# Obtaining Terminal ID with Raspberry PI Pico

How to Obtain Terminal ID with Raspberry Pi Pico

```python
import machine
import binascii

device_id = binascii.hexlify(machine.unique_id()).decode()

print(device_id)
```

### Result
```
d66a64xxxxxxxxxx
```

You can achieve this by using `machine.unique_id()`.

The result can be obtained as binary data, which might be difficult to use as it is. Therefore, it is a good idea to convert it to a string using either `binascii` or `base64`.

`binascii` comes standard with MicroPython.

# Additional Information

```python
>>> machine.unique_id()
b'\xe6axxxxxxxx'

>>> binascii.hexlify(machine.unique_id())
b'e66164xxxxxxxxxx'

>>> binascii.hexlify(machine.unique_id()).decode()
'e66164xxxxxxxxxx'
```
