RFID reader acts like a computer which sends signal to an antenna and then receives it back. It evaluates the data from RFID tags and then sends it, for example, to a cloud service or a server for further processing or analysis. Readers can differ in their performance, number of antennas they can use or in their protocols, which are used for the data evaluation.
