Ibutton | RFID Tag

Description

iButton® devices are small, durably packaged modules with globally unique digital addresses. An iButton device uses a stainless steel 'can' as an electronic communications interface. The iButton can has a data contact, called the 'lid', and a ground contact, called the 'base'. Each of the iButton contacts is connected to the silicon chip inside. The iButton base includes a flange to simplify attaching the iButton device to just about anything.
