Hi, @Picartso-123 ! Welcome to the Square Community! We are so happy to have you.
Can you give some more information? Which Square reader are you trying to pair? Is it a first generation or second generation?
This Support Article provides great troubleshooting steps to try to get the reader to pair. Please let me know if this is not the right reader or if these steps don't work. I'll be on the lookout for your response.
I hope this helps!
