GAO’s Cloud-based Automated Medication Verification (AMV) Systems
GAO’s Cloud-based Automated Medication Verification (AMV) Systems deliver a resilient cloud-first medication checking platform engineered to enhance drug authentication, bedside verification, and pharmacy-to-ward traceability. This cloud-enabled medication validation solution employs IoT wireless technologies such as BLE, RFID, Zigbee, Wi-Fi HaLow, or UWB to capture real-time medication identifiers, workflow timestamps, and chain-of-custody records. The cloud architecture offers high-availability clusters, distributed data lakes, and auto-scaling microservices that allow hospitals, clinics, and research centers to synchronize medication data securely across multiple facilities. Healthcare teams benefit from unified dashboards, remote administration, and robust interoperability with EHR, pharmacy management software, asset tracking systems, and clinical analytics. With engineering offices in New York City and Toronto, GAO has supported North American healthcare organizations for more than four decades with R&D-driven cloud platforms and stringent QA processes.
GAO’s Cloud Architecture for AMV Systems
IoT Device Interaction Layer
- BLE medication tags, RFID smart labels, Zigbee nodes, Wi-Fi HaLow readers, and UWB anchors interface with medication carts, pharmacy benches, infusion pumps, and medication cabinets.
- Edge adapters capture unique identifiers, timestamp metadata, user credentials, and procedural context.
Edge Gateway Layer
- Secure gateway appliances deployed in pharmacy cleanrooms, ICU medication stations, or ward corridors normalize the data, apply protocol translation, and encrypt transmissions.
- Gateways buffer records during connectivity disruptions and sync to the cloud when uplink channels stabilize.
Cloud Connectivity and API Gateway Layer
- TLS-enforced REST and MQTT endpoints provide data ingress.
- API load balancers distribute requests across containerized microservices responsible for medication lookup, clinician authorization checks, and alert generation.
Distributed Processing & Microservices Layer
- Stateless medication verification engines execute drug-order matching, formulary validation, and exception handling.
- Stream processors support real-time event detection for missing doses, expired medications, or unauthorized handling.
Data Lake & Storage Layer
- Immutable audit logs, time-series telemetry, and medication lifecycle histories are stored in multi-region cloud data lakes.
- Archive buckets retain long-term compliance logs aligned with healthcare regulations.
User Interface & Analytics Layer
- Web dashboards allow clinicians, pharmacists, and supervisors to monitor medication flows, verify transactions, and run compliance analytics.
- Administrators configure access privileges, workflow parameters, and policy rules through browser-based consoles.

High accuracy for automated scanning, ideal for cabinets, carts, and boxed medication inventories. - Zigbee
Mesh networking for dense pharmacy environments and multi-room monitoring. - Wi-Fi HaLow
Long-range, low-power connectivity well-suited for large hospital campuses. - UWB
High-precision location tracking for controlled substances or critical dosages requiring exact traceability.
Local Server Version of GAO’s AMV System
GAO also offers a local-server deployment variant for facilities requiring on-premise hosting behind restricted firewalls. This configuration uses the same BLE, RFID, Zigbee, Wi-Fi HaLow, or UWB device ecosystem but routes all verification logic, database operations, and dashboards through an internal data center. The on-premise model fits customers with strict data-sovereignty mandates or air-gapped clinical environments while still benefiting from our remote or onsite technical support teams in the U.S. and Canada.
