Protocol support, tag capacity and reader mode differ by model and firmware. Check the product page before ordering; “NFC emulator” does not mean every NFC or RFID protocol is supported.

Chameleon portable emulators

Chameleon Ultra

A portable open-source LF/HF RFID tool for reading, emulation and authorized security research. It is the most complete choice in the Chameleon family when both 125 kHz and 13.56 MHz workflows are required.

Chameleon Lite and Chameleon Mini

Choose these for smaller, focused 13.56 MHz / MIFARE emulation workflows where the full dual-frequency feature set of Chameleon Ultra is not required.

NFC emulators and development tools

PN532Killer

A multi-function reader, emulator and sniffer for ISO14443A, ISO14443B, ISO15693 and EM4100 research workflows.

Pixl.js OLED for Amiibo

A display-equipped NFC device designed for managing compatible virtual tag collections and Amiibo workflows.

GroveNFC

An open communication NFC module for M5Stick, AtomS3, CardPuter and other Grove-compatible hosts. It supports reader and emulator development with open-source demo firmware.

M5Stack NFC Universal Unit (ST25R3916)

An I2C NFC reader/writer and development unit supporting ISO14443A/B, FeliCa and ISO15693, plus NFC-A and NFC-F card emulation modes.

Multi-purpose device

Flipper Zero

A portable multi-tool that includes NFC and LF RFID functions alongside other radio and hardware interfaces. Choose it for broader experimentation rather than a dedicated NFC-only workflow.
