The Porduct is not sold seperately but rather a part of a much larger system so when the system sells it sells along with it.

The firmware of this product has significant potential for improvement. Currently, it relies on external libraries to operate the OLED display and RFID card reader, which may lack long-term stability. This dependency could pose challenges in commercializing the product. To enhance robustness, transitioning to direct implementations and minimizing reliance on external libraries would be a more effective approach.
