Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. RFID is one method of automatic identification and data capture.
Unlike a barcode, you don’t need to search and read tags one by one, multiple RFID tags may be scanned and read via just a single RFID reader. As such, RFID technology can overwhelmingly shorten the time to count inventory.

As the UHF passive RFID (RAIN RFID) is capable of collective reading from a certain distance without a battery. In just 2017 alone, over 12 billion RFID tags were shipped worldwide.
