QR Payment Integration for ESP32
Budget: $10 – $30 USD
I am looking for a proficient developer to design a payment system for the ESP32 microcontroller. The system should allow payment processing via QR code integration.
Key Aspects of the Project:
• Integration of a payment method with the ESP32 microcontroller - The selected freelancer should ideally have experience with ESP32 or ESP8266(NodeMCU).
• QR Code Integration - The payment system should allow for seamless transactions via QR code scanning.
• Payment Methods - As a preferred payment gateway, the system should be able to process transactions via Credit cards. Further methods could be discussed.
• API and JSON Usage - You should be conversant with using APIs and JSON for the integration process.
Preferred Skills:
• Experienced with ESP32 or ESP8266(NodeMCU)
• Proficient in APIs and JSON
• Prior experience in Payment gateway Integration
• Familiarity with QR code systems
We are looking for a developer who can create a payment system for esp32 or esp8266 (NodeMCU) devices. Development and programming are performed in the Arduino IDE. The task is to write code in such a way that when paying via QR code using a local bank's mobile application, the payment amount is displayed in the serial monitor.
It is also necessary to provide one button and two LEDs (green and red). When you pay $100 and press the button, the green LED should light up. When you pay $50 and press the button, the red LED should light up.
If you pay $200 and press the button, the green LED should also light up and the amount should decrease by $100, leaving $100 as a balance.
