RFID tags
RFID tags are small electronic devices that use radio waves to transmit information. They consist of a chip and an antenna, allowing them to communicate with a reader. RFID tags can be passive, active, or semi-passive, depending on their power source. They are commonly used for tracking items in various industries, such as retail, logistics, and healthcare.
These tags can store a unique identifier and other data, making them useful for inventory management and asset tracking. When an RFID reader sends a signal, the tag responds with its information, enabling quick and accurate data collection without needing direct line-of-sight, unlike traditional barcodes.
