Study Notes
RFID and NFC
- An RFID reader uses radio waves to read information on a tag
- RFID can track various things such as:
- Times of runners in a marathon
- Location of people and items
- Lift tickets of skiers
- Inventory management
- Temperature and pressure of tires
- Library book checkout
- Purchases and payment at toll booths
- Access to rooms or buildings
- NFC (Near Field Communication) is a protocol based on RFID for close-range communication between devices
- NFC has a short range of usually only an inch or less
- NFC can be used for commerce, user identification, and security
- Google Wallet uses NFC for MasterCard PayPass transactions
Input Devices
- Input devices translate data into a form that the system unit can process
- Examples of input devices include:
- Keyboards (traditional, laptop, virtual, and thumb)
- Pointing devices (mouse, touch screen, game controller, stylus)
- Scanning devices (optical scanners, flatbed scanners, document scanners)
- Image capturing devices (digital cameras, webcams)
- Audio-input devices (voice recognition systems, microphones)
- Biometric devices (fingerprint readers, face recognition systems, hand geometry systems)
Pointing Devices
- Provide an intuitive interface for pointing and clicking
- Examples include:
- Mouse (optical, wireless, touchpad)
- Touch screen
- Stylus (pen-like device for tablets)
- Game controllers (joysticks, gaming mice, game pads)
Scanning Devices
- Convert scanned data into a form the system unit can process
- Examples include:
- Optical scanners (flatbed, document, portable)
- Barcode readers (wand, hand-held, UPC, MaxiCode)
- RFID readers
Image Capturing Devices
- Create or capture original images
- Examples include:
- Digital cameras
- Webcams
Audio-Input Devices
- Use a microphone, sound card, and special software for voice recognition
- Examples include:
- Voice recognition systems (Siri, Cortana, Google Now)
Biometric Devices
- Authenticate a person's identity by translating a personal characteristic into a digital code
- Examples include:
- Fingerprint readers
- Face recognition systems
- Hand geometry systems
- Voice verification systems
- Signature verification systems
- Iris recognition systems
