HF_LEGIC — Legic Prime Read/Simulate

Author: uhei Frequency: HF (13.56 MHz) Hardware: Generic Proxmark3

Back to Standalone Modes Index | Source Code | Development Guide

What

Reads Legic Prime tags and simulates them. Auto-detects card type (MIM256, MIM512, MIM1024).

Why

Legic Prime is a proprietary HF contactless technology used in European access control, time & attendance, and vending systems. This mode provides standalone read-and-replay capability.

How

  1. Search: Continuously scans for Legic Prime tags
  2. Read: On detection, dumps the tag memory (auto-detects size)
  3. Simulate: Broadcasts the captured tag data
