RFID, radio frequency identification, is a technology that has been around for decades but has come a long way in recent years. It identifies and tracks objects using radio waves. The components present in RFID technology consist of an RFID tag that contains a chip, an antenna, and a reader. This blog post will focus on the RFID chip, so if you want to know more, keep reading!
What Is An RFID Chip?
Inside an RFID tag, you can find a microchip that is composed of a microprocessor and non-volatile memory.
This chip can store data and communicate with the RFID reader, also known as a scanner. When an antenna reads a signal from the tag, it sends the information stored in the chip through radio waves back to the reader.
The chip and antenna are barely visible. It is attached to a substrate and encapsulated inside a protective shell to protect it from physical damage.
How Does It Work?
As mentioned, the chip is inside an RFID tag that is attached to the objects that need to be identified.
The chip contains a microprocessor with dedicated software for the RFID application. This processor can receive, store and transmit information according to its programming.
When an antenna reads a signal from the tag, it sends the information stored in the chip through radio waves back to an RFID reader.
The RFID reader is connected to a computer that processes all data received and transmits it to a database for storage. From there, the data is used to track and identify the object to which it was attached.
Where Can An RFID Tag Be Applied?
The RFID tag, which contains the chip, can be applied to many different items. It can be applied to products, pallets, boxes, animals, assets, vehicles, and even humans.
In the business world, it is used to track and stock inventory, assets, identify important shipments and even verify the attendance of employees or students.
One example where RFID tags are widely used is in access control systems such as employee entry badges. With these systems, an employee simply has to wave their badge near a reader, which then sends information stored in the chip to a database, granting them access to secure areas.
What Are The Benefits?
Here are some benefits:
- Small and undetectable
- Can store extensive amounts of information
- Reliable and accurate
- Used in a variety of applications
- Secure and hard to counterfeit
