A Radio Frequency Identification (RFID) tag is the next generation of barcodes with higher storage capacity and longer detection range. Various types of RFID tags exist, however, you can divide RFID devices into two main classes. Tags that need their power supply are active otherwise, they are passive.
Compared to biometry, smart card, and barcode, RFID tags have the advantages of faster reading speed, better machine readability, and larger storage. Plus, an RFID tag coupled with a reader has many sources of cost reduction such as material cost reduction, labor cost reduction, human error cost elimination, and even sales increase.
