  • Publication number: 20230004966
    Abstract: A proof-of-payment system that allows smart connected devices to confirm a payment information. In one example, a smart connected device that comprises a computing device and program instructions. The program instructions, when executed by the processor, cause the computing device to at least retrieve an encrypted proof-of-payment (PoP) payload from a blockchain and decrypt the encrypted PoP payload to retrieve a first identifier from the encrypted PoP payload. The first identifier from the decrypted PoP payload is matched to a second identifier presented at the smart connected device. An action is triggered in response to the first identifier from the encrypted PoP payload matching the second identifier presented at the smart connected device.
