Rfid card

LF RFID 125KHZ

Low frequency(LF) card with frequency from 100 KHz to 125 KHz.The reading distance generally less than 1 meter.

HF RFID 13.56MHZ

HF ( High Frequencey) RFID 13.56MHZ,Read-write Distance：2.5～10cm ,Storage Capacity：2Kbits .

UHF RFID 860-960 MHZ

Ultrahigh frequency 860～960Mhz,Rewritable times: 100 thousand times. Reading and writing: 1-12M.

Have questions about RFID card ? We have answers!

What are the main features available in RFID Card ?

The main characteristics of RFID are as followings:

1: Quick scan. RFID readers can identify several RFID tag reads at the same time.

2: Small size, shape, diversification. RFID is not restricted by the size and shape on the read, and there is no need to read accurately and to cooperate with fixed size paper and printing quality. In addition, the RFID tags can develop toward miniaturization and more diversity form to be adopted in different products.

3: Pollution resistance and durability. The carrier of the traditional bar code paper, so vulnerable to pollution, but RFID for materials such as water, oil and chemicals has a strong resistance.

What's the difference among LF.HF and UHF ?

The general work frequency of low frequency card working sensors is from 120 KHz to 134 KHz, and the common scope is 134.2 KHz. The wavelength of the spectrum is about 2500 m, mainly used in car alarm and no keys—door opening system, as well as automatic parking fees and vehicle management system, and automatic refueling system, access control and security management system, etc.

The working frequency of high frequency card is 13.56 MHz, and the wavelength of the frequency is about 22 m, mainly used in the library, the hotel door lock, pharmaceutical logistics system and large conference staff channel system, etc.

The definition of ultrahigh frequency card is not very same in the world - Europe and parts of Asia defined frequency are 868 MHZ, defined frequencies in North America is between 902 and 905 MHZ, but suggested frequencies is between 950 and 956 in Japan. The wavelength of the spectrum is about 30 cm. They are mainly used in the production automation, aviation package and logistics management system, etc.
