Abstract: This disclosure describes, in part, techniques for utilizing proxy contact information in order to allow merchants to communicate with customers. For instance, a payment service may receive, from a first merchant device, payment information and first contact information for a customer during a first transaction. The payment service may then associate the payment information with the first contact information. Next, the payment service may receive the payment information from a second merchant device during a second transaction. Based on receiving the payment information, the payment service may identify the first contact information using the association between the payment information and the first contact information, generate second contact information for the customer, associated the second contact information with the first contact information, and send the second contact information to the second merchant device.

Abstract: This disclosure describes techniques to infer customer communication preferences based on interactions between customers and merchants. In the past, merchants have typically asked customers to either opt-in or opt-out from receiving subsequent communications from the merchants. However, many customers simply choose the default setting, such that the resultant “selection” does not adequately reflect their desires regarding whether and how much future communication they would like to receive. This often results in high unsubscribe rates and/or ineffective merchant communication. The described techniques utilize behavior of a customer as a more accurate gauge of how receptive the customer is to receiving communications from a merchant.

Abstract: A payment processing system for mobile point-of-sale transactions from a mobile point of sale terminal including a payment card reader having a card interface configured to read data from a payment card, the payment processing system includes an automated support system for proactively generating and presenting support messages for merchants using a mobile point-of-sale terminal. The automated support system generates the support message using a current account context for the merchant account and a plurality of rules that indicate a problem with the merchant account. The automated support system is further configured to generate a plurality of rules for detecting merchant account problems using a knowledge database of support tickets that include a human generated response to a merchant account problem and a corresponding merchant account context at the time of the human generated response.
