The DS1990A-F5+ provides a guaranteed unique ID in a small iButton® form. This iButton can be used as a key in access control systems, inventory control applications, work-in-progress tracking, or other applications that require a low-cost, reliable method of validating identification.

There are many creative uses for this iButton and some that we have seen include:

  • A key in a nursing home with many door connected with a single 1-Wire bus using our LinkLocator product to identify the door being accessed,
  • To start carnival games so that user IDs may be tracked back to cash boxes, eliminating theft
  • A key for our own data center
  • Guard tour devices mounted on walls or other locations using the DS9093S button mount.
