What Are The Different Types Of RFID Systems?

Radio-frequency identification or RFID generally utilizes the electromagnetic fields to track and identify the goods. Based on the range of frequency, the RFID system is classified into 3 different types. They are LF RFID, UF RFID, and UHF RFID. In Australia, many companies offer such RFID solutions at a low cost.

Here we will discuss all types of RFIDs and their key applications.

What Are The Different Types Of RFID Systems?

UHF RFID:

As the name implies, UHF RFID or ultra-high frequency RFID system has an ultra-high frequency range (300 MHz to 3 GHz). The read range is 12 m. Due to the high rate of data transfer, this is considered as the fastest RFID system. UHF RFID tags are highly cost-effective and they are widely used in pharmaceutical anti-counterfeiting, inventory tracking, etc. Generally, this system is ideal for large volume tags. Two major UHF RFIDs are active RFID and passive RFID.

  • Active RFID –
    The active RFID system has own power source and transmitter. In this system, the read ranges can be extended up to 100 m. Active RFID is expensive as compared to passive RFID. This system is widely used for tracking large assets such as vehicles, machinery, and cargo containers. The sensors of the active RFID help to measure humidity, temperature, vibration, light, etc.
  • Passive RFID –
    In a passive RFID system, batteries are not used. The reader antenna mainly sends the signal to the RFID tag. Passive RFID is cost-effective and flexible. The read ranges of this system are shorter in comparison to active RFID. UHF passive tags are widely used in item-level tracking.

LF RFID:

LF RFID is also known as a low-frequency RFID system. This system can be generally operated in the range of 30 kHz to 300 Khz. LF RFID has lower range of frequency and a slower rate of data reading as compared to other technologies. This system mainly works wells in the presence of liquids and metals. It is widely used in livestock tracking, access control, and other different applications.

UF RFID:

UF RFID generally stands for ultra frequency RFID systems. This system works well between 3 Mhz to 30 Mhz. It always offers 10 cm to 1 m reading distances. Some common applications of ultra frequency RFID systems are data transfer, payment, electronic ticketing, etc. NFC technology or Near Field Communication is generally based on HF RFID system that is widely used for hotel key-card applications and payment cards. Many security systems and proximity card payments using this radio-frequency system.

So, now you have a clear idea about the different types of RFIDs and their applications. Nowadays, this system has become very popular because of its several advantages. By accurately tracking the assets, it can fix many types of business problems.
