What Is The Difference Between Metal And Non-metal Rfid Tag?

A standard RFID system consists of three main components: an RFID reader, RFID tags (also known as RFID tags or RFID tags), and a software system that connects the two. The RFID tag contains a chip and an antenna that work together to achieve wireless communication. The reader sends an electromagnetic signal to the tag, activating the chip on the tag. The chip sends the stored information back to the reader, thereby achieving data transmission.

 

The RFID anti metal tag adds an anti metal material on the existing basis, which can prevent the tag from failing to bond with metal objects. The tag made of this material is called an RFID anti metal tag. Anti metallic materials are electronic tags packaged with special anti magnetic absorbing materials, which technically solve the problem of electronic tags not being able to adhere to metal surfaces. The product is waterproof, acid resistant, alkali resistant, and collision resistant, and can be used outdoors.

 

2. RFID anti metal tag

RFID anti metal tag is a tag designed specifically to deal with metal surface interference. The metal surface reflects and absorbs RFID signals, causing signal transmission interruption or attenuation, making it impossible for tags to read or write data normally. To address this issue, the anti metal tag adopts a special design and material to reduce the impact of the metal surface on the signal.

Anti metal tags typically use low frequency (LF) or ultra-high frequency (UHF) technology. LF tags have a strong ability to penetrate metals due to their low operating frequency, but their data transmission rate is slower. UHF tags have higher data transmission rates, but their anti-interference performance against metals is relatively poor. Therefore, when selecting RFID anti metal tags, the selection should be based on specific application scenarios and metal surface characteristics.

 

3. RFID non-metal tag

Corresponding to anti metal tags is RFID non anti metal tags, also known as ordinary RFID tags. These types of labels are prone to interference when working on metal surfaces, resulting in data reading failures or instability. Therefore, when using non-metallic labels, it is advisable to avoid directly sticking them to the metal surface. It is possible to choose to stick them on non-metallic pads to reduce contact with the metal.
