Explain what pin pad and chip readers are and how they are used.

A pin pad is a pad that has numbers on it and is normally used to input a password onto. You would use these on the doors of your home or a safe or something you keep your valuables in. A chip reader is a device that reads a microchip (for example, a chip is something you would find in your credit card) and it read the chip to access what is in it (normally).
