Dual RFID Tags

Dual RFID Tags

The Dual Tag contains two different frequency IC chips. The characteristics differ depending on the frequency and specifications, and advanced technology is required for making these tags.

E-Garde has developed the Dual Tag with advanced functions and a guaranteed distance and range. The tag can be easily integrated into existing systems, which saves both time and money.

The potential uses of this tag are vast. The Dual Tag supports both medium-range communication in the UHF band and also supports NFC functionality. This can be used in combination with smartphones, making it possible to easily connect people, things and data.

In the future, efficiency will be emphasized even more in many countries, where there is an acceleration in the decline of the working population. Contactless tag systems, which do not require battery replacement and can be used for a long period of time, are expected to play an increasingly significant role.

Advantages & Key Facts

  • Communication attenuation can be surppressed even via a small antenna by electrically coupling the HF and UHF band antennas.
  • Operational Frequencies:
    • HF (13.56 MHz)
    • UHF (860-960 MHz)
  • Long read range
  • HF and UHF IC chips can be combined freely, allowing easy integration into existing systems with existing hardware.
    • The HF IC supports MIFARE and various NFC chips
    • The UHF IC supports multiple IC types.
  • E-Garde designs antennas for other IC chips upon request.


The Dual Tag antenna is E-Garde's own design and received a patent in the year 2016 in Japan. International patents have also been obtained in Germany, France, Italy, America and China.


The Dual Tag is designed for multiple applications including:

  • Warehouse Management
  • Process Management
  • Logistics Management
  • Inventory Management
  • Acquisition of Product Information
  • Managing Goods from Production to Consumption
  • Security / Authentication
  • Access

The HF band can be used for security authentication. The UHF band can be used for long-distance authentication. In factories, for example, HF employee ID cards can be used to grant access at security gates for attendance management. The UHF band can be used for access control at large gates and for vehicles. NFC-enabled smartphones enable personal authentication, advertising, electronic payment systems, URL guidance and can be used to improve traceability of products from producers to consumers.
