SML Announces the GB4M700 inlay- helping retailers boost efficiency, whilst lowering material and shipping costs

Made with the Impinj M700 series of integrated circuit (IC), the inlay will help retailers boost efficiency and reduce the total material and shipping costs.

The inlay, which measures at 42x16mm, maximizes performance, achieving a capability that previously only larger inlays could reach. The small size and level of efficiency of the new GB4M700 inlay will significantly increase inventory accuracy and management for omnichannel retailers.

Additionally, the GB4M700 inlay has industry leading read sensitivity of -24 dBm with a small size antenna and contains a chip memory of up to 128 bits EPC, setting a new benchmark for all RFID products. The new SML RFID inlay can also be fitted on the vast majority of tagged products, improving the consistency of read performance for inventory tracking in large scale retail deployments. In addition to supporting clothing and denim tags, the inlay also supports the tagging of polybags and boxed items.

Dean Frew, Chief Technology Officer and Senior VP of RFID solutions at SML Group, commented, “SML RFID is committed to delivering the most innovative solutions to empower retailers to better manage their inventory. As a result, we are continuing to invest in our technology.  SML RFID’s design team and operational team, alongside our suppliers and Impinj have worked relentlessly to deliver the new inlay. The product will extend SML RFID’s innovative legacy and commitment to provide retailers and brand owner customers with innovative RFID solutions.”

Gahan Richardson, SVP Platform Product Management and Silicon Sales from Impinj also commented “We are delighted to see SML RFID leverage the advancements of the new Impinj M700 RAIN RFID tag chips. The SML RFID GB4M700 inlay will be the latest addition to meet demands of retailers for higher levels of inventory management”.
