Comprehensive explanation of common types of dual-band cards
With the continuous upgrading of intelligent security and intelligent management needs, dual-band cards have become a common choice for high-end access control and identity authentication systems in many enterprises, residential, industrial and IoT fields due to their compatibility with multiple frequency bands, stable data transmission and strong anti-interference ability. This article will give you a comprehensive understanding of the diversity and professional applications of dual-band cards from the aspects of the definition, main types, typical application scenarios and purchase points of dual-band cards.
What is a dual-band card?
A dual-band card refers to a contactless smart card that can support two different frequency bands (such as 125kHz low frequency and 13.56MHz high frequency). It has two sets or composite antennas built in, which can be flexibly compatible with terminals such as access control systems and attendance equipment of different frequencies, greatly improving the applicability and management efficiency of the card.
Common dual-frequency card types
LF+HF composite card
This type of card integrates low-frequency (LF 125kHz) and high-frequency (HF 13.56MHz) dual coils, which are compatible with traditional low-frequency access control and high-frequency intelligent identification devices, and is used in scenarios where new and old systems coexist.
IC+ID dual-frequency composite card
Integrates IC chip (high-frequency communication, encrypted storage) and ID chip (low-frequency reading and writing, simple identification) in one card to achieve composite applications. Such as some smart office buildings, campus one-card, etc.
NFC dual-frequency card
The 13.56MHz high-frequency card that supports NFC (near field communication) function is combined with LF/ID card, which can communicate with new mobile phones and mobile payment devices, and also retains compatibility with traditional access control and attendance terminals.
Customized dual-frequency customized card
According to customer needs, it supports multiple protocols or multi-function integration such as magnetic stripe, QR code, Bluetooth, etc. to meet the exclusive needs of special industries and scenarios.
Typical application scenarios
Office building and enterprise park one-card: realize "one card for access control, attendance, parking, catering and other scenarios", and smooth transition between old and new systems.
School and hospital management: facilitate identity authentication of teachers, students and medical staff, secure partition access, and achieve hierarchical management of visitors and personnel.
Industry and logistics: suitable for multi-band identification scenarios such as warehouse access control, personnel positioning, and item traceability to improve production and circulation safety.
Smart community and residential area: integrate access control, elevators, public areas and other functions to improve residents' safety and convenience.
Notes on choosing dual-frequency cards
Compatibility matching: confirm the type of dual-frequency card purchased (such as LF+HF or IC+ID) according to the actual system frequency deployed.
Security: high-frequency chips with encryption functions are preferred, and data protection protocols are used to prevent copying and illegal cracking.
Durability: high-quality PVC materials and precision packaging improve the card's wear resistance and drop resistance, and are suitable for high-frequency application environments.
Personalized customization: supports personalized printing and data writing such as LOGO, QR code, serial number, etc., to enhance corporate image and management efficiency.
