Garmin pay set up but not working

I set up Garmin pay a month or so back, and just started to try and use it the past few days for the first time. I tried at 3 different places, multiple times, but nothing works at all. The tap and pay usually works for watches (so say the cashiers), but I get nothing. I go to my wallet, put in the code, it says put near the reader, but nothing happens at all.
