You know, or you’re guessing?
Experience 
Have you ever used Bluetooth?
Maybe it uses @sams-club’s new Bluetooth app? 
i know it for a fact…
And how? You work there?
know from my sorce
it could be it works through tethering and the things in the store are connected to 24six servers
I would give you the solution mark if you could prove.
It would still be nice if they would say it works through Bluetooth instead of saying the above.
some thing like this but it has to do with something newer…
explain??
sorry patented proprietary can use wifi bluetooth…
Interesting that battery doesn’t drain fast if the Wi-Fi is constantly searching.
