Digitized warehouse logistics: More efficient, transparent and secure thanks to new technologies

Technology boost for warehouse processes with RFID & GS1: Leveraging the advantages of digitalization

The digitalization of warehouse logistics is a key component of modern supply chain strategies. Technologies such as RFID (Radio Frequency Identification) and the GS1 DataMatrix code play a crucial role in this. Their combination significantly increases efficiency, transparency, and process reliability. Both technologies offer specific advantages that complement each other perfectly, thereby unlocking new potential for companies.

1. Fundamentals of the technologies

RFID technology

RFID uses radio waves to wirelessly transmit data and uniquely identify objects. An RFID system consists of three main components:

RFID tag: A microchip with a unique identifier that is attached to products or pallets.
RFID reader: A scanner that can read the information from the tag without requiring line of sight.
Database and software: A system for processing the collected data in real time.

Advantages of RFID

Contactless reading: Readers can read multiple tags simultaneously, even without a direct line of sight.
Automation: Manual scans are eliminated, thus accelerating work processes.
Robustness: RFID tags are resistant to external influences such as dirt or moisture.

GS1 DataMatrix Code

The GS1 DataMatrix code is a two-dimensional barcode that stores information in a compact, machine-readable format. It can contain various data elements such as:

GTIN (Global Trade Item Number),
Serial numbers,
Batch numbers,
Includes expiration dates and more.

Advantages of the GS1 DataMatrix code

High information density: It can store more data in a smaller area than conventional barcodes.
Error tolerance: Even damaged or partially obscured codes can often still be read.
Cost-effective implementation: Most scanners can capture GS1 DataMatrix codes without requiring expensive hardware upgrades.

2. Combined use of RFID and GS1 DataMatrix

Unique identification and traceability

The combination of RFID and GS1 DataMatrix enables precise identification and seamless traceability of products throughout the entire supply chain:

The GS1 DataMatrix code stores detailed product information that enables targeted identification.
RFID complements this with wireless detection without line of sight, which is particularly advantageous in automated warehouse processes.
Together, they enable rapid product localization during recalls or quality controls.

Process optimization in warehouse logistics

The synergy of both technologies leads to a significant improvement in process efficiency:

Faster goods receipt and dispatch: RFID enables the simultaneous recording of multiple products, while the GS1 DataMatrix provides additional details.
Error minimization: Automated data capture reduces human errors, such as those encountered during manual scanning.
Improved inventory control: Stock levels can be updated in real time, as RFID can report the position of a product, while the GS1 DataMatrix provides further data such as the expiration date.

Integration into existing systems

Since both technologies are based on the global GS1 standards, they can be seamlessly integrated into existing ERP and WMS (Warehouse Management Systems). For example, a warehouse management system can be programmed to automatically link RFID-scanned goods with GS1 DataMatrix data, thereby providing comprehensive product information.

Optimization of inventory management

The combination of RFID and GS1 DataMatrix enables more efficient inventory management:

Automatic inventory update: RFID records the movement of goods in the warehouse, while the GS1 DataMatrix provides additional product attributes such as expiration dates.
Real-time tracking: RFID can enable the location tracking of pallets or cartons in large warehouses, which significantly speeds up the search for specific products.

Suitable for:

Sensor technology and measurement technology: How will the GS1 DataMatrix Code change the sensor technology industry?

3. Practical Use Cases

Goods receipt and goods issue

RFID enables the rapid recording of goods movements during entry and exit.
The GS1 DataMatrix code provides detailed information for quality control or specific customer requirements.
This combination allows storage times to be reduced and error rates to be minimized.

Inventory management

RFID monitors inventory levels in real time and provides information about location changes.
The GS1 DataMatrix stores additional data that can be used for inventories and audits.
Companies can optimize their inventory strategy by applying FIFO and LIFO methods more effectively.

Traceability and quality assurance

In the case of product recalls or quality checks, RFID and GS1 DataMatrix enable the unambiguous identification of affected products.
RFID supports rapid localization within the warehouse.
The GS1 DataMatrix code provides detailed origin and batch data to ensure accurate traceability.

Sustainability and cost savings

Automated processes reduce paper consumption and minimize manual labor.
Precise inventory control allows companies to optimize storage capacities and avoid unnecessary overproduction.
Better tracking of expiration dates reduces food and medicine waste.

4. Advantages of combined use

The combination of both technologies creates numerous advantages for companies:

Time saving

RFID enables fast and contactless data collection.
The GS1 DataMatrix provides targeted detailed information for specific audits.

Increased accuracy and error reduction

RFID eliminates the risk of manual scanning errors.
The GS1 DataMatrix code ensures that all important product information is available at all times.

Transparency and security

Complete traceability in the supply chain.
Faster identification of problematic batches or products.

Scalability and future security

Both technologies can be flexibly adapted to company growth and new market requirements.
They support the implementation of further digital systems such as IoT-based warehouse monitoring.

5. Efficient warehouse logistics: Ahead with RFID and GS1 technology

By integrating RFID and the GS1 DataMatrix code, companies can significantly improve their warehouse logistics. While RFID enables the rapid and automated tracking of large quantities of goods, the GS1 DataMatrix code provides detailed information about individual products. The combination of these technologies leads to greater efficiency, reduced error rates, improved traceability, and sustainable cost savings.

Forward-thinking companies looking to digitize their processes should leverage the synergy of RFID and GS1 DataMatrix. This not only creates competitive advantages but also ensures that logistics processes are efficient, error-free, and sustainable.
