Setup, Compatibility & Care
To begin using the iButton Dallas keys, ensure your hardware system is configured to read the unique ID string of the iButton protocol. Simply register each individual fob's serial number within your point-of-sale software's security management interface. No external batteries are required as the key is powered by the reader upon contact. To maintain the integrity of the contact surface, periodically wipe the metal face of the fob with a clean, dry cloth to remove any buildup of skin oils or residue. Avoid using abrasive chemicals or metal scrubbers that could scratch the contact point, as this may lead to intermittent read errors.
