RFID

What is RFID?

RFID or Radio Frequency Identification is a technology that uses electromagnetic fields to read an RFID tag that is attached to an object. Unlike a barcode, an RFID tag does not need to be placed within the line of sight of a reader. Instead, when an RFID reader is placed near an RFID tag, the RFID tag transmits information using its antenna.

An RFID tag often stores information such as a unique serial number or some product-related information such as batch number, production date, etc. When an RFID tag is attached to an object, the object can be easily tracked through warehouses or during production.


In this article, we will discuss:

  • What is RFID?

  • What is an RFID tag?

  • What are the different types of RFID systems?

  • Where is RFID technology used?

  • What is the difference between RFID and NFC?
