    I bought a UHF RFID reader online. It comes with 2 built-in wifi modules (NodeMCU). One is set to tether hotspot which is used to change SSID and password for another module. the other module sends data to my server using that SSID and password. there is also a lan port and a pc software. That pc software can scan the module when attached to LAN, but it doesnot show any data when any rfid card is...
