PassiveBolt is a decentralized identity platform that uses blockchain technology and cryptographic attestations for access control to physical spaces. The platform operates on Web3 principles with a blockchain registry for universally unique identifiers, enabling access control through identity wallets rather than traditional credentials like cards or PIN codes. The system provides hardware components including Web3-capable locks, readers, and control panels that support both cryptographic and traditional credentials. The platform features modular connectivity designs supporting multiple protocols for lock and access control systems. The mechatronic technology uses gearless direct actuation for energy efficiency and compact design. PassiveBolt offers solutions for hospitality and car rental industries, automating check-in processes and mobile key delivery. The platform includes decentralized applications (dApps) and decentralized web apps (DWA) for managing access control. The system incorporates proprietary sensors with algorithms for door tracking, micro location, and touch detection. The platform is available across web, iOS, and Android platforms with API access and documentation. PassiveBolt operates as a Tier1 supplier, providing enabling technologies for industry partners to deploy access control solutions.
