What are RFID Wet Inlays?

RFID Wet Inlays are passive RFID tags with an adhesive backing, allowing them to function as ready-to-use, peel-and-stick RFID labels. Unlike dry inlays, which require embedding or lamination, wet inlays are pre-laminated onto a release liner with an adhesive layer, allowing immediate application to products, packaging, and equipment surfaces. This format is optimized for environments that demand speed, accuracy, and minimal manual processing.

Each wet inlay contains an RFID chip and antenna mounted on a thin PET or paper substrate. These components operate through passive backscatter communication: the antenna harvests the electromagnetic energy emitted by an RFID reader, powering the chip and enabling it to modulate and return a signal containing its stored data. This battery-free mechanism supports rapid scanning, high read rates, and reliable identification across standard HF and UHF frequency bands.

RFID wet inlays are widely used in retail labeling, shipping and logistics, consumer goods, apparel tagging, asset tracking, pharmaceutical authentication, and medical equipment identification. Their adhesive-backed construction enables high-speed automated labeling, simplifies large-scale tagging operations, and reduces handling effort when thousands or millions of items need consistent, accurate RFID marking.
