Radio-Frequency Identification (RFID)

RFID is a wireless technology that uses radio waves to identify and track tags attached to objects automatically. An RFID system typically includes a tag with a microchip and antenna, a reader and a communication interface.The reader sends out a signal that activates nearby tags. These tags respond by sending stored data back to the reader, which can then be processed and used in real time.

Unlike barcodes, RFID tags can be read without a direct line of sight, have read/write capabilities and can identify multiple items simultaneously. In logistics, RFID improves asset tracking, inventory accuracy and supply chain visibility through faster, automated identification of goods.
