iButton is a little memory device that looks like a watch battery. It
allows you to write/read small amounts of data to/from it. It can be
used in many applications but it is most commonly used in security
devices, such as secured entry.
These iButton devices usually come with plastic holders that you can
attach to a key chain. Then, you can program it with a serial code
number, etc. Then, you press the device up to the iButton
connector. The data is sent down to the controlling device (ie -
Basic Stamp) and the controlling device responds accordingly (ie -
unlocks a door).
