MGMT 1000 Lecture Notes - Lecture 3: Radio-Frequency Identification, Magnetic Stripe Card, Animal Identification
MGMT 1000 Tutorial 3 Notes – Voice input and Magnetic stripe readers
Introduction
Magnetic stripe readers
• The process is essentially similar to those already discussed.
• The code is usually then translated to Unicode or ASCII.
• Magnetic stripe readers are used to read alphanumeric data from credit cards and other
similar devices.
• The technology used is very similar to that used for magnetic tape.
• RFID INPUT RFID (Radio Frequency Identification) is an inexpensive technology that can
be used to store and transmit data to computers.
• ‘FID tehology a e eedded i ‘FID tags or sart ards or eve iplated i
humans or animals.
• One familiar type of RFID tag is shown
• An RFID tag can store anywhere from a few kilobytes to many megabytes of data.
• Using radio waves, RFID tags can communicate with a nearby transmitter/receiver that
captures and passes the data as input to a computer for processing.
• Most RFID data is alphanumeric, although it is also possible with some RFID systems to
provide graphical images, photographs, and even video.
• RFID technology is used for a wide variety of applications, including store inventory,
theft prevention, and library book.
• Grocery checkout, car key verification, passport identification, cargo tracking,
automobile toll
• Public transportation fare collection, golf ball tracking.
• Animal identification, implanted human medical record storage, and much more.
Voice input
• It is currently possible and practical to digitize audio for use as input data.
