ELATEC TWN4 MultiTech 2 LF HF-P

In a busy logistics hub, a technician snaps the ELATEC TWN4 MultiTech 2 LF HF-P into a custom handheld terminal. Within seconds, the module reads an EM4100 badge for door access, then switches to a MIFARE DESFire card for secure payment—no extra hardware needed. This OEM PCB module brings dual-frequency RFID to embedded systems, supporting both 125 kHz/134.2 kHz LF and 13.56 MHz HF transponders. It connects via USB, RS232, or TTL, and works with Windows, Linux, Android, and macOS. Field-updatable firmware and AES128 encryption keep deployments future-proof and secure.

Why choose it

Engineered for OEM integration, the TWN4 MultiTech 2 LF HF-P eliminates the need for separate LF and HF readers. Its compact PCB design fits into space-constrained devices, while the broad transponder support covers legacy and modern credentials. The module's low power consumption and wide temperature range suit industrial and outdoor use. With multiple host interfaces and driver modes, it adapts to existing architectures without redesign.

Ideal use cases

• Access control systems for buildings and vehicles
• Time and attendance terminals
• Handheld RFID readers for inventory and asset tracking
• Point-of-sale devices accepting contactless payments
• Industrial automation and IoT gateways

Good to know

The module includes an integrated buzzer and two LEDs for user feedback. Firmware can be updated in the field via the host interface, ensuring compatibility with new transponder types. AES128 encryption secures host communication. Typical read range is up to 80 mm for HF and 60 mm for LF, depending on transponder and antenna environment. Power consumption is under 100 mA idle and under 200 mA active.
