Garmin Pay?

If I had to guess, probably next large firmware update. This device isn't set to launch outside of Best Buy until mid to late October, so we probably wont get much aside from stability improvements in the mean time. Basically, we are in the early adopter phase.

Any ideas when Garmin Pay will become available?

Depends where in the world you are. UK I am hearing early 2018. US probably next month.

So will FitBit Pay become active before Garmin Pay? A big reason for my preorder was to use Garmin Pay, but not surprisingly the "big feature" that was being touted is coming soon...

Fitbit pay is also not def for launch either
