How to avoid signal interfere each other between two rfid reader or more

Hi..

I have RFID Multireader (2 Reader) project with arduino. I use RFID longrange 125Khz. How can I manage the code/program/logic to make my RFID not interfere each other?
Note :
In my project those two RFID antenna must be placed side by side or separate 1 cm each other.
Should I create 1 module with 2 antenna? or 2 module with 2 antenna?

I have try array system in arduino to cut off ground line (flip flop) to each rfid module (2 rfid), the result 1 rfid work well but the other is abnormal.

I also have try array system with relay to cut antenna line (flip flop) with delay 200ms, the result sometimes 1 anntenna work well but other antenna is abnormal.

Anyone can explain how to implement this method in arduino?

Thank You...

Hi,

Your project sounds interesting but I am afraid I cannot offer any specific advice. This forum is more specifically for our ClearStream software

If I had to completely guess, you may have a hardware issue with one of the modules or your code is not quite correct in handling multiple modules at the same time.

In an increasingly interconnected world, the use of RFID technology raises important questions about privacy, security, and individual autonomy. As we embrace the benefits of RFID in various applications, it is crucial to engage in thoughtful discussions about the ethical implications and potential risks associated with its widespread adoption.
