Logistics and supply chain management businesses are highly competitive and unpredictable due to broad global market factors. For businesses, the ability to answer critical questions—such as Where is the consignment? Which vehicle is carrying it? How much inventory is in the warehouse? What is the condition of goods in transit? - defines operational efficiency and customer satisfaction. Traditional manual methods relied on paperwork, phone calls, and visual inspections, which were prone to delays, human error, and guesswork.
Using technologies like RFID, barcoding, IoT, BLE, UWB, GPS, etc., facilitates a quick and accurate tracking of assets, consignments, fleets, etc., with square meter precision and ease.
RFID offers a cost-effective, measured, and precise asset tracking solution that can be easily integrated with existing solutions and software infrastructure used by supply chain managers. RFID-based solutions are developed today to not only keep track of all the assets, consignments, inbound and outbound logistics, but also present a clear picture of inventory in real-time. It highlights bottlenecks, inventory shortcomings, and ensures data-driven decision-making.
When Manual Tracking, Guesswork, and Delays Were the Norm
Before the adoption of advanced tracking technologies like RFID and IoT, supply chain managers faced challenges such as:
1.Manual log entries leading to inaccurate inventory counts.
2. Delayed updates on consignment location and delivery status.
3. Inability to detect pilferage, loss, or misplacement of goods in real time.
4. Bottlenecks in order fulfillment and warehouse operations due to poor visibility.
These inefficiencies often translate into increased costs, reduced trust between partners, and dissatisfied customers.
Barcode technology has been used in retail since the early 1970s, but it was limited to product identification and POS. The introduction of barcoding systems in supply chains improved supply chain operations by enabling faster and more accurate identification of goods. With handheld scanners and barcode labels, businesses could manage inventory better, reduce manual errors, and simplify warehouse operations. However, barcoding had limitations:
1. Line-of-sight scanning was required.
2. Data capture was time-consuming for large inventories.
3. Barcodes were easily damaged, reducing readability.
While barcodes were a step forward, the need for automated, contactless, and real-time asset tracking pushed industries to explore better solutions.
The Invention of EPC and Low-Cost RFID Tags
In the early 2000s, the development of the Electronic Product Code (EPC) standard and the mass production of low-cost RFID tags transformed supply chain management and asset tracking into a scalable and cost-effective solution. Unlike barcodes, RFID tags:
1.Do not require line-of-sight scanning.
2. Can be read in bulk and at high speed.
3. They are durable, withstanding harsh environmental conditions.
4. Can carry dynamic data such as batch number, expiry date, or location.
It is worth noting that the cost of RFID tags has come down significantly due to massive adoption led by the retail and healthcare sectors and standardized RFID communication protocols by EPCglobal and ISO. Earlier, an RFID label cost around INR40-50, which has now come down to INR4-5 only. Similarly, the cost of RFID systems, including hardware like RFID readers, antennas, and printers as well as RFID software, has also come down, boosting RFID adoption across market verticals.
These advantages made RFID an attractive choice for supply chain automation, warehouse management systems (WMS), and order fulfillment workflows. Multi-national businesses like Walmart, P&G, GS1, etc. supported the development of EPC and global RFID standards with EPCglobal and ISO. Walmart, as an early adopter of RFID, started pilot projects in its retail stores, essentially promoting the technology.
RFID Asset Tracking Solutions: Bringing Accuracy and Efficiency
RFID solutions today deliver real-time visibility of assets across warehouses, vehicles, and distribution centers. With the integration of IoT sensors, BLE (Bluetooth Low Energy), UWB (Ultra-Wideband), and GPS technologies, logistics businesses can track goods with square-meter precision and even monitor temperature, humidity, or shock levels for sensitive cargo.
Key benefits of RFID asset tracking in supply chain and logistics include:
1. Real-time asset visibility, where you get instant updates on consignment, fleet, or equipment location.
2. Faster order fulfilment via automated scanning and bulk identification, reducing processing times.
3. Inventory accuracy with minimized stock discrepancies and improved warehouse efficiency.
4. Condition monitoring where RFID and IoT sensors track environmental parameters, ensuring goods arrive in perfect condition.
5. Reduced loss and theft with real-time alerts when assets move unexpectedly or outside authorized zones.
6. Seamless integration as an RFID asset tracking solution offers compatibility with ERP, WMS, and Transportation Management Systems (TMS).
From Visibility to Predictive Supply Chains
The future of RFID-enabled supply chains lies in predictive analytics. With RFID, IoT, and AI-driven platforms, businesses can not only know the real-time location of assets but also predict delays, optimize routes, and automate replenishment.
In simple words, this transition, from reactive tracking to predictive supply chain management, is where RFID creates long-term strategic value for businesses. RFID offers a streamlined, automated way to capture accurate data at each junction, and modern technologies like AI and ML facilitate data-driven decision-making.
To summarize, RFID technology has shifted supply chain and logistics management from a world of manual tracking, guesswork, and delays to one of real-time visibility, accuracy, and efficiency. RFID labels on goods, vehicles, and machinery can reduce manual intervention and automate workflows, helping logistics companies cut operational costs, enhance productivity, and build trust with customers.
