You can get a usb based, digital glucose meter from Bayer called the Contour USB. It even has a display built in.
It's potentially free after coupons if you are buying strips.
But the glucose meter market is a huge scam, with what is essentially 1 cent litmus strips being sold for $1 each - manufacturers are milking insurance for all it's worth and the people without insurance have to spend a small fortune.
I'm sure it's extracting many millions from the economy that could be far better used.
Now that's a racket I'd like to see a startup disrupt someday.

Not that I disagree with most of what you said but my mother is diabetic, recently diagnosed, and from what I can tell the strips have some sort of micro-channels.
You touch blood to one side or the other of a test strip, none of the blood is visible other than where it's touching the test strip. It gets to the meter internally through the strip almost instantly I'd say in less than half a second if not less, pretty much instantaneous.
Too bad there isn't an open source meter and cheaper strips.
By the way on Reddit there is r/diabetes if anyone wants to join whether you're diabetic or not.
