The smooth introduction of Radio-Frequency Identification (RFID) technology into our everyday routines has revolutionized various sectors by providing effective means of monitoring and controlling objects and data. RFID cards are at the centre of this technological revolution, with applications ranging from inventory management and payment systems to access control. This blog will look at various types of RFID cards and their unique features.
Understanding RFID Frequencies
RFID systems function using three distinct frequencies: ultra-high frequency (UHF), high frequency (HF), and low frequency (LF). The particular requirements of the application and the surrounding circumstances determine the frequency to be used.
1. Low-Frequency (LF) RFID:
LF RFID systems typically operate at 125 kHz or 134 kHz, with a frequency range of 30 kHz to 300 kHz. These cards are resistant to outside interference because of their short reading range of about 10 cm. LF RFID complies with ISO 14223 and ISO/IEC 18000-2 standards and finds use in access control and animal tracking.
2 . High-Frequency (HF) RFID:
HF RFID systems typically run at 13.56 MHz, although they can have frequencies as high as 30 MHz. The reading range (10 cm to 1 m) and data transfer speed are balanced on these cards. Applications utilizing ISO 15693, ECMA-340, ISO/IEC 18092, and MIFARE include tickets, payments, and data transfers.
3. Ultra-High-Frequency (UHF) RFID:
UHF RFID systems follow the UHF Gen2 standard (860 to 960 MHz), which covers frequencies from 300 MHz to 3 GHz. UHF RFID technology offers quick data transmission and a read range of more than 12 meters, making it perfect for medicine identification and retail inventories. EPC Global Gen2 (ISO 18000-63) regulates the global standard.
4. Passive and Active RFID Systems
RFID cards are further categorized as passive or active based on their power source.
- Passive RFID Cards:
These cards are stable and cost-effective since they run on the energy that the RFID reader transmits. They are used in logistics, inventory control, and access control.
- Active RFID Cards:
Active RFID cards actively transmit signals because they are equipped with an internal power source, typically a battery. They are appropriate for real-time tracking of valuable assets and vehicles and have an extended read range (more than 100 meters).
Conclusion
RFID technology offers a wide range of solutions to meet the unique requirements of different industries and applications. Every form of RFID card has a certain function, whether it’s the extended read range of UHF RFID cards, the versatile balance of HF RFID cards, or the short-range capabilities of LF RFID cards. RFID card applications will grow further as technology advances, enhancing the productivity and creativity of many industries. In this fast-evolving RFID era, knowing the subtleties of each type of RFID card enables individuals and organizations to select the technology that best suits their needs.
