RFID Software

Software Tips

RFID is a key technology for companies that want to capture inventory, goods, operating resources, or individual objects faster and more accurately. The radio technology enables automatic identification without direct line of sight, thereby creating the basis for more efficient processes, better transparency, and higher data quality in warehousing, production, retail, and many other areas. RFID is not just a topic for large corporations: Mid-sized companies also use the technology when goods movements, traceability, or inventory processes are to be made more economical.

What is RFID?

RFID stands for Radio Frequency Identification. It refers to a wireless technology that allows information to be exchanged via radio between an RFID tag and a reader. A typical RFID system consists of transponders or tags, readers, antennas, and a software layer that processes the captured data and integrates it into business processes. Unlike barcodes, direct line of sight is not required in every case. This makes it possible to identify objects even when they are inside boxes, on pallets, in containers, or within ongoing processes.

In day-to-day business, RFID is particularly interesting when many objects need to be captured automatically with as little manual effort as possible. The technology helps make the movements and statuses of products, load carriers, tools, or operating resources digitally visible. Standards such as EPCIS also ensure that simple read data is turned into business-relevant events, i.e. information about what was captured, where, when, why, and in what condition.

What types of RFID are there?

A basic distinction is made between passive, active, and in some cases battery-assisted RFID tags. Passive tags draw their energy from the field of the reader. They are cost-effective and therefore especially suitable for large volumes. Active tags have their own power supply and achieve significantly greater ranges. GS1 points out that active tags can enable ranges of 100 meters or more, while passive tags cover shorter distances depending on frequency, environment, and tag design. In practice, HF and UHF in particular play an important role; passive UHF tags, i.e. RAIN RFID, are especially widely used.

What advantages does RFID offer companies?

• Automated data capture: RFID enables the automatic identification of objects without direct line of sight. In many cases, multiple tags can be captured simultaneously. This saves time, reduces manual steps, and minimizes capture errors.
• High efficiency for large volumes: RFID delivers noticeable efficiency gains, especially in processes involving high volumes of goods, many movements, or regular inventory reconciliation.
• Faster and easier capture: RAIN RFID allows the rapid capture of many items without requiring each individual object to be specifically scanned.
• Greater inventory and process transparency: Companies can see more quickly where goods, containers, or operating resources are located and whether processes are running as planned.
• Better traceability: Standards such as EPCIS help represent physical events consistently along the supply chain or within operations. This improves the traceability of goods movements and process steps.
• Basis for quality assurance and analytics: RFID data supports quality assurance, real-time analytics, and well-founded operational decisions.
• Scalability: RFID can first be introduced in a small application area, such as inventory counting or asset tracking, and later expanded to additional sites, warehouse areas, or processes.
• Future readiness: The technology is established in many industries and is being used increasingly often. This shows that RFID is no longer just a niche solution.

How do companies find the right RFID software?

RFID software is the link between physical data capture and operational use. It determines whether read data actually becomes usable information and stable processes. Therefore, the selection should not be based only on feature lists, but on the specific benefit for your own workflows.

1. Define processes and goals first

The starting point should always be the question of which problem is to be solved. Is it about inventory counting, inventory accuracy, goods tracking, traceability, tool management, or access control? Only when it is clear which business processes are to be supported can it be assessed which software functions are actually needed. Clearly defined target metrics such as time savings, inventory quality, error reduction, or process reliability are especially important here.

2. Pay attention to system integration

An RFID solution only unfolds its full benefit when it is integrated into existing systems. Interfaces to ERP, WMS, MES, shop floor, or BI systems are therefore important. In practice, the software should prepare RFID events in such a way that they can be translated into business logic and processed automatically. Standards such as EPCIS show how such event data can be structured.

3. Check middleware and data filtering

A key selection criterion is how well the software filters, consolidates, and cleans large volumes of raw RFID data. This is often exactly where it is decided whether a project runs stably or whether unnecessary volumes of data overload downstream systems. The GS1 ALE standard describes precisely this task: applications should receive filtered and consolidated data capture information, not unstructured raw signals. For companies, this is a particularly important quality feature.

4. Ensure hardware compatibility and standards support

The software should support as many different readers, antennas, and mobile devices as possible or at least clearly document which manufacturers and protocols it works with. Support for open standards is equally important. In the RFID environment, GS1/EPC RFID standards are relevant, among others, for air interface, reader management, ALE, and EPCIS. This reduces the risk of unnecessary vendor lock-in and improves future readiness.

5. Evaluate scalability and operational capability

Good RFID software should not only work in a pilot, but also remain stable in day-to-day operation across multiple areas or locations. This includes multi-client capability, user and authorization concepts, monitoring, logging, alerts, and robust device management. In the GS1 environment, reader management is explicitly described as an interface for status and health information from readers. This is particularly important when a company wants to operate many reading points on a permanent basis.

6. Consider security and data protection as part of the evaluation

RFID software should support roles, authorizations, logging, and, where appropriate, protection mechanisms against unauthorized access. Especially in personal-data-related applications, healthcare, or security-critical environments, functional suitability alone is not enough. Data protection and security must be part of the selection process, not something addressed only after go-live.

7. Carry out a proof of concept under real conditions

Before making a final decision, there should always be a practical test under real-world conditions. This applies especially in environments with metal, liquids, densely packed goods, conveyor technology, or multiple simultaneous reading points. A proof of concept shows whether read rates, process logic, data quality, and integration actually work in everyday operations. This is precisely where theory is separated from reliable operational reality in RFID projects.

8. Evaluate providers based on support, roadmap, and industry understanding

In addition to the product itself, the provider also matters. Companies should check whether regular updates, transparent further development, project experience, and reliable support are available. It is equally important whether the provider understands the industry-specific requirements, for example in retail, manufacturing, warehouse logistics, or healthcare. Good RFID software is not only technically suitable, but also organizationally compatible.

Typical functions for the use of RFID for logistics service providers, retail, and industry:

• Electronic stock-taking using barcode scanners, RFID readers or smartphones, etc.
• Storage location management
• Order processing, goods receipt, putaway, stock transfers
• Multi-site, management of multiple warehouse locations
• Management of missing items, dangerous goods, etc.
• Block storage management, storage and retrieval strategies in block storage, return racks, drive-in racks, etc.
• Replenishment of the picking warehouse, consolidation
• Container accounting, pallet statistics, monthly statistics, etc.
• Report management
• Mobile data collection using wireless data terminals or pick-by-voice
• Minimum stock monitoring, EAN barcode management, shelf labels
• Dispatch, route allocation, recording of dispatch data and packing lists, dispatch labels, packing volume
• Quality assurance, batch management, quarantine, customs hold, expiry date monitoring, temperature monitoring, etc.
• Multitenancy
• Multi-user capability
• Mass changes

Additional specific criteria and question prompts for evaluating Radio Frequency ID software:

• As not every printer can automatically process every RFID label, please clarify what requirements apply to the labels. Requirements may, for example, relate to the distance between two consecutive transponders or the need for a so-called black mark (control mark on the underside of the label carrier). It is therefore essential to check in advance whether the desired labels can be processed by the relevant printer, or which labels can be used with existing printing systems.
• Ask about simulation functions. This allows you to test signal waveforms and RFID read events in advance without having any RFID hardware installed.
• Find out which RFID readers can be used. In an office environment, for example, slim devices can be installed almost invisibly under a desk top, allowing entire stacks of files or books to be scanned at once. The location of files or books can then be checked from any PC on the network.
• Check which tag types are supported by RFID-enabled printers. As there are over 500 different types available on the market, it is important to check which ones are supported by the software.
• Ask which data formats the software supports for RFID tags. Are the formats you need included? If necessary, can you also specify your own custom RFID data formats?
• Is the software compliant with the EPCglobal Consortium’s ‘UHF Generation 2’ standard? If it is EPC Gen 2 compliant, you can use the software with a wide range of RFID-enabled printers.
• If you ensure Unicode compliance, this simplifies international use. When encoding text onto an RFID tag, you can use Unicode to represent most of the world’s languages.
• Ask about the display options for tags on the screen (RFID antenna, etc.). This will make it easier for you to see if you are attaching a label in a position that is unsuitable for use.
• Please ask whether the command sequences used can be displayed; this will make it easier to integrate them into your applications.
