Warehouse Connect: RFID and IoT Smart Warehouse with Full Traceability

1. Achieve real-time, location-level inventory accuracy using RFID-based pallet tracking and QR-based product tracking.

2. Digitize all warehouse operations (receiving, put-away, picking, dispatch) through mobile apps that guide workers and capture every movement.

3. Provide a live 2D virtual warehouse showing stock position, capacity, and utilization.

4. Enable end-to-end traceability, so any product or batch can be traced from production through storage and dispatch to market.

5. Integrate with the ERP system so stock, orders, and financial records update automatically without double entry.

6. Reduce loading and dispatch time, mis-shipments, stock-outs, and expiry losses.

7. Support FEFO and batch controls, and strengthen recall readiness and audit compliance.

• RFID reliability: Metal racks, forklifts, stretch-wrapped pallets, and liquids can interfere with RF signals. We ran site surveys and tuned reader placement and antenna power to reach high read rates.

• Integration: Real-time synchronization with the ERP required careful data mapping, error handling, and reconciliation logic.

• Two-level traceability: Linking pallet-level RFID data with unit-level QR codes demanded a robust batch and hierarchy data model.

• Digitizing the layout: Every location had to be mapped accurately into the 2D virtual warehouse.

• Operations continuity: The rollout occurred in a live warehouse, using phased go-lives so dispatch was never interrupted.

• Connectivity: Mobile workflows needed to tolerate weak Wi-Fi zones.

• Adoption: Workers moved from paper to handhelds, which required hands-on training and simple, task-guided interfaces.

Warehouse Connect is an IoT-enabled warehouse management system that uses RFID pallet tracking, QR-based product identification, and mobile apps to give complete, real-time control over inventory, warehouse operations, and product traceability.

The challenge. Warehouse operations relied heavily on manual records, delayed ERP updates, and operator memory. Pallets were misplaced, stock counts needed time-consuming physical verification, dispatches were error-prone, and tracing a product after it left the warehouse was slow and unreliable. This created risk for service levels, working capital, and product recalls.

The solution. We built an integrated platform with four layers:

1. Identification layer. Every pallet receives a UHF RFID tag, and cartons/products carry QR codes. RFID readers at dock doors and on handling equipment capture pallet movements automatically, while QR scanning supports unit-level accuracy.

2. Operations layer (mobile apps). Workers use mobile apps for goods receipt, guided put-away, picking, and dispatch. The app directs them to the right location, validates each action against the order, and records it instantly.

3. Visibility layer. A 2D virtual warehouse inside the system shows every rack, bay, and pallet in real time, with capacity, utilization, aging, and expiry status. Managers can locate any pallet in seconds.

4. Integration and traceability layer. The WMS is integrated with the ERP, so receipts, stock levels, orders, and dispatches stay synchronized without re-keying. Batch and serial data link each pallet and product to its production, storage, and dispatch history. Through the mobile app, a product found in the market can be scanned and traced back to its batch and journey, which supports quality control and recall handling.

How it works day to day. Goods arrive and are tagged; the system assigns storage locations; RFID gates confirm movement; the 2D warehouse updates; orders from the ERP generate pick and dispatch tasks; vehicles are loaded with RFID verification that the right pallets are on the right truck; and the ERP is updated automatically. Exceptions such as wrong pallet, expired stock, or location mismatch trigger immediate alerts.

Delivery approach. We mapped existing processes, designed the RFID layout and location structure, built and tested the apps, then piloted in one warehouse before scaling. Training and phased go-live ensured the teams adopted the system without interrupting dispatch operations.

Outcome in brief. The company now operates with accurate real-time stock, faster and more reliable dispatch, and the ability to trace any product end to end.

The system is deployed at warehouse Connect in Faisalabad/ Punjab, Pakistan and birmingham, United Kingdom, covering 3 warehouses and distribution points, and tracking product flow to markets across country. It was designed and built by Invictus Solutions in Faisalabad. The platform is multi-warehouse by design, so additional sites can be added centrally, and it is suitable for rollout across other industries, including FMCG, pharmaceuticals, textiles, and distribution, and in other emerging markets.
