RFID - Radio Frequency Identification
What is RFID?
RFID is a wireless technology used to uniquely and automatically identify and track objects. This system usually consists of an RFID tag (transponder) and a reader. The label transmits information such as EPC Electronic Product Code to the reader via radio waves. This information can be used for a variety of purposes, such as inventory tracking, asset management or security. [#01 & #02]
RFIDs are generally divided into two main groups: Passive (without its own power supply) and Active (with battery). There are also types that allow reading from various wavelengths and distances. NFCs are, in a sense, considered a subgroup of RFIDs.
Installation and maintenance of RFID systems require a significant financial investment. Startup costs can be high for small and medium-sized businesses.
RFID History [#01 & #02 & #03]
The origins of RFID, like many other technologies and developments, are based on the defense industry. The IFF - Identify Friend or Foe system, developed by the British in the early 1940s, was used to detect enemy aircraft from friendly aircraft. was used to differentiate. This system relied on transponders placed on an aircraft to identify the aircraft by responding to radar signals. This is a fundamental principle of modern RFID technology.
However, commercial applications for civilian use of RFID were not developed until the 1960s and 1970s. During this period, potential applications of the technology in areas such as security, medicine and production began to be investigated.
RFID Alternatives [#02]
a) These are the most commonly used alternatives.
b) They are read with optical readers and are generally lower cost.
c) They require direct line of sight for each reading.
2) NFC (Near Field Communication):
a) Similar to RFID, but designed for shorter distances.
b) Compatible with smartphones and other mobile devices.
c) Especially used for payment systems and personal authentication.
3) Bluetooth and Bluetooth Low Energy (BLE):

Main Areas of Use of RFID
Supply Chain: Inventory management, logistics.
Health sector: Information about medicines and patients (bracelet).
Transportation: Tolls (highways, bridges, etc.), parking lots.
Security: Authentication (School, important campuses, etc.)
Animal tracking: Tracking of domestic or wild animals.
Main Risks of RFID [#02]
1) Security Concerns:
a) There is a risk of data leakage or unauthorized access when reading RFID tags.
b) Advanced encryption and security protocols are required to protect sensitive information.
2) Disposing of RFID tags may increase the amount of electronic waste.
a) It is important to develop sustainable and environmentally friendly waste management solutions.
