  • Q: What is a Dual Frequency (UHF + HF) RFID Card?
    A: It is a smart card that contains two separate and independent chip-and-antenna systems within a single card body. One system operates on the Ultra-High Frequency (UHF: 860–960 MHz) for long-range identification, while the other operates on High-Frequency (HF: 13.56 MHz) for short-range, secure interactions.
  • Q: How do two antennas work in one card without interfering with each other?
    A: Through sophisticated engineering. During manufacturing, the two antennas are designed with different shapes and are physically positioned on separate layers within the card to minimize signal overlap and crosstalk. This specialized design ensures that each chip-and-antenna pair functions reliably in its designated frequency without interfering with the other.
  • Q: How is this different from a “Dual Interface” card?
    A: They are completely different technologies. A Dual Frequency card has two separate chips for two different frequencies (UHF + HF). A Dual Interface card has one single chip that supports two communication methods (contact + contactless).
  • Q: What is the performance and read range of a Dual Frequency Card?
    A: Each frequency performs as it would in a single-frequency card. The UHF component offers a long read range, typically up to 10 meters, ideal for vehicle access or inventory tracking. The HF component works within a short range of 5–10 cm, perfect for secure tap-and-go applications like door access or payments. Advanced anti-collision technology ensures reliable operation for both frequencies, even in busy environments.
  • Q: Do I need a special “dual frequency” reader for these cards?
    A: No. You use your standard, separate readers. The card is passive and will only respond to the reader that communicates on its frequency. It will activate the UHF chip when presented to a UHF reader, and the HF chip when presented to an HF/NFC reader.
  • Q: Are these cards compatible with standard RFID systems?
    A: Yes. The cards are designed to be fully compliant with global standards, such as ISO/IEC 18000-6C for the UHF part and ISO/IEC 14443 or 15693 for the HF part. This ensures compatibility with most standard readers. We can help you confirm compatibility with your specific system.
  • Q: Can Dual Frequency RFID Cards work with NFC-enabled phones?
    A: The HF component (13.56 MHz) of the card may work with NFC-enabled phones for basic tasks, depending on the specific chip (e.g., an NTAG® series chip) and the phone’s capabilities. The UHF component will not work with NFC phones and requires a dedicated UHF reader.
  • Q: Why would my organization need a Dual Frequency Card?
    A: The primary benefit is consolidation. They are perfect for environments that use two different RFID systems but want to provide users with a single, convenient credential. The most common use case is a corporate or university campus that uses UHF for long-range parking access and HF/NFC for secure building access, library checkout, or payments.
  • Q: Can Dual Frequency RFID Cards be customized with our logo?
    A: Absolutely. Our cards are made from high-quality PVC or rPVC and support full-color printing for your logos, text, or any custom designs, making them ideal for branded corporate, campus, or membership cards.
  • Q: Are these cards durable enough for daily use?
    A: Yes. Despite containing two sets of electronics, they are manufactured to the standard CR80 size and thickness. The robust PVC material resists bending, cracking, and scratches, making them suitable for everyday use. They are also water-resistant and operate reliably in variable climates.
  • Q: How are Dual Frequency cards secured against cloning or unauthorized scanning?
    A: Security is handled by each chip individually. The HF component can use high-security chips (e.g., MIFARE DESFire®) with advanced encryption, while the UHF component can be protected with access and kill passwords. We ensure secure chip configurations to enhance protection against cloning risks.
