What Is The Difference Between High Frequency Cards and UHF RFID Cards?

Both high-frequency card and ultra-high frequency card can play the role of identification, object tracking and information collection. The RFID system composed of electronic cards, readers, antennas and application software is directly connected with the corresponding management information system, so that every item can be accurately identified and tracked.

The main difference between high-frequency electronic labels and ultra-high-frequency electronic labels is the difference in working frequency, which makes the application fields different.

Ultra high frequency RFID cards (UHF), with operating frequencies between 860MHz and 960MHz, can be divided into active cards and passive cards. When working, the RF card is located in the far-field area of the UHF reader antenna radiation field. The coupling mode between the RFID card and is electromagnetic coupling. The UHF reader antenna radiation field provides RF energy for the passive card to wake up the passive card.

The reading distance of Ultra high frequency RFID card (UHF card) is generally more than 1 meter, typically 4-6 meters, up to more than 10 meters. It has three main advantages: strong security and confidentiality; It has strong penetration performance, can be used in harsh environments, and has large data memory capacity.

UHF RFID electronic card (UHF) is widely used in asset management, warehousing management, supply chain, logistics management and other aspects because of its high recognition sensitivity, multi card reading, long reading distance and fast data transmission speed.

The typical working frequency of high-frequency RFID card (HF card) is 13.56MHz, which is generally passive. When the card and data exchange, the card must be located in the near-field area radiated by the RFID reader antenna, and the reading distance is generally less than 1 meter.

High frequency RFID cards (HF) have strong ability to penetrate non-metallic objects and are not subject to radio frequency interference. They can be widely used in library management systems, fixed asset management systems, intelligent shelf management, clothing production lines and logistics systems.
