DESCRIPTION

Authorization Buttons are sophisticated microelectronics sealed into miniature stainless steel

cans, creating a low cost, portable medium for storing and controlling access to sensitive

information.

Buttons are used with Button Holders as a hardware based protection system for software.

Buttons help protect the right to copy software by actually protecting the right to execute it.

Software can now be locked to a user, a machine, or an application with a complete audit

trail and guaranteed uniqueness.

The DS1420 is a Button that provides a 64-bit unique ID number, and is typically used to

uniquely identify a person or a machine.

Hardware communication with Buttons is conducted via a 1-Wire interface. The conversion

from a PC I/O port to the 1-Wire interface is the responsibility of the Button Holder.

Software applications communicate with the Button using Dallas' Access System, which

is contained in any of the Button Holder Developer's kits. The Access System provides

software developers with easy to use commands, which are embedded into the application

in order to utilize the Button resources during run time.

For more information on the Access System, please reference any of the Button Holder

data sheets.
