RFID been used in multiple applications most popular are:- In hospital Patient/ medical equipment
tracking- In marketing and supply chain
replacing the barcode.- In security monitoring and tracking
devices GPS- In computer and wireless network as
in the antenna

• low frequency (blow 1 MHZ), universal frequency required worldwide for scientific instrumentation
• 13.56 MHZ
• and ultra high frequency which is over 800 MHZ

Omnidirectional Antennas:which radiate signal could be more or less in all directions. • These are used when the relative
position of the other station is unknown or random.
• also used at lower frequencies where a directional antenna would be too large, or basically to cut costs in applications where no need for a directional antenna .
The Transmission Differences

Directional or Laser-beam Antennas:• which are intended to specially
radiate on a precise focus direction or directional shape.
• With directional antenna we can expect an effective beam width
• however! The beam width decreases as distance increases

• The RFID or Radio Frequency Identification, has been recognized as a key element to the Network, globally.
• As the information can be accessed at any time any where via the network. although its a fantastic innovation it dose have its drawback
• Privacy Issue is the main concern, as the technology have the capability to pinpoint the locations a privacy will always be a an issue
