An iButton is made up of a tiny computer chip enclosed inside a small steel can. There are over 20 different types of iButtons, each with its own unique function and product specification. The iButton stainless steel case provides unparalleled durability.
Portability and durability are two reasons why iButton products are very popular. Depending on your application, you will need some hardware to help you communicate with, mount, and carry your iButton device.
