Access-control and attendance systems often need to support multiple credential types while fitting into compact host equipment and existing building infrastructure. The TWN4 Palon Compact M reader module supports LF and HF RFID, NFC and Bluetooth Low Energy authentication. It can read more than 60 RFID technologies, allowing one platform to handle legacy badges, smart cards and mobile credentials.
On-board LF and HF antennas and a compact twin-stack PCB design simplify integration into access-control terminals, time clocks and industrial authentication equipment. Typical 125kHz and 13.56MHz read range is up to 100mm, depending on the environment and transponder, while Bluetooth LE communication can extend to several meters.
A broad range of interfaces, including Wiegand, Micro USB, RS-485 and RS-232, provides flexibility when connecting the module to new or existing host systems, with OSDP protocol support available as an option. Power can be supplied from 4.3V to 5.5V through Micro USB or from 9V to 30V through the X1 connector, giving designers flexibility across host systems. Firmware can also be updated after installation to support changing credentials, security requirements, or customer configurations.
An integrated SDK allows applications to run directly on the reader, reducing host-side processing for credential handling and interface logic. For local user feedback, the module features five RGB LEDs that can each be individually programmed using the on-board Intelligent Peripheral Extension (IPE), enabling more dynamic and application-specific lighting concepts. An integrated acoustic loudspeaker provides additional audible signaling for access, status and authentication events.
