ibutton Access
The iButton is a computer chip enclosed in a 16mm thick stainless steel can. This system can store passwords up to 64 digits with encryption capability. Because of this unique and durable container, up-to-date information can travel with a person or object anywhere they go. The steel i Button can be mounted virtually anywhere because it is rugged enough to withstand harsh environments, indoors or outdoors. It is small and portable enough to attach to a key fob, ring, watch, or other personal items, and be used daily for applications such as access control to buildings and computers, asset management, and various data logging tasks. iButtons are memory buttons Therefore, the concept of a mobile memory chip that communicates by touch remains fundamental to all iButtons.Memory iButtons come in these different types to allow you to pick the right device for your specific application.

All memory iButtons have these characteristics

  • Unique and unalterable factory-lasered address
  • Low-cost, low-power 1-WireŽ interface
  • Ability to operate as mobile database, in either standalone or networked application designs


  • i Button Applications: The iButton is ideal for any application where information needs to travel with a person or object. Affixed to a key fob, watch, or ring, an iButton can grant its owner access to a building, a PC, a piece of equipment, or a vehicle. Attached to a work tote, it can measure a variety of processes to improve efficiency, such as manufacturing, delivery, and maintenance. Some versions of the iButton can be used to store cash for small transactions, such as transit systems, parking meters, and vending machines. The iButton can also be used as an electronic asset tag to store information needed to keep track of valuable capital equipment.

    iButton Durability: The silicon chip within the iButton is protected by the ultimate durable material: stainless steel. You can drop it, step on it, or scratch it. (Try any of those with your Smart Card and see what happens.) The iButton is wear-tested for 10-year durability.
