In this video we learn how to use a ProxMark3 (PM3) to analyze a low-frequency (125kHz) RFID fob that is using Manchester encoding. We read an EM4100 tag, clone it to a T5577, and we simulate the tag using the PM3. We validate all of these operations using our Flipper Zero! We use the PM3 to look at the T55xx data and we read, plot and analyze signals. At the end of the video, we analyze at a blank InstaFob and determine the modulation and the block 1 data that can be used to identify blank InstaFobs!

In future videos we will use the information from the video to create custom encoders and decoders for our Flipper Zero, enabling our Flipper Zero to detect an InstaFob and to wipe a fob (or any T5577) back to the original blank InstaFob signature.
