Service information

An RFID label includes a tiny radio chip and antenna embedded inside a normal adhesive label. This allows you to stick it on an item and later read its data wirelessly (no direct line-of-sight needed). We use high-quality RFID inlays from top manufacturers, ensuring dependable read range and compliance with industry standards (like UHF EPC Gen2 for logistics or HF/NFC for close-range applications).

As a result, our labels work seamlessly with standard RFID readers and systems. We can provide labels tuned to whatever frequency or application you need – be it long-range UHF tags for warehouse inventory or HF/NFC tags for item-level identification.

We also customise RFID labels to suit your use case. They can be made in various sizes and formats – from small tags for individual assets to larger labels for pallets. You can receive them blank (to print and encode with your own RFID printer) or have us supply them pre-printed and pre-encoded with your required data.

Our team can assist with the encoding setup to ensure each tag carries the correct information and unique IDs. Quality is paramount: we test our RFID labels to confirm each chip works and is correctly encoded before delivery. Kelgray guarantees a steady supply too – whether you need a one-time bulk order or ongoing shipments, we have you covered. If you’re new to RFID, we’ll gladly support you with guidance and technical help to ensure your RFID deployment is a success.

Our Frequently Asked Questions

Here are all of the answers to your most common questions around RFID Labels :

A: RFID labels are labels that have a tiny RFID chip and antenna embedded in them, which enables wireless identification of objects. In practice, an RFID label looks very much like a regular self-adhesive label (it can have printed text or barcodes on it too), but inside it contains an RFID inlay (the chip + antenna). When you apply the label to an item, that item can then be identified at a distance using an RFID reader. The reader emits radio waves that power the chip in the label and allow it to communicate its stored data (like a unique ID number). This means you don’t need direct line-of-sight like a barcode – you could read through packaging or scan many items at once. RFID labels are used for things like tracking inventory in a warehouse (you can scan a whole pallet of products quickly), managing assets, or even in retail stores for security and checkout. To summarise: an RFID label is a smart label that carries info on a microchip, which can be read remotely by radio frequency, greatly speeding up and automating identification processes compared to manual or barcode methods.

A: Our RFID labels adhere to global standards, so they should work with any standard-compliant RFID system. For example, if you have UHF RFID readers (the common type for supply chain/inventory use, following EPC Gen2 / ISO 18000-6C standards), our UHF RFID labels will be compatible. Similarly, if you use HF/NFC technology (often used for short range or consumer-facing applications, like scanning with a phone or for library books), we can provide HF labels that meet ISO 14443 or 15693 standards. The important part is to match the label’s frequency and protocol to your readers. We will help ensure you get the right type. In practice, most modern RFID systems are standardized: a Zebra, Impinj, Honeywell, etc. reader will all read a properly encoded EPC Gen2 UHF label. So if your system is already in place, just tell us what it is and we’ll supply labels that are confirmed to work with it. Additionally, our labels can be provided either blank (so you can encode them with your own RFID printer/encoder on-site) or pre-encoded (we encode each tag’s data to your specification). Either way, they will integrate with your database or software. We can even help with testing a sample: we often send a few sample RFID labels to a client to test on their system first, if there’s any doubt. But overall, yes – our RFID labels will work with existing standard RFID infrastructure, and we’ll make sure to match the right product to your setup.

A: RFID labels come in many sizes and formats – we offer a broad selection and can customise as needed. The size can range from very small (a few centimeters across, for tagging individual retail items or small assets) to much larger (like a large label for pallet tagging). Common sizes include things like 4×2 inch labels or 2×1 inch labels for general use, as well as special form factors like square tags (e.g., 50x50mm) or even very slim, long labels for certain tracking needs. The format can be paper or synthetic material depending on durability needs (synthetic labels are more rugged, water-resistant, etc.). We also have on-metal RFID labels (with a special backing so they can be used on metal surfaces without interference) – these are a bit thicker usually. If none of the standard sizes fits your requirement, we can produce custom dimensions or die-cut shapes. Additionally, RFID inlays (the actual chip+antenna) come in different sizes, so we choose one that fits within the label and meets the performance needed. We’ll consider the range you need and the surface you’re labeling to pick the right inlay and label size. Essentially, whether you need a tiny clothing tag, a label for IT assets, or a big durable label for a shipping container, we can supply an RFID label in an appropriate size/format. Just let us know the intended use and if you have size constraints, and we’ll propose options.

A: Yes, definitely. RFID labels can serve a dual purpose: they have the electronic RFID chip, but you can also print them with text, barcodes, logos, etc., like any standard label. In many cases, RFID labels are used in a way that the human-readable info and barcodes are printed on the label, and the RFID chip carries the same or additional data electronically. We can provide RFID labels blank (which you would print on using an RFID-enabled printer – it prints the surface and encodes the chip in one go) or pre-printed by us. If we pre-print, we can also pre-encode the RFID data to match the printed information. For example, if you wanted each label to show a barcode number and also have that number in the RFID chip, we can handle both printing and encoding in our production. The materials we use for RFID labels are the same types as normal labels (printable paper or synthetic face stock), so the print quality for text/barcodes is excellent. Long story short: you don’t have to choose between barcodes and RFID – our labels can absolutely do both. This is great for redundancy (if one method fails or if not all stations have RFID readers, the barcode can be a backup). We can help set up the printing/encoding process too, to ensure the data printed matches the data encoded.

A: Yes, we do. We realize implementing RFID might be new or challenging for some clients, so we offer support at various stages. If you need help with encoding, for instance: when we supply blank RFID labels, we can also help configure your RFID printer or provide guidance on how to format the data (EPC format, etc.). We can supply sample labels for testing and help troubleshoot any issues with read/write if they arise. If you don’t have RFID printing capability or prefer not to do it yourself, we can pre-encode the labels for you according to a spreadsheet or range of numbers you provide. Regarding broader implementation: we can advise on tag placement (where on your product or package to apply the RFID label for optimal reading), reader setup basics, and how to test read ranges. While we are a supplier of the labels and tags, our team has considerable RFID knowledge from projects we’ve done. We often collaborate with RFID integrators or your internal team to make sure the labels we provide work smoothly in your system. So, if you have questions like “How do I commission these tags?” or “What data format should I use?”, we’re here to help with those as well. Our goal is not just to sell you RFID labels, but to ensure your RFID project is successful – that might mean a bit of technical support or best-practice sharing along the way, which we’re happy to provide.

A: In general, most RFID labels we supply are intended for single-use – that is, once applied to an item, they stay with that item (or its packaging) through its lifecycle, and you wouldn’t typically re-encode and reapply them to something else. For example, RFID labels used in retail or logistics are usually one-time identifiers for a product or shipment. That said, the RFID chip inside can technically be reprogrammed multiple times (many allow rewriting), so in some cases customers do repurpose tags. However, because the label itself is an adhesive label (often with a tamper-evident or strong adhesive), removing it can damage it, and it may not stick well a second time. If you are looking for reusability, there are RFID hard tags or special RFID labels designed to be removable/reusable (like asset tags with durable backing). We can provide those types too, but they’re a bit different from standard labels. Typically, in a hospital setting for patient wristbands, RFID wristbands might be disposed after use; in supply chain, labels are one-and-done on a box or item. So, think of the standard RFID label as one-time use for practical purposes. If you need something reusable, let us know and we can discuss suitable products (like durable asset tags). But for most scenarios, plan that the RFID label will be used on one item and not removed/reused after that item’s done with. The chip itself could be locked or reused (if not locked), but the physical label usually isn’t transferred to a new item effectively.

A: RFID labels have an electronic component (the chip and antenna), which means they’re a bit more complex than a paper label from an environmental perspective. The antennas are often aluminum or copper, and the chips are silicon – these are very small, but it does introduce materials that aren’t biodegradable. However, there are efforts to improve their eco-friendliness. For example, some RFID inlays now use aluminum antennas printed on paper or etching techniques that reduce waste, and we can source labels that use more sustainable manufacturing processes. The paper or PET (plastic) facestock of the label can be chosen to be recyclable or made of recycled content. The overall impact of an RFID label is similar to a regular label with a tiny electronic inlay. We do offer certain “green” RFID labels that use less synthetic material or antennas that can be pulped with paper (for instance, there are paper-based NFC tags). Also, because RFID can improve inventory management, some argue it leads to sustainability gains by reducing waste/loss in supply chains. At the end of life, an RFID label on a package typically goes through the normal recycling stream – the tiny chip/antenna might be filtered out as residue. If you have strict sustainability goals, let us know: we can use recyclable facestock, or look at RFID inlays without plastic substrates, etc. Additionally, we encourage recycling of the label liners and any packaging from the labels we deliver. So, while RFID labels aren’t 100% biodegradable, we do what we can to minimise their footprint (and the efficiency they bring often offsets some environmental costs in other areas). We’re happy to discuss options like Eco RFID inlays if that’s a priority for you.
