RFID string values contains a strip of data that needs interpreting this way:

Raw code from the device contains 30 characters:

```
U  EM4102      2800C19D6A*F626
```

### Interpreted Data:

1. transponder_id = EM4102
2. manufaturer_id = 28
3. rfid_tag = 00C19D6A

On our custom application we can then process this data submitting the individual elements to a web-based app:

![](/images/image002.jpg)

In PHP we then have a simple test to see the result from the application:
