As efforts are made to make advancements, few great inventions are based on the not so popular/important aspects. Barcode System is one such example which has turned out to be a base for yet another revolution in the field of science and technology, its RFID ( Radio-frequency Identification) which is an identification method which relies on storing and remotely retrieving data using RFID components like RFID tags or transponders.
RFID tags come in three general categories; passive, active or semi-passive. Passive tags require no internal power source, thus being pure passive devices, they are only active when a reader is nearby to power them, whereas semi-passive and active tags require a power source, usually a small battery. Some of the RFID standards include ISO 14223/1, ISO 14443 , ISO 15693, ISO 18000-7 though there is no global public body that governs the frequencies used for RFID.
Common applications of extended capability RFID include Industrial Computing, Yard Management, Inventory Tracking and Repair Operations, Cold-Chain Management, Reusable Transport Items Tracking, High Value/High Security Asset Tracking, Military Purposes and other applications where the extended capabilities of RFID are needed.

Computers have already revolutionized the way we live and work. Have they changed the way we think? After reading all posts I think they have. People, why do you write what you hear somewhere, not your own thoughts?
