SML Group Launches Latest GB25U8 Inlay - the first spec H inlay


DALLAS, TEXAS, 8th September 2020: RFID technology leader, SML Group has today announced the latest addition to its range of high-performance RFID inlays, the GB25U8. As the first spec H inlay, the GB25U8 has been designed for the apparel retail industry equipped with a highly sensitive RFID Ucode 8 chip from NXP.


The GB25U8 RFID inlay is fully compliant with the GS1 EPC/RFID Gen2v2 standard, supports RFID with global UHF frequencies. It also meets a number of Auburn University RFID Retailer Performance Specifications including: Spec A, Spec B, Spec C, Spec D, Spec M, Spec G, Spec F, Spec N, Spec Q, Spec W1, Spec W2, Spec W3, Spec W4, Spec W5, Spec W6, Spec L, Spec H, Spec I, and Spec K. (All active retail specs)

The new SML inlay can be implemented in the vast majority of tagged products at retailers that are using RFID solutions to improve inventory accuracy, improving the consistency and speed of RFID stock counts. Measuring at 70 x 15mm, the GB25U8 RFID inlay is the first inlay within the RFID industry history to pass all active categories including F, I, H, and Ws. As a result, the inlay is an optimum choice for omnichannel retailers to be deployed across their stores and supply chains.

In addition to supporting apparel, footwear and home products, the new tag can also be used to help manage other items including; cosmetics, wine & spirits, pharmaceutical and food.

With the advantage of the innovative antenna, the inlay is not only very powerful on forward sensitivity, but also strong on reverse backscatter signal.
