An RFID (Radio Frequency Identification) sticker reader is a device used to read the information stored on RFID stickers or tags. An RFID sticker reader uses radio waves to communicate with an RFID tag, which responds by transmitting its unique identification number or data. These readers are commonly used in transportation, inventory management, access control, and many other applications where tracking and identification of objects is essential. RFID sticker readers come in various sizes, from handheld devices to stationary or mounted readers, and are used in a wide range of industries for various purposes.
