US Patent 11410153 Enrolling mobile-payment customers after online transactions

Techniques described herein are directed to, among other things, enabling the use of contactless payment technology when customers and merchant are remote from one another by, for example, authorizing merchants to use payment hardware components residing on customer devices. For example, when a customer requests to purchase an item from a merchant via a ecommerce page of the merchant, a payment-processing service may authorize, at the request of the customer, the merchant to use an NFC reader residing on the customer device to accept payment information from a contactless card of the customer for satisfying a cost of the transaction.
