Abstract: The present invention relates to a method and system for providing payments over a wireless connection. Instant messaging services—such as mobile text messaging—addressed to a command interpretation and processing system are utilized in conjunction with a checkout procedure on a mobile device to enable a user making a payment to simply define and confirm the amount of his or her payment, and the recipient. The checkout procedure can be completed with SMS, Mobile Web, Mobile App or IVR implementation. Previously Registered as well as new unregistered users are supported. The payer, through his or her mobile device, interacts with a system for managing mobile payment transactions that validates the sender and recipient of the funds, the presence of funds in a transacting account and other fraud management and authentication checks, and effects a settlement.
