Abstract: The present invention provides methods and systems for managing mobile virtual network operations. According to some embodiments, purchasing information, e.g., item, price, quantity, location, etc., may be collected using a mobile phone. The collected information may be used as part of a bonus or loyalty program. Collected information might be stored directly on a person's mobile phone. Alternatively, collected information might be stored by using the mobile phone to transfer the collected information to a server or servers. The system for tracking purchasing information may comprise a mobile communication device configured to connect to a transaction center via a mobile telephone network and to collect purchasing information for use by a loyalty program, a payment terminal device connected to a transaction center via a communication link, and a point of sale device, coupled to the payment terminal device and configured to provide items for purchase.
