Here, we provide four frequency band cards: UHF, HF, LF, and dual-band.

So what are the differences and advantages between them? What scenarios are they applied in? How to choose the card you need？

• UHF frequency card: The operating frequency of UHF cards is usually between 860 MHz and 960 MHz. They have a long recognition distance and high safety performance, reaching several meters to tens of meters. They are used in scenarios that require large-scale item identification and tracking, such as logistics management and vehicle identification.
• HF card: This type of card usually operates at 13.56 MHz. It has a large capacity and good confidentiality at a distance of 10 cm, so it can be used in payment, access control, and other scenarios.
• LF cards have less interference with metals and liquids and can work stably in harsh environments, so LF frequency is commonly used for animal identification and vehicle access control. Compared to UHF, HF is cheaper in price. However, its safety is relatively low. 125Khz ID cards usually need reading only,but they can meet basic needs such as community access control systems and library borrowing systems.
• Dual-frequency RFID cards: Compared to single-frequency RFID cards, dual-frequency RFID cards have higher flexibility, stronger anti-interference ability, better security, and a wider range of applications. However, the cost of dual-frequency RFID cards may be relatively high.
