PayPay aims to solve the unnecessary use of voucher tickets in events by providing an in-app menu and payment platform for consumers to use. PayPay also provides automated QR generated receipts to consumers for vendors to verify the specific order and set whether the order has been claimed or not. Claimed orders act as a safety for vendors as consumers will not be able to use the same QR code twice as it will be rendered invalid once the vendor has clicked the claim button.
