An iButton is a microcircuit, encapsulated in
a stainless steel weather resistant button, of great durability and
reliability (1,000,000 recordings per button). Each iButton is a
guaranteed, unique, never to be repeated, factory programmed ROM.
Its 16 character serial number is kept in laser-cut polysilicon
links
!not as stored
magnetic charge!.
Because of its design and the strict control of the manufacturing
process, the DS1990A iButton is an identifier that cannot be
counterfeited. It is appropriate for applications where absolute
identification is required. Due to its great reliability, the
iButton developed and manufactured by DALLAS SEMICONDUCTOR has
positioned itself solidly in the international market as a universal
identifier of Persons, Objects and Events. iButton dimensions are
