A computer-implemented method is provided of processing payments to a merchant for selling goods or services to a consumer. The computer-implemented method comprises at a first time, receiving from the consumer a first payment made by a first payment instrument for a first purchase of goods or services, at a second time which is after the first time, receiving from the consumer a second payment made by a second payment instrument which is different from the first payment instrument for a second purchase of goods or services, and processing the first and second payment instruments to link the first and second payment instruments to the same consumer and thereby allowing the merchant to link the first and second purchases of goods or services without having had to ask the consumer for any personal information.
