I am looking for very cheap, small and effective Arduino Yun compatible RFID reader for real time RFID tags ID and distance tracking, that does not require additional antennas and no GPS. RSSI known as not accurate for distance measurement. 10 meter distance coverage with 20 cm accuracy could be enough for now.
I want RFID sensor on microcontroller (Arduino Yun) be able to speak with PC local webserver JavaScript (connected to PC trough USB or WiFi).
Are anyone familiar with any suitable hardware and easy setup?
I have never done hardware development before.
