RFID Controllers
About RFID controllers
RFID controllers operate on the principle of Radio Frequency Identification (RFID), a technology that uses radio waves to identify objects equipped with tags when they approach a reader. Although various system types exist, the underlying concept is the same: each tag carries a unique serial number that allows the controller to distinguish it from all others.
Our RFID controllers are engineered for precise access control and identification, utilizing robust radio-frequency technology to deliver secure, fast, and contactless operation across a wide range of industrial and commercial applications.

RFID technologies and operating modes
RFID controllers technologies
Low-frequency systems (125 kHz, EM4102)
Our 125 kHz RFID controllers operate with passive EM4102-compatible tags. These systems are known for their robustness and virtually maintenance-free operation. When a tag approaches the antenna, it is powered by the electromagnetic field and transmits its unique identifier to the controller.
High-security DESFire systems (13.56 MHz)
For applications that require stronger protection, we offer controllers based on MIFARE DESFire technology. These systems provide advanced cryptographic security, mutual authentication, and secure data storage, making them suitable for high-security environments.
Operating modes
P — Pulse mode
Activates the relay for a preset time when a valid tag is presented. Ideal for door releases, elevator panels, and basic access control.
F — Flip-Flop mode
Toggles the relay output on each valid tag. Suitable for machinery on/off control and industrial switching applications.
T — Terminal mode
Reads the tag and sends its ID over RS232 for external decision-making by PC or PLC. Used in integrated automation and custom access control systems.
Key points
The most common RFID systems use passive identification tags, which have become popular due to their virtually maintenance-free operation. When a passive tag approaches the antenna, it is energized by the electromagnetic field and transmits its unique serial number to the reader.
We design and manufacture radio-frequency identification controllers operating at 125 kHz, compatible with EM4102 tags, as well as controllers that support high-security MIFARE DESFire contactless technology.
DESFire-based systems offer advanced cryptographic protection, mutual authentication, and secure storage, making them suitable for applications requiring a higher level of security.
All controllers feature a serial communication interface that allows adding or deleting tags and modifying device settings. For easy configuration, we recommend our LockyMonitor3 software, which is free to download and use.
Some of our RFID controllers can operate as stand-alone units, suitable for access control, equipment usage monitoring, and control of electrical or electronic systems.
Other models support real-time communication with a PC or PLC through the built-in serial interface. In such cases, third-party software determines tag validity, allowing integrators to build small-scale access control systems, scheduled access to machinery, time-attendance systems, and similar solutions.
