YiToo delivers end-to-end access control across hardware, platform, and cloud. We unify identity and permissions for doors, turnstiles, elevators, and parking with multimodal authentication (face, fingerprint, card, QR, NFC, Bluetooth). Our edge-cloud design keeps sites running offline, while open APIs/SDKs speed integration. From offices and campuses to factories, hospitals, and residential complexes, YiToo raises security standards, streamlines operations, and improves user experience.
