UX/UI Design

We need Screen designs for our application running on our Android POS Device. The screen of the POS device on which the mobile application runs is 480*800 and 4" We provide contact, contactless and magnetic card reading with the POS device. We also enable payment from the mobile application with the QR code we display on the screen. When the payment page of the POS device opens, we first expect contact, contactless and magnetic cards to be scanned. That's why we have to put the official version of the large Contactless Card Reader logo in the middle of this screen. We also want to show that it accepts contact and magnetic payments in a smaller way on the screen. We also want to put a logo on this screen showing that payments can be made with a QR code. When you click on this logo, a new page opens and the Payment QR code is shown in the middle of the screen. We do not accept physical card transactions on this screen. If the user wants to return to card payment, there must be a button on the screen. They can end their transactions with the "CANCEL" buttons on both screens. We countdown with a timer on both screens. We need two screen designs showing all this. We are waiting for senior and experienced candidates. The project must be completed within the day
