RFID in RETAIL
INTRODUCTION
Radio frequency identification (RFID) technology uses radio waves to automatically identify physical objects (either living beings or inanimate items). RFID is an example of automatic identification technology. Data on the object (serial numbers, object information, etc.) are stored in the RFID chips embedded in or attached to the object. Using an RFID reader, the identity of the object (data on the object) can be interpreted in a wireless environment.
RFID system is an integrated collection of Tag, Reader, Reader Antenna, Controller, Sensor, Actuator, Host and software system and Communication infrastructure.
MARKET OPPORTUNITIES
IDTechEx find that in 2013, the total RFID market is worth $7.88 billion, up from $6.98 billion in 2012, and growing to $9.2 billion in 2014. This includes tags, readers and software/services for RFID cards, labels, fobs and all other form factors. IDTechEx forecast that RFID market would rise to $30.24 billion by 2024.
RFID Versus Bar Codes
A bar code is a scheme in which printed symbols represents textual information.
Advantages of RFID
Can be read without physical contact and Can sustain rough operational environment
RFID tag can be read up to 100 feet and it can be re-written a large number of times
RFID reader can read multiple tags at a time and line of sight is not required
Can be used to perform other duties like measuring temperature and pressure
Limitations of RFID
Cannot be used in materials made of RF opaque(Metals) and RF absorbents (Water)
Surrounding condition (like having metal and liquids) can impact RFID solution
Improper installation can lead to reading collisions
Immature Technology and a practical limit on number of tags that can read at a time
