Note: Infrared signals require a direct line of sight to function. The signal cannot pass through walls or solid objects. You need to point your Flipper Zero directly at the device's IR receiver, just like you would with a standard remote.

This physical requirement is the main constraint, but for in-room control, the Flipper Zero is an exceptionally capable tool.

2. Access Control System Analysis

Your Flipper Zero opens up the invisible world of radio-frequency identification (RFID) and near-field communication (NFC). You can use it to read, save, and emulate various types of access cards and tags, giving you a deeper understanding of the systems you interact with daily.

Reading RFID and NFC

The device comes equipped with antennas to interact with both low-frequency (125kHz) and high-frequency (13.56MHz) tags. This allows you to read a wide array of protocols. For high-frequency NFC, it supports standards like:

• MIFARE Classic 1K
• MIFARE Classic 4K
• MIFARE Classic Mini

It also has an extensive library for common low-frequency 125kHz cards, including HID Prox, EM4100, and Indala.

Beyond access cards, you can explore fun applications like interacting with video game collectibles. For example, you can read and back up your Nintendo Amiibos. If a normal read fails, you can try a special workaround:

In the NFC menu, navigate to Extra Actions > Unlock NTAG/Ultralight > Auth as Ameebo and then scan your figure. This often allows you to successfully save the Amiibo data to your Flipper.

Emulating Access Cards

Once you save a compatible card's data, your Flipper Zero can emulate it. This means the Flipper can pretend to be that card. This is one of the most powerful flipper zero uses for convenience. You can create a digital backup of your personal gym pass or office key card, allowing you to leave the physical cards at home. This feature is also excellent for pentesters who need to analyze and test the security of an access control system.
