How RFID Reader Works?

How RFID Reader Works?
The explanation of RFID is Radio Frequency Identification. An RFID reader is a device that is being used in many places to track data instantly in real-time. The demand for RFID readers is increasing day by day. It offers many advantages to the industrial sector. There are many contributions of RFID readers in many situations. To make the reader more beneficial, you have to choose the right category for yourself. In this article, you are going to know details about RFID readers. It will make an idea for you. Let’s jump into it.

What is RFID Reader?
An RFID reader is part of the RFID system. It is the key to the RFID system. It works as a transmitter, and it receives radiofrequency. It communicates with tags. There are two distinct types of divisions of RFID readers.
1. Fixed RFID Readers
The Readers that stay in one particular location are fixed RFID readers. Fixed readers are mainly integrated readers. They have built-in antennas. There is a port system for an external antenna connection with fixed RFID readers.
Benefits of Fixed RFID Readers
• It has an automated inventory tracking system. As a result, you don’t need to be concerned about switching on or off. If you want to know, how much inventory comes into your area per day, fixed readers will automatically keep tracking it. So, you don’t have to worry at all.
• Fixed RFID Readers have always kept the power on. So it can provide real-time monitoring. It works continuously. That is why the fixed reader is known as a workhorse.
• A fixed reader can connect up to 8 external antennas as it has multiple ports to connect. Even if anyone wants to join more than eight, he can use multiplexor to add more antenna.
• It has a broad read range. It can cover a large area within the blink of your eyes.

2. Mobile RFID Readers
Mobile RFID readers help to increase the flexibility of reading RFID tags. It is a handheld reader. There are two types of mobile RFID readers included devices.
 Mobile Computing Devices: Mobile computing devices have the reader of an onboard computer.
 Sleds: This mobile reader uses a wireless connection with smart devices.
Benefits of Mobile RFID Readers.
• Mobile RFID readers are transportable. They are light in weight and easy to carry. That is why anyone can take it with them wherever they go.
• Mobile readers don’t require any installation hassle. Just turn on the reader, and it will start to read RFID tags.
• Mobile readers are easy to use. They have the function to convert the codes and transmit them.
How does RFID Reader Work?
An RFID reader is the device of the receiver, decoder, and transmitter. It can work as a transmitter as well as a receiver. When you power on the reader, the oscillator located into the reader starts to generate signals within a fixed frequency range. If the signal is less strong to cover, then the RFID uses the amplifier to amplify the signal and make them stronger.
Then the signal goes into the antenna. The Internal antenna covers the electrical signal into electromagnetic waves. Now the reader can detect the RFID tags that come in the proximity of the reader. The incoming tags detect the signal through a coil. The coil works as a converter. It converts the received RF signal into an electric signal. These electric signals power up the chip of tags.
The microchip starts the function of sending a unique ID. Besides, when the wave comes back from tags through an antenna. The demodulator in the reader decoded the signals and receive the original data. In summary, RFID readers decode signals and transmit them. Thus it works as a transmitter. Again, when it receives signals and decodes them, the reader works like a receiver.
Usage of RFID Reader
1. Business

RFID readers are necessary for business as it tracks the supply chain. As a result, there will be no chance to miss any goods. For business purposes, you may need to go to many places. In that case, you can carry a mobile RFID reader. Using a fixed reader is a lengthy process for a traveling-related business. But if your business location is fixed. You need to use a fixed reader.

2. Distributed Center

As the reader has an inventory track system, it can record the product list. It tracks all the expenses related to your product distribution system. For distribution centers, fixed readers are the best choice.

3. Healthcare

RFID readers are mandatory for the healthcare system. It is necessary to identify the data of patient ID, blood group, cost of medical test, and much medical staff. RFID readers help to track all the data to provide a relaxed environment in the hospital for the patient.

4. Manufacturing Industry

Readers are a must for the manufacturing industry. It tracks the number of materials and keeps the manufacturing system moving on. It protects the security and avoids error while the manufacturing process is going on.
Things You Should Know Before Selecting RFID Readers
Whenever you use a device, you need to make sure that you are choosing the right one for you. And you need to think about some perspectives.
 Before selecting a reader, make sure how much frequency range you will need to cover your area.
 You have to ensure a perfect environment for the reader device. If your area is sensitive to electronics, you have to recover it.
 You have to select the location where you will place the reader device. You have to choose a safe place for the reader where it can be safe from heat and water.
 Always check the quality before choosing an RFID reader. Is it slow-moving or fast going? What type will be better for you? Ask yourself before buying it.
In Conclusion
The usage of RFID technology system is growing fast as it has a lot of advantages. The electronic device will benefit you if you can bring one according to your requirement. The RFID reader has many categories depending on its frequency range and efficiency level.
