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.
