 **High-frequency 13.56 MHz tags are a set of standards and protocols**. They are usually referred to as [NFC](https://nfc-forum.org/what-is-nfc/about-the-technology/), but that's not always correct. The basic protocol set used on the physical and logical levels is ISO 14443. High-level protocols, as well as alternative standards (like ISO 19092), are based upon it. Many people refer to this technology as **Near Field Communication (NFC)**, a term for devices operating over the 13.56 MHz frequency.

 To put it simply, NFC's architecture works like this: the transmission protocol is chosen by the company making the cards and implemented based on the low-level ISO 14443. For example, NXP invented its own high-level transmission protocol called Mifare. But on the lower level, Mifare cards are based on ISO 14443-A standard.

 As the **decoding of the infrared** signal happens on the **software** side, Flipper Zero potentially supports the **reception and transmission of any IR remote codes**. In the case of **unknown** protocols which could not be recognized - it **records and plays back** the raw signal exactly as received.

+### Universal Remotes
+
+Flipper Zero can be used as a **universal remote to control any TV, air conditioner, or media center**. In this mode, Flipper **bruteforces** all **known codes** of all supported manufacturers **according to the dictionary from the SD card**. You don't need to choose a particular remote to turn of a restaurant TV.
+
+It is enough to press the power button in the Universal Remote mode, and Flipper will **sequentially send "Power Off"** commands of all the TVs it knows: Sony, Samsung, Panasonic... and so on. When the TV receives its signal, it will react and turn off.
+
+Such brute-force takes time. The larger the dictionary, the longer it will take to finish. It is impossible to find out which signal exactly the TV recognized since there is no feedback from the TV.
+
+### Learn New Remote
+
+It's possible to **capture an infrared signal** with Flipper Zero. If it **finds the signal in the database** Flipper will automatically **know which device this is** and will let you interact with it.\
+If it doesn't, Flipper can **store** the **signal** and will allow you to **replay it**.
