So apparently I made a super-lightweight Point-of-Sale app for my local association, I could build it for a very old Android tablet, and I'm gonna crash-test it this weekend at our game convention.

Wish me luck 👍️

Side-note: most point-of-sale apps are bloated, internet-only, or too complex for what I needed, hence why I created a simpler one.
