts as a barrier to the passage of radio waves emitted by the card. And that's where the counterattack comes in: a simple sheet of aluminum foil can protect you! Did you like it?
