Radio-Frequency Identification (RFID):

Radio-Frequency Identification (RFID) Radio-Frequency Identification ( RFID ) is the use of radio waves to read and capture information stored on a tag attached to an object.  A tag can be read from up to several feet away and does not need to be within direct line-of-sight of the reader to be tracked. 

Radio Frequency Identification & Radio Frequency Tag :

Radio Frequency Identification & Radio Frequency Tag Radio Frequency Identification (RFID) – This is the wireless non-contact use of radio-frequency electromagnetic fields  to transfer data, for the purposes of automatically identifying and tracking tags attached to objects.  Radio Frequency Tag (RFT) - The tags contain electronically stored information. Some tags are powered by and read at short ranges via magnetic fields.  Others use a local power source, such as, a battery , or else collect energy from the interrogating electro magnetic field, and then act as a passive transponder to emit microwaves or UHF radio waves.

Benefits of RFID/RFT:

Benefits of RFID/RFT RFID/RFT h elps to improve customer service in terms of availability and fresher product. It allows for automated receiving of goods. It helps firms to receive and deploy merchandize quickly, accurately and inexpensively. It allows more rapid inventory counting. Firms are able to monitor immediate reduction through shrinkages. It helps firms to take stock of full inventory on a daily basis . It allows for easier and more consistent tracking, enabling business owners to have maximum control and visibility over their products at all times.

Radio-Frequency Identification (RFID):

Radio-Frequency Identification (RFID) A RFID system is made up of two parts: a tag and a reader. RFID tags are embedded with a transmitter and a receiver. The tag contains the specific serial number for one specific object.  To read the information encoded on a tag, a two-way radio transmitter-receiver called an interrogator or reader emits a signal to the tag using an antenna. The tag responds with the information written in its memory bank. The interrogator will then transmit the read results to an RFID computer program.

Radio-Frequency Identification (RFID):

Radio-Frequency Identification (RFID) There are 2 types of RFID tags: passive and battery powered.  A passive RFID tag will use the interrogator’s radio wave energy to relay its stored information back to interrogator .  A battery powered RFID tag is embedded with a small battery that powers the relay of information.  When a person uses a handheld RFID reader to scan jeans with RFID tags , he is able to differentiate between two pairs of jeans based upon information stored on RFID tag   Each pair will have its own serial number.   With the handheld RFID reader, the person  can not only find a specific pair, but also can tell how many of each pair are on the shelf and which pairs need to be replenished. 

Radio Frequency (RF) Technologies:

Radio Frequency (RF) Technologies RF tags are superior to bar-coded labels in that they allow significantly more information to be stored and have the capacity to easily update or alter information at any point along the supply chain without having to change the tag. Another advantage over bar-coded labels is its capacity to reliably operate in harsh and dusty environments; C urrent RFID tags are not always reliable and will not work with some products or in certain situations. The main advantage and the greater potential of RFID is its possibility to trace products, collect and access the information about products via RFID tags during each step of the logistics chain.
