## Intro
For more info about what is an iButton check:
{% content-ref url="/pages/Woc1ZIjcYznBGdrB4R7L" %}
[iButton](/hacktricks/todo/radio-hacking/ibutton.md)
{% endcontent-ref %}
## Design
The **blue** part of the following imageis how you would need to **put the real iButton** so the Flipper can **read it.** The **green** part is how you need to **touch the reader** with the Flipper zero to **correctly emulate an iButton**.
## Actions
### Read
In Read Mode Flipper is waiting for the iButton key to touch and is able to digest any of three types of keys: **Dallas, Cyfral, and Metakom**. Flipper will **figure out the type of the key itself**. The name of the key protocol will be displayed on the screen above the ID number.
### Add manually
It's possible to **add manually** an iButton of type: **Dallas, Cyfral, and Metakom**
### **Emulate**
It's possible to **emulate** saved iButtons (read or manually added).

If you cannot make the expected contacts of the Flipper Zero touch the reader you can **use the external GPIO:**
