A USB RFID Reader is a device used to read RFID tags using a USB connection to a computer or other device. It typically consists of an antenna, a transceiver, and a decoder, similar to other types of RFID readers. USB RFID readers are commonly used in applications where data needs to be quickly and easily collected and transmitted to a computer or other device. They are often used in retail settings for inventory management, asset tracking, and point of sale transactions.
