A system and method for processing digital payments using a smart chip payment acceptance module associated with an Internet of Things (IoT) or vending device via a virtual EMV terminal process for cloud-based digital payment transactions. A short-range communication channel is provided between a mobile user device and the payment acceptance module. The mobile user device includes a wallet application with an integrated merchant application used to create a payment transaction. An unlock device enables digital secure remote payments (DSRP). A smart chip server connected to a payment gateway can generate an encrypted proof of payment (POP) message indicating completion of the payment transaction. The user can complete the payment transaction using the integrated wallet application within the user device in an online or offline mode of the vend device for seamless interaction with the system by a new user as well as improved flexibility for merchants and consumers.

Smart chip payment acceptance

A method for carrying out a cryptocurrency blockchain transaction through an integrated circuit payment card using a multi-signature blockchain wallet includes: storing, in an integrated circuit of a payment card, a first private key of a first cryptographic key pair and a transaction account number; receiving, by the integrated circuit, a blockchain transaction from a point of sale device, the blockchain transaction including unspent transaction outputs, destination addresses, a cryptocurrency amount for each destination address, and a first digital signature generated using a second private key of a second cryptographic key pair; digitally signing, by the integrated circuit, the blockchain transaction using the first private key to generate a second digital signature; and transmitting, by the integrated circuit, the digitally signed blockchain transaction including the first digital signature and the second digital signature to the point of sale device.

A system for initiating secure guest checkout includes an application server; and an untrusted user interaction device that is in communication with the application server. The untrusted user interaction device has a unique device identifier that is registered with the application server. The untrusted user interaction device is configured to: receive input data relating to a selection of one or more items; transmit, to the application server, the selection of one or more items and the unique device identifier, for creation of a cart at the application server; communicate a pairing code received from the application server, the pairing code being associated with the cart; and wirelessly broadcast identifier data including, and/or derived from, the unique device identifier; such that a computing device that receives the identifier data and the pairing code can verify the unique device identifier and retrieve the cart from the application server for initiation of a secure remote commerce (SRC) checkout process at an SRC initiator.

A method, performed by an initiator system, for securely initiating a checkout with an enrolled device includes the steps of receiving, from an untrusted device, a checkout request including a user identifier; determining whether the user identifier is associated with one of a plurality of enrolled devices in an enrolled device database; responsive to a determination that the user identifier is associated with an enrolled device, retrieving user data associated with the user identifier; sending, to the untrusted device, a request for instructions to perform a checkout with the enrolled device; receiving, from the untrusted device, instructions to perform the checkout with the enrolled device; generating a request to perform the checkout with the enrolled device; and initiating a checkout by sending, to a communication system, a request to initiate a checkout with the enrolled device over a secure communications channel.
