In this video we learn how the Flipper Zero is able to decode and emulate low-frequency (125kHz) RFID signals and how it can write data to a T5577 tag. We walk through all of the code, understanding the role of each method. We then make a new protocol "Demo1" that will program a T5577 tag with custom hard-coded data.

In future videos we will use the information from the video to create custom encoders and decoders, enabling our Flipper Zero to support our additional protocols.
