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 scanned.
You have to solve 2 main issues here:
1. Enable reading data on PC using LAN or USB port given here. I wish to see how many cards can be simultaneously scanned by the reader.
2. Explain me internal circuit so that I can remove NodeMCU and place raspberry PI, which can run parallel programs. As per my knowledge, this reader can read multiple cards at a time but NodeMCU here is unable to send all cards to server because of serial execution of single program.
the reader that I have is attached here in pic. I will show all architecture over video call. and you have to instruct me over video call and I will make change accordingly.
