PLEASE help! How to load Square reader bar files onto z10
Ok, I realize I'm not good at a lot of things technology-related.
I'm really trying to load the Square app onto my z10 so that I can accept credit cards for my business/related charities. I've got the (physical) reader. Thought the best/easiest way to do this would be to go the Chrome route (drag and drop is our friend, right?). I have watched the damned video on how to do this on CB what feels like 100 times.
Loaded Chrome onto my pc. Downloaded the Square app from the Chrome store. Enabled developer mode on my z10. Found the "bar" file, tried to download it. Windows said it couldn't read the file. Found opensource software that was supposed to open bar files. Downloaded that. Tried to download the Square app from the Chrome app store again. STILL can't open/read the bar file. WTH?
I realize I'm probably missing a very simple step. But what the he11 is that step? It shouldn't be this hard to get something to work. Should it?
z10 model stl100-3 software 10.1.0.2019
Can anyone help me? Thanks.
