INFO

The hallmark of these dual-frequency RFID cards is their unmatched versatility. By merging the features of two distinct chips, users benefit from the combined advantages of both frequencies.

The 125 kHz TK4100 chip excels in basic identification and tracking applications, offering consistent and reliable reads, even in less than ideal environments. On the other hand, the Mifare Desfire®  EV3 4k chip operates at a higher frequency and provides a robust storage solution, catering to more sophisticated data and security requirements.

Dual-frequency RFID cards are the result of integrating two powerful technologies into one practical platform. Each frequency - 125 kHz and 13.56 MHz - provides its advantages, and their combination allows for exceptional flexibility and efficiency. 

The cards are designed to be durable enough for daily use, while also being sophisticated enough to ensure a high level of security and functionality.

These cards can be used for a broad range of applications, including building access control, employee tracking, automated payment systems, inventory management, and more. Integrating two chips onto one card reduces the need for multiple cards for different purposes, enhancing user convenience and cutting down costs for organizations.
