Read and Write Hitag2

With Proxmark3, you can read and write Hitag2 tags. To read a Hitag2 tag, follow these steps:

Connect your Proxmark3 device to your computer and ensure it is recognized.
Open a terminal and navigate to the Proxmark3 client directory.
Start the Proxmark3 client by running the following command:
```
./pm3
```
Once the client is running, place the Hitag2 tag near the Proxmark3 antenna.
In the Proxmark3 client, enter the following command to read the Hitag2 tag:
```
lf hitag read --ht2 -k BDF5E846
```

BDF5E846 is usually a default key for Hitag2 tags. If the tag uses a different key, replace it with the correct one.

Take a note of the output, specifically the hexadecimal representation of the tag’s data for page 4-7 listed in the output table. The first column of the table shows the page numbers. This data will be used for writing back to the new tag.

Finaly place the new Hitag2 tag near the Proxmark3 antenna and enter the following command to write the data to the new tag:

lf hitag wrbl --ht2 -k bdf5e846 -p 4 -d [PAGE 4 HEX DATA]
lf hitag wrbl --ht2 -k bdf5e846 -p 5 -d [PAGE 5 HEX DATA]
lf hitag wrbl --ht2 -k bdf5e846 -p 6 -d [PAGE 6 HEX DATA]
lf hitag wrbl --ht2 -k bdf5e846 -p 7 -d [PAGE 7 HEX DATA]
