RFID (Radio Frequency Identification) is a technology which works on radio frequency and it is used for auto identification of objects and personnel. There are multiple frequencies of RFID based on close proximity (a few centimeters) to long range (many meters). RFID is replacing the traditionally used barcoding due to its efficiency and ease of use. The biggest advantage of RFID is it is capable of scanning and detecting multiple objects at the same time from a distance, making it the most efficient way of tracking assets and resources. RFID now comes in 100’s of different forms of material and dimensions: from stickers, metals, plastics to cloth based.
