Reading a tag...
On the Flipper Zero, select `125 kHz RFID`, `Read`. Place the tag against the back of the Flipper (or use another Flipper that is emulating the tag) and you should see the latitude and longitude displayed on the screen.
## Protocol format
- 125kHz, FSK2a, RF/50, FC/8, FC/10
- Preamble: 0xF337
- Data: 8 bytes (first 4 bytes are latitude, last 4 bytes are longitude)
- Checksum: XOR of the 8 bytes of data
NOTE: The 4-bytes are just float values that are cast to a 4-byte integer.
