We use a variety of surface materials in our daily lives, and they have different functions, whether as a protective layer or for packaging. The surface materials used in the electronics industry are also quite abundant, such as ultra-thin polyester ammonia that is dust-proof and moisture-proof for keyboards, solid gel protective covers used to protect smart phones, smart tablets and displays, and with the continuous development of the technology field In depth, the military aviation and shipbuilding industries began to require surface materials to have “invisible” functions. In daily life, the most common surface material is our skin, which allows us to have a sense of touch, perceive changes in the outside world, protect our body from being infringed, and the fingerprints produced by the skin give each of us a unique uniqueness. sex.
RFID technology and new challenges of metal assets
The use of RFID technology on metal assets is no longer limited to the research scope of the physics community. The contradictory relationship between radio waves and metal depends on the contact between the radio waves and the surface of the insulating medium. Under different circumstances, metals may affect radio frequency. The signal has the effect of reflection, amplification and even interference, so that the RFID tag can play a completely different performance. And now these uncertain problems have been solved, the RFID technology used on metal surfaces or in metal environments has been completely overcome, and this tag can even be used on non-metal surfaces at will (the customer does not need to use other substances to separate Open the space of the tag antenna), the current RFID tags can not only read and write on the metal surface, but also can be embedded in the metal to exert excellent performance, such as Xerafy’s award-winning iN series of embedded tags.
Of course, the metal environment has more stringent requirements for the use of RFID. For example, curved assets need RFID tags that are soft, thin, and durable. The Xerafy Metal Skin that I want to introduce to you now is the world’s first real UHF EPC RFID inlay, which is specially suitable for metal asset tracking and flexibly applied to curved assets.
Now another major challenge of RFID technology is to replace the human-readable product serial codes, two-dimensional codes, and barcodes. Traditional RFID tags will be accompanied by a printed bar code to meet the requirements of manual reading. The reason is simple, because most of the RFID tags are thick and hard, which cannot meet the requirements of label conversion and printing.

Many multinational companies often have to use two different types of RFID tags when managing metal and non-metal assets. Only in this way can they achieve the desired reading distance, stable tag performance, and standard frequency bands in the region. Companies sometimes have to affix two or three tags with the same EPC but different regional frequency bands on the same asset to meet the needs of cross-regional asset tracking management.
Industries with cross-regional tracking and management of asset needs:
•Product delivery certificate (notebooks, IT assets, consumer electronics)
•Cylinder tracking (chemical substance container, beverage container)
•Pipeline tracking (natural gas pipelines, water pipes, industrial facilities, etc.)
• Industrial production equipment tracking
• IT server and asset tracking
•Mobile asset tracking (handheld devices, communication devices, scanning devices)
•Medical device tracking (medical with a unique product verification code•Global supply chain management
• Pharmaceutical certification in tin foil packaging
• Recyclable transportation equipment and containers, etc.
•Luxury retail
Case application analysis
IT asset management can be said to be one of the very classic and very reference applications in many RFID cases. It is suitable for existing enterprises to track their own assets in a wide range, and also for enterprises that need to automate the management of inbound and outbound records within the organization. As long as a fixed reader is installed at the doorway through which the asset passes, the distance is based on the width of the door. Generally speaking, tags with a reading distance of 1.5 to 3 meters can already meet the needs of reading and writing.

The read and write distance that Metal Skin can reach is not limited to the use of fixed readers. If installed on a box, computer or even a wallet, the tag can still achieve satisfactory read and write results. Andrew Nathanson, vice president of AutoID Group’s VDC Research Institute, once said: “The consumer electronics market is showing a demand for RFID applications, and this demand will develop rapidly in the next few years.”
If the company needs to track and manage a batch of iPads and laptops, most of these electronic products are made of metal materials, forming a complex environment with the surrounding non-metallic materials, and the size of small electronic products and components is also important for the installation of labels. It is extremely challenging. In addition to requiring RFID tags to be small and exquisite, they must also be light and thin, because the improper thickness of the tag can easily lead to signal detuning, and the size of the tag must also match the size of the electronic product.

The RFID solution brought by Metal Skin is fully capable of responding to many challenges in the current tracking management field: small size, flexible application to assets of various shapes, meeting the technical requirements of label composite printing, and full-band design. As a middleware of RFID technology, Metal Skin is a metal inlay that can be glued freely with adhesive. It has the characteristics of high cost performance and metal/non-metallic application. It can also be used as a disposable label in the general consumer market. , This will be an unprecedented revolution in RFID technology.
The performance of Metal Skin on the surface of metal and non-metal environments is basically the same, and it can achieve seamless installation and stable performance for most assets. The standard packaging of Metal Skin is 2500 pieces per roll, and the label can be printed directly with the printer. When packaging the inlay, users no longer need to make separate icons and QR codes to match the size of the RFID label.

Taking the tracking management of iPad and laptop as an example, Metal Skin is directly posted on the electronic device for reading and writing. However, the application of Metal Skin is not limited to this. You can also apply other types of printed labels or QR code labels on Metal Skin to apply to different equipment. This seamless product in and out management method is fully integrated within the enterprise. The safety management system and the employee responsibility system have realized the intelligent management of enterprise inventory in a true sense.
The application significance is reflected in:
•Safety management to prevent asset loss;
• Compatible with Sarbanes Oxley Act at low cost;
• A more convenient and efficient way of inventory management;
•Real-time tracking management reduces asset replacement rate.
in conclusion
Xerafy’s revolutionary product, Metal Skin, is opening up a new situation for RFID applications in various industries around the world. Its wide range of application areas also include: product certification, anti-counterfeiting, product traceability, medical equipment tracking in the maintenance and sterilization process, IT blades Server management and tracking management of reusable beverage containers in the catering system, etc. In this era of rapid technological advancement, the application of Metal Skin is far more than these, and there are still many tasks worth exploring in the future.
