HF_TMUDFORD — ISO 15693 UID Emulator

Author: Tim Mudford Frequency: HF (13.56 MHz) Hardware: Generic Proxmark3

Back to Standalone Modes Index | Source Code | Development Guide

What

Reads an ISO 15693 tag UID and emulates it. Simple two-state mode: read a tag, then replay its UID to 15693 readers.

Why

ISO 15693 (iCODE, Tag-it, I-Code) tags are used in library systems, industrial automation, and access control. This mode provides a quick way to clone and emulate a 15693 tag's UID for testing readers and access systems that rely solely on UID-based identification.

How

READ: Sends an ISO 15693 inventory request. When a tag responds, captures its 8-byte UID.
EMULATE: Emulates a 15693 tag with the captured UID, responding to inventory and select commands from a reader.

LED Indicators

LED	Meaning
A+D (solid)	READ mode — waiting for tag
B+C (solid)	EMULATE mode — replaying UID
A-D (sequential blink)	Transition / activity

Button Controls

Action	Effect
Long hold (≥1000ms)	Switch between READ and EMULATE modes
Button press	Exit standalone mode (while idle)

State Machine

stateDiagram-v2
    [*] --> READ : Startup

    state READ {
        [*] --> Inventory
        Inventory --> Captured : Tag responds with UID
        Captured --> Inventory : Continue scanning
    }

    state EMULATE {
        [*] --> SimUID
        SimUID --> SimUID : Responding to readers
    }

    READ --> EMULATE : Long hold\n(UID captured)
    EMULATE --> READ : Long hold

    READ --> [*] : Button press / USB
    EMULATE --> [*] : Button press / USB
