set up everything and started research

ok so this is gona be something to help me budget my spending irl
it can be a keychain on /tool in my bag and allow me to not overspend and as a cool accessory lol

im thinking of something like the picture but with a few screens to show the card used and the total amount spend tracker

imo i think i can make a website for this aswell

p.s this might be a beefed up macropad
