Android QR PAY and AIDL Integration -- 4

We are starting a project to develop a QR code payment application called "Metropol Pay" that will run on the Android platform. The application will be designed to perform the following basic functions, with a user-friendly interface: get tokens QR code creation Payment inquiry Cancellation and refund procedures These functions will be exposed via AIDL and can be triggered via App2App from another application. The application will manage Metropol Pay's payment processes, show the user the QR code and query the transaction details. When opened, Metropol Pay will receive a token with a 5-minute validity period from a Token API, then generate the QR code and display it on the POS screen. The screen will be designed to be user-friendly and informative, and the necessary feedback will be given to the user during the payment and return processes. In addition, a simple test application will be developed for the verification and testing processes of the project and each stage of the application will be tested in detail. When the project is completed, all documents, including source codes, will be delivered. We aim to complete the project within 1 day and the project budget is determined as 200 dollars. If you are ready to start immediately, we are waiting for your offer.
