DS9104

Digital Decoder Ring


Please check latest availability status for a specific part variant.

Description

The DS9104 Digital Decoder Ring is a portable database disguised as jewelry with the DS1996 Memory iButton® as signet. Data is transferred serially using the 1-Wire® protocol through a simple interface. Data is first written to a scratchpad, verified, and then transferred to NV memory. The 64-bit serial number guarantees that each ring is unique and traceable. The ring communicates by touch through a parallel or serial port interface. Applications include access control to buildings, doors, and computers and digitized storage of personal information.

Note: Rings cannot be resized as the iButton will not withstand the high temperatures required.
