What is RFID? ? Radio Frequency IDentification (RFID) is a next generation of Auto Identification and Data Collection (AIDC) technology which helps you automate business processes. ? RFID is an auto-identification technology which is used for tracking items with a tag on it which sends data to readers through radio waves. These tags make the item to speak about its identity, activity, location, and data stored inside through readers and finally to the application software to make the information useful. ? This automation can provide accurate and timely information without any human intervention. Access to such information where you can individually identify each one of the tagged items uniquely and helps in improving your processes and also to make an informed decision. ? The tag is made up of a microchip with the unique identification number and the antenna to be able to transmit this data to the reader wirelessly. ? RFID tags have high data capacity and can include manufacturer, batch no., ownership, destination, history etc. depending on the application needs. ? The amount of storage available on the tag ranges from 16 bits to as high as several thousand bits. Active and Passive tags Passive tags are batteryless and transmit data only when energized by the reader. Active tags are able to transmit data using their own battery power. Read ranges are more for active tags than for passive tags but are costlier for their extra capability. Therefore active tags are used for high value items and for longer reading distance.Advantages ? No line of sight ? Contactless ? Improved read range ? Ability to write data ? High data storage capacity ? Can read multiple item ? Suitable for harsh environment ? No human intervention
