RDR NFC Event Recorder

---

The RDR NFC Reader is a compact, wireless sensor for use in Parametric's RET system, which is used for rail and infrastructure optimization.

It enables easy recording and time stamping of manual actions—without integration, cabling, or external infrastructure.

How it works

The reader is installed in vehicles, on infrastructure facilities, or in depots. By reading NFC tags, manual processes or events can be recorded with a precise time stamp. This data is automatically transmitted via LoRaWAN to the RET analysis software, where it is used to validate and track measures.

This allows operators to track whether, when, and how a specific measure was carried out and what impact it had on system behavior – without any integration into existing systems.

Typical applications

• Chassis replacement
• Wheel regrinding
• Lubrication processes
• Fault detection while driving
• Vehicle in depot or service

Advanced functions

The RDR NFC Reader offers optional digital inputs and outputs:

• Inputs for connecting external buttons or sensor signals
• Outputs that can be controlled via LoRaWAN downlinks (e.g., for alarm lights or acoustic signal transmitters)

Note: An external power supply is required to operate the digital I/Os.
