Abstract: A computer-implemented method for facilitating a payment between merchants and consumers at a convention or other private, temporary event is implemented with a computer server programmed with pay application software. Profile information for at least one merchant and consumer, including identifying information and payment information, is received and stored in merchant and consumer portals. A purchase request identifying a product the consumer wishes to purchase is generated by an electronic device operated by the consumer while the consumer is attending the event. The purchase request is communicated to the server, which then retrieves transaction information related to the purchase request from the merchant and consumer portals. The pay application server then transmits the transaction information to a payment interchange, which transfers funds from the consumer to the merchant and sends payment confirmation back to the pay application server.

Abstract: Systems and methods are provided for controlling categories of users based on network activity associated with the users at web browsers. One exemplary method includes transmitting, by a user feedback server (UFS), a web site to a user at a communication device and soliciting a feedback input associated with a prior network activity of the user. The UFS receives the feedback input from the user for a network object. The feedback input includes a unique identifier (ID) and a network object identifier associated with the network object. The unique ID is associated with at least one of the user and the communication device. The UFS transmits the feedback input (or portion thereof) to a host, whereby the host is permitted, based on the unique ID and the network object identifier, to adjust inclusion of the user and/or the communication device in one or more categories of users and/or communication devices.
