8 Common Forms And Applications Of UHF RFID Tags

Generally speaking RFID tags can be divided into low-frequency(LF) RFID tags, high-frequency(HF) RFID tags and UHF RFID tags in several categories, but these tags consume a huge amount of scenarios are almost always using UHF RFID tags, which mainly stems from the following advantages.

(1) UHF RFID tags are read farther away;
(2) UHF RFID tags security, confidentiality;
(3) UHF RFID tags can identify objects in high-speed motion;
(4) UHF RFID tags can simultaneously realize the synchronous recognition of multiple objects;
(5) UHF RFID tags can be reused and have large data memory.

Diversified application scenarios label product form rich:

As different industries and application scenarios have significant differences in demand and use conditions, different requirements are put forward for the performance and form of tags. This is mainly based on the balance of business needs, process conditions, application costs, application scenario environment and other aspects, for example, the identified object is metal products, it is necessary to add wave-absorbing materials to achieve the characteristics of anti-metal.

RFID Tag products can be roughly divided into three categories from the form, respectively, the traditional self-adhesive self-adhesive tag, injection molding type tag and card type tag. The traditional self-adhesive RFID tag will RFID package into self-adhesive form, suitable for application in highway, parking lot and industrial production line product information automatic collection and other scenarios. In campus, traffic, access control and other scenarios, more contactless IC cards are used, and shaped tags made by injection molding process are also easily seen in access control.

In addition, because different countries and regions are not the same in spectrum allocation, the coverage of UHF RFID tag band definition is also different, for example

(1)China's band is: 840~844MHz and 920~924MHz;
(2)EU band is: 865MHz~868MHz;
(3) Japan band: 952MHz~954MHz;
(4) Hong Kong, Thailand, Singapore: 920MHz~925MHz;
(5) U.S., Canada, Puerto Rico, Mexico, South America band: 902MHz~928MHz.

UHF RFID common applications and tag form:

(1)Footwear retail industry - coated paper rfid hangtags/ rfid woven labels

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

Footwear industry on the introduction of RFID technology is the whole process, from the factory to the warehouse, and then to the retail terminal. It can automate the data collection of each operation link such as garment warehouse arrival inspection, inbound, outbound, transferring, moving and shifting, inventory counting, etc., to ensure the speed and accuracy of data input in all aspects of warehouse management, and ensure that the enterprise timely and accurately grasp the real data of inventory, and reasonably maintain and control the enterprise inventory.

In terms of the footwear retail market, the popularity of foreign brands for UHF RFID tags is much higher than that of domestic brands. This is mainly because foreign brand stores around the world, and fashion FMCG products on the high mobility requirements of goods, the use of RFID tags can be a great improvement in the efficiency of product circulation management.

(2) Ceramic RFID tags

Ceramic RFID tags is based on ceramic material package electronic label, has high electrical characteristics and high performance resistance, fragile anti-transfer. The electronic label antenna stopped on the ceramic substrate has small dielectric loss, good high level characteristics, stable antenna performance and high sensitivity. Mostly used in logistics storage, intelligent parking, production line management, anti-counterfeiting detection and other fields

(3) ABS RFID tags

ABS RFID tag are common injection-molded tag that are commonly used in logistics management scenarios. It can be installed on the surface of metal, wall, wood and plastic products, and is resistant to High Temperature and moisture for harsher working environments due to the strong protective function of the surface layer.

(4)RFID laundry tags

RFID silicone tags use silicone encapsulation technology, mostly used in the laundry industry, because silicone is soft and deformable, with high temperature resistance, rub resistance and other characteristics, commonly used in the inventory management of towels, clothing products.

(5)RFID Nylon cable ties

RFID cable tie tags are generally encapsulated with PP+nylon material, with excellent characteristics such as easy installation and removal, waterproof, high temperature resistance, etc. They are commonly used in logistics tracking, food traceability, asset management and other fields.

(6) Drip adhesive PVC card tag

The card made of PVC material can be customized for the shape so that the card has the appearance and texture of an artifact and effectively protects the internal chip and antenna, making it easy to carry. It can be used for access control, item identification management, game chips, and other scenarios.

(7) PET RFID Tag

PET is the abbreviation of polyester film, polyester film is a kind of polymer plastic film, because of its excellent comprehensive performance and increasingly favored by the majority of consumers. It can block ultraviolet rays, good resistance to high and low temperatures, and good creep resistance. As China's production volume and technical level still can not meet the market demand, some still need to rely on imports, PET labels are commonly used in jewelry management scenarios.

(8)PPS RFID Laundry Tag

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