Garmin Pay unsuccessful under low battery

Hi everyone,

I have noticed several times now that paying with Garmin Pay did not work with my VA3M. Every time was very painful as the cashier had to take back the items I wanted to get (after workout). The terminal did not get recognized by the watch and vice versa. I believe every one of these failures was in a low battery range. Somewhere underneath 20%. 

Could that be a reason for lower sending "power" of the NFC? Has anyone else noticed that?

 If not it could only be a hardware issue.
