US Patent 10915900 Interchange action delay based on refund prediction

Techniques for leveraging a likelihood that a transaction (or a portion thereof) will be associated with a refund request to determine whether and/or how long to delay sending, to a payment service, a request for processing the transaction (or portion thereof) are described herein. In an example, a payment processing service may receive, from a point of sale device operated by a merchant, transaction data associated with a transaction between the merchant and a customer. The payment processing service may determine a likelihood that the customer will request a refund for a cost of an item of the transaction at a time after the transaction. Based at least partly on the likelihood, the payment processing service may determine whether to wait until at least the time before sending, to a payment service, a request to process the transaction data for at least the cost of the item.
