Multi-Tag Identification Devices, Variable-Power Standoff Readers For Same, and Related Systems

Systems, apparatuses, methods, and software for monitoring compliance of sanitizees (e.g., health care workers, food service workers, sanitization/janitorial workers etc.) with sanitization protocols to be followed for encounters with sanitization-protocol targets (e.g., patients, food-preparation areas, health care facilities/appurtenances, restrooms, etc.). In one example, a system includes sanitization verification systems located close to the targets and mobile node devices issued to the sanitizees. Each verification system can be configured to test the efficacy of sanitization procedures performed by the sanitizees prior to encountering a target, to provide authorizations, via the node devices, to the sanitizees to proceed with target encounters, and to open monitoring sessions during which the node devices record information concerning interactions with the targets. The node devices are configured to annunciate sanitization statuses of the sanitizees throughout a work period as the sanitizees continually interact with verification stations and encounter targets.
