Study Notes
Uses of Chip and PIN Readers
- Payments are made using cards in places such as restaurants, supermarkets, and travel agents.
Advantages of Chip and PIN Readers
- More secure than contactless payments due to PIN verification.
- More robust than magnetic stripe cards.
Disadvantages of Chip and PIN Readers
- Susceptible to fraud if PIN is read by someone else while typing.
Radio Frequency Identification (RFID) Readers
- Use radio waves to read and capture information from tags.
- Can read tags from a distance of several meters, an advantage over barcode systems.
RFID Tag Components
- Microchip: stores and processes information.
- Antenna: receives and transmits data.
Types of RFID Tags
- Passive tags: use reader's radio wave energy to relay information.
- Battery-powered tags: use a small embedded battery to power the RFID.
RFID System Diagram
- RFID tag: connected to antenna.
- Antenna: connected to reader.
- Reader: connected to computer with a double-headed arrow.
