Abstract: Ranking payment requests includes a peer-to-peer payment system that employs a server configured for receiving a payment request from a requester computing device; receiving location data of the requester network device; receiving a request for a ranking of payment requests; searching social network information of the payor for occurrences of the requester of the payment request; receiving location data of the payor network device, the location data comprising a location of the payor computing device and a location history of the payor computing device; searching a transaction history of the payor; ranking the payment requests based at least in part on one or more of the location of the requester, a strength of social network connections to the payor for each of the payment requesters, and number of previous transactions between the payor and the requester; and providing the ranking of the payment requests to the payor.

Abstract: A transfer management system receives a request to transfer an amount of funds from a transferring account maintained by a transferring bank to a receiving account maintained by a receiving bank. The transfer management system determines whether the transferring bank maintains an intermediate transferring account, and whether the receiving bank maintains an intermediate receiving account. If the transferring bank maintains an intermediate transferring account and the receiving maintains an intermediate receiving account, the transfer management system transmits to a transferring bank system of the transferring bank an intra-bank transfer request. The intra-bank transfer request is to transfer the amount of funds from the transferring account to the intermediate transferring account.

Abstract: The invention provides a computer-implemented method for using the social networking content of a user to determine authentication levels required for a peer-to-peer transaction. A user inputs transaction counter-party and transaction details into a payment application. The information can be transmitted to a server located in a peer-to-peer payment system. The system may search the social network content of the user to determine the account information of the counter-party and to assess the security risk of the counter-party according to a preconfigured set of factors that define the strength of the connection to the user. These factors may include the counter-party's status in the user's social networks, frequency of contact, prior transactions, or other factors that further establish a relationship. The system may determine the level of transaction authentication required to process the transaction. The user may enter the authentication data to complete the transaction.

Abstract: A user installs a Peer-to-Peer Payment Application (“PPA”) on their mobile device. The PPA transmits the location of the user device to a server located in a Peer-to-Peer Payment System (“PPS”). The PPS may search for other devices within a certain proximity to the user that may be active. The PPS may search the social network content of the user to determine if any of the proximate devices users are likely counter-parties. If more than one likely counter-party is identified, the PPS may rank the counter-parties according to a preconfigured set of factors that define the strength of the connection to the user. These factors may include their status in the user's social networks, frequency of contact, prior transactions, or other factors that further establish a relationship. The PPS may transmit the ranked list of likely counter-parties to the PPA for display to the user on the device.

Abstract: A group including plurality of users is established. A transaction record is maintained for the group that includes a plurality of payment transactions. Each of the plurality of payment transactions involves at least one user of the group. Additionally, a balance is maintained that indicates an amount owed by a first user of the group to a second user of the group based on one or more of the plurality of payment transactions. When a settling event occurs, the balance is settled by initiating a transfer of funds between the first user and the second user.

Abstract: A device to be used in conjunction with oxygen cylinders or other gas cylinders which will sound a warning and/or flash a light when the gas supply is running low and the cylinder is in need of replacement. A pin is inserted through a lens which normally is placed over a gas gauge dial wherein the gauge dial has a standard indicator arm which moves when the pressure decreases. When the indicator arm moves, normally in a counterclockwise direction, it will make contact with the pin when the level in the tank has been reduced to a point where it should be replaced. This will then complete an electrical circuit which would cause an alarm to sound and/or a light to flash. The circuit comprises essentially two lead wires each connected to a battery with one of the leads connected to a metal part of the regulator and another lead connected to the pin associated with the gauge.
