8 common forms and applications of UHF RFID tags 2020-12-22
In recent years, due to the continuous deepening of people's cognition of RFID technology and the continuous reduction of application costs, RFID has continuously accelerated its penetration in various industries.

In the apparel industry, big-name shoe and clothing manufacturers such as Uniqlo, Decathlon, H&M, Hailan House and other large-scale application of RFID to improve the efficiency of the supply chain; libraries across the country have chosen to use RFID solutions to manage a large number of books, appearing in the library Various forms of products such as operator workstations, self-service book return boxes (machines), mobile inventory vehicles, sorters, etc.; airlines use RFID technology to track luggage in real time, which greatly reduces the luggage loss rate of passengers...

Although, generally speaking, RFID electronic tags can be divided into low-frequency RFID tags, high-frequency RFID tags and UHF RFID electronic tags, but these tags consume a lot of scenes almost all use UHF RFID tags. Derived from the following advantages:

(1) The reading distance of UHF RFID electronic tags is longer;

(2) UHF RFID electronic tags have strong security and confidentiality;

(3) UHF RFID electronic tags can identify high-speed moving objects;

(4) UHF RFID electronic tags can simultaneously realize the simultaneous identification of multiple objects;

(5) UHF RFID electronic tags can be reused and have a large amount of data memory.

Rich label product forms in diversified application scenarios

Because different industries and application scenarios have significant differences in requirements and usage conditions, different requirements are put forward for the performance and form of labels. This is mainly based on the balance of business requirements, process conditions, application costs, application scenarios, etc. For example, if the identified object is a metal product, it is necessary to add anti-metal properties by adding absorbing materials.

Electronic label products can be roughly divided into three categories in terms of form, namely traditional self-adhesive self-adhesive labels, injection-molded labels and card labels. The traditional RFID electronic label with self-adhesive function encapsulates RFID into a self-adhesive form, which is suitable for applications such as automatic collection of product information on highways, parking lots and industrial production lines. In campus, traffic, access control and other scenes, non-contact IC cards are often used, and it is easy to see special-shaped labels made by injection molding in access control.

(Some common RFID tag forms)

In addition, because different countries and regions have different spectrum allocations, the coverage of UHF RFID frequency band definitions is also different, for example:

(1) The frequency bands in China are: 840~844MHz and 920~924MHz;

(2) The EU frequency band is: 865MHz~868MHz;

(3) The Japanese frequency band is between 952MHz and 954MHz;

(4) Hong Kong, Thailand and Singapore: 920MHz~925MHz;

(5) The frequency bands of the United States, Canada, Puerto Rico, Mexico, and South America are: 902MHz~928MHz.

UHF RFID common applications and tag forms

(1) Footwear retail industry-coated paper tag label/woven label label

Among the many application scenarios of RFID, the most common is the footwear industry, which is also one of the areas where UHF RFID tags consume the most.

The introduction of RFID technology in the footwear industry is a whole process, from factories to warehouses to retail terminals. Automatic data collection can be performed on the data of each operation link of clothing warehouse, such as arrival inspection, warehousing, outbound, allocation, shifting, inventory counting, etc., to ensure the speed and accuracy of data input in each link of warehouse management, and to ensure that the enterprise Master the real data of inventory in a timely and accurate manner, and reasonably maintain and control enterprise inventory.

As far as the footwear and apparel retail market is concerned, the popularity of UHF RFID tags by foreign brands is much higher than that of domestic brands. This is mainly because foreign brand stores are spread all over the world, and fashion fast-moving consumer goods require high liquidity of goods. The use of RFID tags can greatly improve the efficiency of product circulation management.

(2) Ceramic electronic label

Ceramic electronic tags are electronic tags based on ceramic material encapsulation, which have high electrical characteristics and high performance resistance, fragile and anti-transfer. The electronic tag antenna restrained on the ceramic substrate has low dielectric loss, good high-level characteristics, stable antenna performance and high sensitivity. It is mostly used in the fields of logistics warehousing, intelligent parking, production line management, anti-counterfeiting detection, etc.

(3) ABS label

ABS label is a common injection-molded label, which is often used in logistics management scenarios. It can be installed on the surface of metal, wall, wooden products, and plastic products. Because the surface has a strong protective function, it is resistant to high temperature and moisture and is suitable for harsh working environments.

(4) Garment washing-silicone label

Silicone labels use silicone encapsulation technology and are mostly used in the washing industry. Because silicone is soft and deformable, it is resistant to high temperature and rubbing, and is often used for inventory management of towels and clothing products.

(5)RFID Cable Tie tag label

Tie-type labels are generally packaged with PP+nylon materials and have excellent characteristics such as easy installation and disassembly, waterproof, and high temperature resistance. They are often used in logistics tracking, food traceability, asset management and other fields.

(6) Epoxy PVC card label

The card made of PVC material can be customized for the shape, so that the card has the appearance and texture of handicrafts, and effectively protects the internal chip and antenna, and is convenient to carry. It can be used in scenarios such as access control, item identification management, and gaming chips.

(7) PET label

PET is the abbreviation of polyester film. Polyester film is a kind of polymer plastic film. Because of its excellent comprehensive performance, it is more and more favored by consumers. It can block ultraviolet rays, has good high and low temperature resistance, and has good creep resistance. As my country's production volume and technical level still cannot meet the needs of the market, some still rely on imports, and PET labels are often used in jewelry management scenarios.

(8)PPS laundry tag

PPS laundry tags are a common type of RFID tags in the linen washing industry. They are similar in shape and size to buttons and have strong temperature resistance. By using PPS laundry labels, washing management becomes more efficient and transparent....
