We got an existing POS system thats running on esp32. The system as it is now designed so that a unit is configured on startup via making a wifi hotspot, there you select an amount and amount of pulses for an amount. We now need to add a touch screen to the setup, on this touchscreen a splashscreen is needed. And on click on the screen you need to be able to select an amount and display a qr code. 2nd option must also be added, so that an amount can be set with on touchscreen keyboard. What I imagine in the setup process is that we start by selecting pos type: 1. Normal pos 2. Touchscreen fixed amounts 3. Touchscreen add amount on screen. Your job will be to draw up schematics and add above mentioned upgrades. Payment will ONLY be over freelancer and only when we are satisfied. Also what you bid is what you get no more so don't ask for more.
