In the era of IoT-driven and digital intelligence, as an useful tool, UHF RFID Inlay has become an indispensable core component in automatic identification and data collection. As one of the most professional suppliers of smart cards and smart tags with 20 years of industry experience, Zhanfeng Smart Card is committed to popularizing professional knowledge of UHF RFID Inlay and providing high-quality solutions, products and services for global customers.


First, let' s clarify what UHF RFID Inlay actually is. Simply put, UHF RFID Inlay refers to the core part of UHF RFID cards and tags, consisting of a tiny UHF chip and an antenna. And the chip usually encapsulated in PET or other durable materials without adhesive or additional packaging. The inlay works in the 860-960MHz global UHF frequency band, complying with EPC Gen 2 (ISO 18000-6C) standards, which ensures its wide compatibility  to the machines and global applicability.


Compared with other HF or LF RFID inlays, UHF RFID Inlay has unique advantages that make it stand out in many industries. The most prominent feature different form other inlays is its long reading distance. Passive UHF RFID Inlay can achieve a reading range of 3-12 meters under normal configuration, and even more than 15 meters with optimized equipment. This distance is far superior to HF inlays that only work within a few centimeters. In addition, it supports batch reading of multiple tags for people at the same time, which can quickly identify dozens or even hundreds of tags in one scan. This greatly improves the work efficiency, especially in scenarios such as warehouse inventory and logistics sorting.


For the above advantages, the application scenarios of UHF RFID Inlay are extremely extensive. In the retail industry, it is embedded in clothing tags to realize rapid inventory counting and anti-theft management, solving the problem of low efficiency of old and traditional barcode scanning. In the logistics and supply chain field, it is used to track goods and pallets, realizing full-link traceability from raw material procurement to terminal sales. This tracking reduces manual errors in transportation and storage. It also plays an important role in asset management, such as tracking IT equipment, medical instruments and outdoor facilities. With strong environmental adaptability, UHF RFID Inlay can withstand harsh conditions such as high temperature and humidity.



As for the types of UHF RFID Inlay nowadays, there are mainly dry inlay and wet inlay. Dry inlay has no adhesive backing, suitable for embedding into custom labels, smart cards or other products. And the wet inlay is added with adhesive, which can be directly pasted on the surface of objects, widely used in retail goods and inventory tracking. Both types of the inlay can be customized in size, chip model and performance parameters according to different application needs of the customers.
