Introduction to RFID technology

Radio Frequency Identification (RFID) is a rapidly evolving technology that employs electromagnetic fields to automatically identify and track tags attached to objects. The tags contain electronically stored information that can be read from up to several meters away, and unlike a barcode, the tag does not need to be within the line of sight of the reader, so it may be embedded in the tracked object.

RFID technology has two main components: the RFID tag or smart label and the RFID reader. The RFID tag, which may be as small as a grain of rice, contains an integrated circuit for information processing and storing, and an antenna for receiving and transmitting the signal. The RFID reader, on the other hand, is a device that uses radio waves to communicate with the tag and read or write data to it.

These tags come in two forms—active RFID tags, which have a power source and can transmit signals autonomously, and passive RFID tags, which require an external source to provoke signal transmission. Active RFID tags are typically used in large-scale tracking scenarios where long-range reading is necessary, while passive RFID tags are more commonly used in logistics and retail environments for tracking goods and inventory.

RFID technology has a diverse range of applications and is used in industries such as retail, logistics, manufacturing, transportation, healthcare, and more. Its ability to significantly increase efficiency in tracking assets and managing inventory is one of the main reasons for its widespread adoption.
