Trend of Flexible RFID Metal Label Applications

Due to the rapid development of the Internet of Things, various new products and technologies have been derived. In the process of RFID application, the identification of ordinary items has also been extended to the identification of metal items. RFID tags are also made of ordinary self-adhesive, Labels such as PVC and paper extend to metal-resistant labels.

When it comes to anti-metal labels, common RFID anti-metal labels mainly include PCB anti-metal labels, ABS anti-metal labels, ceramic anti-metal labels, Epoxy anti-metal labels, high temperature resistant metal labels, flexible printable anti-metal labels, etc.

The flexible anti-metal tag is an electronic tag encapsulated with a special anti-magnetic absorbing material. It not only technically solves the problem that ordinary electronic tags cannot be attached to metal surfaces, but also can be attached to curved surfaces like ordinary tags. It plays an important role in collecting data in extreme environments such as metals. The flexible anti-metal label (printable) has certain flexibility and can be bent. It has the advantages of good metal resistance, excellent performance, good directionality and long reading distance when used on metal surfaces. It can support fast reading and writing, non-printable Visual recognition, mobile recognition, multi-target recognition, positioning and long-term tracking management.

Variety Application Scenarios of Flexible RFID Anti-metal Labels

1. It can be used for asset management, management of metal assets, such as iron cabinets, electronic products, etc.
2. It can be used for IT asset tracking and pasted on the exposed part of IT server or equipment.
3. It can be used for follow-up inspection of recyclable transport items, such as pallets, containers, etc.
4. Used for warehouse management.
5. Suitable for the management of curved metal materials such as pressure vessels and cylinders
6. Anti-liquid bottle management

1. Size miniaturization

If the tag needs to have a long reading distance and a good reading effect, the requirements for the antenna will be very high, and the size of the tag needs to be larger. With the development of technology, the tag with small size and stable performance will become the mainstream. The early RFID flexible anti-metal electronic tags are often too large in size, which is not conducive to the expansion of application fields. With the development of intelligent manufacturing and smart medical care, the market demand for high-performance miniaturized RFID flexible anti-metal tags is gradually increasing. This kind of product is suitable for For the comprehensive management, identification and traceability of small and micro metal devices, such as medical equipment, metal tools, aerospace, etc., there is a huge market prospect.

2. Carrier flexibility

Common anti-metal electronic labels, such as PCB and ceramic labels, are relatively hard in texture and cannot be bent and folded. It cannot meet the market demand for UHF RFID tamper-evident tags. The RFID anti-metal tag with flexible structure can not only be bent to adapt to more corner and curved applications, but also can realize the anti-disassembly function, which makes up for the lack of hard tags and expands the application space.

3. Cost reduction

Rigid RFID anti-metal tags are mainly PCB antennas and ceramic antennas. The cost of raw materials is high. SMT (surface mount) or COB are mainly used on the packaging. The manufacturing cost is still high, especially for the subsequent coding and writing. Personalization work is difficult to carry out in batches. Usually, performance can only be tested one by one, which is difficult to detect, and product consistency will also be affected to a certain extent. These factors lead to high overall costs and affect the large-scale application of such labels. If a flexible RFID anti-metal tag can be used, the raw material cost is relatively low, and it can be mass-produced, which directly reduces the difficulty of subsequent personalization and quality inspection, and the cost can be greatly reduced.

After years of development, flexible anti-metal tag technology has made great progress, and the coverage of technical applications is wider, solving the problem that electronic tags cannot be attached to metal surfaces, allowing RFID technology to better interact with metal objects.
