Abstract: A merchant uses a merchant point of sale (POS) device to identify items or services for purchase by a customer, and costs for each. One or more payment amounts are sent from the merchant POS device to a checkout server using an application programming interface (API), which the checkout server sends on to an authorized payment terminal device that then reads payment information from a payment object and sends the payment information back to the checkout server. The checkout server processes the transaction and confirms transaction completion to the merchant POS device and payment terminal device.

Abstract: Application integration for contactless payments is described. In an example, a payment making platform can provide a transaction code to a payment processing platform. The transaction code can be presented at a point-of-sale of a transaction between a customer and a merchant associated with the payment processing platform. Upon detecting an interaction between the transaction code and a computing device of the customer, the payment making platform and the payment processing platform can exchange data to enable the customer to participate in the transaction via the computing device of the customer. In some examples, the payment making platform and the payment processing platform can process a contactless payment for the transaction by transferring funds associated with an account of the customer from the payment making platform to the payment processing platform for depositing into an account of the merchant.
